Learning Disabilities
September 1993
Imagine having important needs and ideas to communicate, but being
unable to express them. Perhaps feeling bombarded by sights and sounds,
unable to focus your attention. Or trying to read or add but not being
able to make sense of the letters or numbers.
You may not need to imagine. You may be the parent or teacher of a
child experiencing academic problems, or have someone in your family
diagnosed as learning disabled. Or possibly as a child you were told
you had a reading problem called dyslexia or some other learning
handicap.
Although different from person to person, these difficulties make up the
common daily experiences of many learning disabled children,
adolescents, and adults. A person with a learning disability may
experience a cycle of academic failure and lowered self-esteem. Having
these handicaps--or living with someone who has them--can bring
overwhelming frustration.
But the prospects are hopeful. It is important to remember that a
person with a learning disability can learn. The disability usually
only affects certain limited areas of a child's development. In fact,
rarely are learning disabilities severe enough to impair a person's
potential to live a happy, normal life.
The stories of Susan, Wallace, and Dennis are representative of people
with learning disabilities, but the characters are not real. Of course,
people with learning disabilities are not all alike, so these stories
may not fit any particular individual.
Understanding the Problem
Susan
At age 14, Susan still tends to be quiet. Ever since she was a child,
she was so withdrawn that people sometimes forgot she was there. She
seemed to drift into a world of her own. When she did talk, she often
called objects by the wrong names. She had few friends and mostly
played with dolls or her little sister. In school, Susan hated reading
and math because none of the letters, numbers or "+" and "-" signs made
any sense. She felt awful about herself. She'd been told--and was
convinced--that she was retarded.
Wallace
Wallace has lived 46 years, and still has trouble understanding what
people say. Even as a boy, many words sounded alike. His father
patiently said things over and over. But whenever his mother was drunk,
she flew into a rage and spanked him for not listening. Wallace's
speech also came out funny. He had such problems saying words that in
school his teacher sometimes couldn't understand him. When classmates
called him a "dummy," his fists just seemed to take over.
Dennis
Dennis is 23 years old and still seems to have too much energy. But he
had always been an overactive boy, sometimes jumping on the sofa for
hours until he collapsed with exhaustion. In grade school, he never sat
still. He interrupted lessons. But he was a friendly, well-meaning
kid, so adults didn't get too angry. His academic problems became
evident in third grade, when his teacher realized that Dennis could only
recognize a few words and wrote like a first grader. She recommended
that Dennis repeat third grade, to give him time to "catch up." After
another full year, his behavior was still out of control, and his
reading and writing had not improved.
What Is a Learning Disability?
Unlike other disabilities, such as paralysis or blindness, a learning
disability (LD) is a hidden handicap. A learning disability doesn't
disfigure or leave visible signs that would invite others to be
understanding or offer support. A woman once blurted to Wallace, "You
seem so intelligent--you don't look handicapped!"
LD is a disorder that affects people's ability to either interpret what
they see and hear or to link information from different parts of the
brain. These limitations can show up in many ways--as specific
difficulties with spoken and written language, coordination,
self-control, or attention. Such difficulties extend to schoolwork and
can impede learning to read or write, or to do math.
Learning disabilities can be lifelong conditions that, in some cases,
affect many parts of a person's life: school or work, daily routines,
family life, and sometimes even friendships and lay. In some people,
many overlapping learning disabilities may be apparent. Other people
may have a single, isolated learning problem that has little impact on
other areas of their lives.
What Are the Types of Learning Disabilities?
"Learning disability" is not a diagnosis in the same sense as
"chickenpox" or "mumps." Chickenpox and mumps imply a single, known
cause with a predictable set of symptoms. Rather, LD is a broad term
that covers a pool of possible causes, symptoms, treatments, and
outcomes. Partly because learning disabilities can show up in so many
forms, it is difficult to diagnose or to pinpoint the causes. And no
one knows of a pill or remedy that will cure them.
Not all learning problems are necessarily learning disabilities. Many
children are simply slower in developing certain skills. Because
children show natural differences in their rate of development,
sometimes what seems to be a learning disability may simply be a delay
in maturation. To be diagnosed as a learning disability, specific
criteria must be met.
The criteria and characteristics for diagnosing learning disabilities
appear in a reference book called the DSM (short for the Diagnostic and
Statistical Manual of Mental Disorders). The DSM diagnosis is commonly
used when applying for health insurance coverage of diagnostic and
treatment services.
Learning disabilities can be divided into three broad categories:
- Developmental speech and language disorders
- Academic skills disorders
- "Other," a catch-all that includes certain coordination disorders
and learning handicaps not covered by the other terms
Each of these categories includes a number of more specific disorders.
Developmental Speech and Language Disorders
Speech and language problems are often the earliest indicators of a
learning disability. People with developmental speech and language
disorders have difficulty producing speech sounds, using spoken language
to communicate, or understanding what other people say. Depending on
the problem, the specific diagnosis may be:
- Developmental articulation disorder
- Developmental expressive language disorder
- Developmental receptive language disorder
Developmental Articulation Disorder-- Children with this disorder may
have trouble controlling their rate of speech. Or they may lag behind
playmates in learning to make speech sounds. For example, Wallace at
age 6 still said "wabbit" instead of "rabbit" and "thwim" for "swim."
Developmental articulation disorders are common. They appear in at
least 10 percent of children younger than age 8. Fortunately,
articulation disorders can often be outgrown or successfully treated
with speech therapy.
Developmental Expressive Language Disorder-- Some children with
language impairments have problems expressing themselves in speech.
Their disorder is called, therefore, a developmental expressive language
disorder. Susan, who often calls objects by the wrong names, has an
expressive language disorder. Of course, an expressive language
disorder can take other forms. A 4-year-old who speaks only in two-word
phrases and a 6-year-old who can't answer simple questions also have an
expressive language disability.
Developmental Receptive Language Disorder-- Some people have trouble
understanding certain aspects of speech. It's as if their brains are
set to a different frequency and the reception is poor. There's the
toddler who doesn't respond to his name, a preschooler who hands you a
bell when you asked for a ball, or the worker who consistently can't
follow simple directions. Their hearing is fine, but they can't make
sense of certain sounds, words, or sentences they hear. They may even
seem inattentive. These people have a receptive language disorder.
Because using and understanding speech are strongly related, many people
with receptive language disorders also have an expressive language
disability.
Of course, in preschoolers, some misuse of sounds, words, or grammar is
a normal part of learning to speak. It's only when these problems
persist that there is any cause for concern.
Academic Skills Disorders
Students with academic skills disorders are often years behind their
classmates in developing reading, writing, or arithmetic skills. The
diagnoses in this category include:
- Developmental reading disorder
- Developmental writing disorder
- Developmental arithmetic disorder
Developmental Reading Disorder-- This type of disorder, also known as
dyslexia, is quite widespread. In fact, reading disabilities affect 2
to 8 percent of elementary school children.
When you think of what is involved in the "three R's"--reading, 'riting,
and 'rithmetic--it's astounding that most of us do learn them. Consider
that to read, you must simultaneously:
- Focus attention on the printed marks and control eye movements
across the page
- Recognize the sounds associated with letters
- Understand words and grammar
- Build ideas and images
- Compare new ideas to what you already know
- Store ideas in memory
Such mental juggling requires a rich, intact network of nerve cells that
connect the brain's centers of vision, language, and memory.
A person can have problems in any of the tasks involved in reading.
However, scientists found that a significant number of people with
dyslexia share an inability to distinguish or separate the sounds in
spoken words. Dennis, for example, can't identify the word "bat" by
sounding out the individual letters, b-a-t. Other children with
dyslexia may have trouble with rhyming games, such as rhyming "cat" with
"bat." Yet scientists have found these skills fundamental to learning to
read. Fortunately, remedial reading specialists have developed
techniques that can help many children with dyslexia acquire these
skills.
However, there is more to reading than recognizing words. If the brain
is unable to form images or relate new ideas to those stored in memory,
the reader can't understand or remember the new concepts. So other
types of reading disabilities can appear in the upper grades when the
focus of reading shifts from word identification to comprehension.
Developmental Writing Disorder-- Writing, too, involves several brain
areas and functions. The brain networks for vocabulary, grammar, hand
movement, and memory must all be in good working order. So a
developmental writing disorder may result from problems in any of these
areas. For example, Dennis, who was unable to distinguish the sequence
of sounds in a word, had problems with spelling. A child with a writing
disability, particularly an expressive language disorder, might be
unable to compose complete, grammatical sentences.
Developmental Arithmetic Disorder-- If you doubt that arithmetic is a
complex process, think of the steps you take to solve this simple
problem: 25 divided by 3 equals ?
Arithmetic involves recognizing numbers and symbols, memorizing facts
such as the multiplication table, aligning numbers, and understanding
abstract concepts like place value and fractions. Any of these may be
difficult for children with developmental arithmetic disorders.
Problems with numbers or basic concepts are likely to show up early.
Disabilities that appear in the later grades are more often tied to
problems in reasoning.
Many aspects of speaking, listening, reading, writing, and arithmetic
overlap and build on the same brain capabilities. So it's not
surprising that people can be diagnosed as having more than one area of
learning disability. For example, the ability to understand language
underlies learning speak. Therefore, any disorder that hinders the
ability to understand language will also interfere with the development
of speech, which in turn hinders learning to read and write. A single
gap in the brain's operation can disrupt many types of activity.
"Other" Learning Disabilities
The DSM also lists additional categories, such as "motor skills
disorders" and "specific developmental disorders not otherwise
specified." These diagnoses include delays in acquiring language,
academic, and motor skills that can affect the ability to learn, but do
not meet the criteria for a specific learning disability. Also included
are coordination disorders that can lead to poor penmanship, as well as
certain spelling and memory disorders.
Attention Disorders
Nearly 4 million school-age children have learning disabilities. Of
these, at least 20 percent have a type of disorder that leaves them
unable to focus their attention.
Some children and adults who have attention disorders appear to daydream
excessively. And once you get their attention, they're often easily
distracted. Susan, for example, tends to mentally drift off into a
world of her own. Children like Susan may have a number of learning
difficulties. If, like Susan, they are quiet and don't cause problems,
their problems may go unnoticed. They may be passed along from grade to
grade, without getting the special assistance they need.
In a large proportion of affected children--mostly boys--the attention
deficit is accompanied by hyperactivity. Dennis is an example of a
person with attention deficit hyperactivity disorder--ADHD. They act
impulsively, running into traffic or toppling desks. Like young Dennis,
who jumped on the sofa to exhaustion, hyperactive children can't sit
still. They blurt out answers and interrupt. In games, they can't wait
their turn. These children's problems are usually hard to miss.
Because of their constant motion and explosive energy, hyperactive
children often get into trouble with parents, teachers, and peers.
By adolescence, physical hyperactivity usually subsides into fidgeting
and restlessness. But the problems with attention and concentration
often continue into adulthood. At work, adults with ADHD often have
trouble organizing tasks or completing their work. They don't seem to
listen to or follow directions. Their work may be messy and appear
careless.
Attention disorders, with or without hyperactivity, are not considered
learning disabilities in themselves. However, because attention
problems can seriously interfere with school performance, they often
accompany academic skills disorders.
What Causes Learning Disabilities
Understandably, one of the first questions parents ask when they learn
their child has a learning disorder is "Why? What went wrong?"
Mental health professionals stress that since no one knows what causes
learning disabilities, it doesn't help parents to look backward to
search for possible reasons. There are too many possibilities to pin
down the cause of the disability with certainty. It is far more
important for the family to move forward in finding ways to get the
fight help.
Scientists, however, do need to study causes in an effort to identify
ways to prevent learning disabilities.
Once, scientists thought that all learning disabilities were caused by a
single neurological problem. But research has helped
us see that the causes are more diverse and complex. New evidence seems
to show that most learning disabilities do not stem from a single,
specific area of the brain, but from difficulties in bringing together
information from various brain regions.
Today, a leading theory is that learning disabilities stem from subtle
disturbances in brain structures and functions. Some scientists believe
that, in many cases, the disturbance begins before birth.
Errors in Fetal Brain Development
Throughout pregnancy, the fetal brain develops from a few all-purpose
cells into a complex organ made of billions of specialized,
interconnected nerve cells called neurons. During this amazing
evolution, things can go wrong that may alter how the neurons form or
interconnect.
In the early stages of pregnancy, the brain stem forms. It controls
basic life functions such as breathing and digestion. Later, a deep
ridge divides the cerebrum--the thinking part of the brain--into two
halves, a right and left hemisphere. Finally, the areas involved with
processing sight, sound, and other senses develop, as well as the areas
associated with attention, thinking, and emotion.
As new cells form, they move into place to create various brain
structures. Nerve cells rapidly grow to form networks with other parts
of the brain. These networks are what allow information to be shared
among various regions of the brain.
Throughout pregnancy, this brain development is vulnerable to
disruptions. If the disruption occurs early, the fetus may die, or the
infant may be born with widespread disabilities and possibly mental
retardation. If the disruption occurs later, when the cells are
becoming specialized and moving into place, it may leave errors in the
cell makeup, location, or connections. Some scientists believe that
these errors may later show up as learning disorders.
Other Factors That Affect Brain Development
Through experiments with animals, scientists are tracking clues to determine what disrupts brain
development. By studying the normal processes of brain development,
scientists can better understand what can go wrong. Some of these
studies are examining how genes, substance abuse, pregnancy problems,
and toxins may affect the developing brain.
Genetic Factors-- The fact that learning disabilities tend to run in
families indicates that there may be a genetic link. For example,
children who lack some of the skills needed for reading, such as hearing
the separate sounds of words, are likely to have a parent with a related
problem. However, a parent's learning disability may take a slightly
different form in the child. A parent who has a writing disorder may
have a child with an expressive language disorder. For this reason, it
seems unlikely that specific learning disorders are inherited directly.
Possibly, what is inherited is a subtle brain dysfunction that can in
turn lead to a learning disability.
There may be an alternative explanation for why LD might seem to run in
families. Some learning difficulties may actually stem from the family
environment. For example, parents who have expressive language
disorders might talk less to their children, or the language they use may
be distorted. In such cases, the child lacks a good model for acquiring
language and therefore, may seem to be learning disabled.
Tobacco, Alcohol, and Other Drug Use-- Many drugs taken by the mother
pass directly to the fetus. Research shows that a mother's use of
cigarettes, alcohol, or other drugs during pregnancy may have damaging
effects on the unborn child. Therefore, to prevent potential harm to
developing babies, the U.S. Public Health Service supports efforts to
make people aware of the possible dangers of smoking, drinking, and
using drugs.
Scientists have found that mothers who smoke during pregnancy may be
more likely to bear smaller babies. This is a concern because small
newborns, usually those weighing less than 5 pounds, tend to be at risk
for a variety of problems, including learning disorders.
Alcohol also may be dangerous to the fetus' developing brain. It
appears that alcohol may distort the developing neurons. Heavy alcohol
use during pregnancy has been linked to fetal alcohol syndrome, a
condition that can lead to low birth weigh, intellectual impairment,
hyperactivity, and certain physical defects. Any alcohol use during
pregnancy, however, may influence the child's development and lead to
problems with learning, attention, memory, or problem solving. Because
scientists have not yet identified "safe" levels, alcohol should be used
cautiously by women who are pregnant or who may soon become pregnant.
Drugs such as cocaine--especially in its smokable form known as
crack--seem to affect the normal development of brain receptors. These
brain cell parts help to transmit incoming signals from our skin, eyes,
and ears, and help regulate our physical response to the environment.
Because children with certain learning disabilities have difficulty
understanding speech sounds or letters, some researchers believe that
learning disabilities, as well as ADHD, may be related to faulty
receptors. Current research points to drug abuse as a possible cause of
receptor damage.
Problems During Pregnancy or Delivery-- Other possible causes of
learning disabilities involve complications during pregnancy. In some
cases, the mother's immune system reacts to the ferns and attacks it as
if it were an infection. This type of disruption seems to cause newly
formed brain cells to settle in the wrong part of the brain. Or during
delivery, the umbilical cord may become twisted and temporarily cut off
oxygen to the fetus. This, too, can impair brain functions and lead to
LD.
Toxins in the Child's Environment-- New brain cells and neural networks
continue to be produced for a year or so after the child is born. These
cells are vulnerable to certain disruptions, also.
Researchers are looking into environmental toxins that may lead to
learning disabilities, possibly by disrupting childhood brain
development or brain processes. Cadmium and lead, both prevalent in the
environment, are becoming a leading focus of neurological research.
Cadmium, used in making some steel products, can get into the soil, then
into the foods we eat. Lead was once common in paint and gasoline, and
is still present in some water pipes. A study of animals sponsored by
the National Institutes of Health showed a connection between exposure
to lead and learning difficulties. In the study, rats exposed to lead
experienced changes in their brainwaves, slowing their ability to learn.
The learning problems lasted for weeks, long after the rats were no
longer exposed to lead.
In addition, there is growing evidence that learning problems may
develop in children with cancer who had been treated with chemotherapy
or radiation at an early age. This seems particularly true of children
with brain tumors who received radiation to the skull.
Are Learning Disabilities Related to Differences in the Brain?
In comparing people with and without learning disabilities, scientists
have observed certain differences in the structure and functioning of
the brain. For example, new research indicates that there may be
variations in the brain structure called the planum temporale, a
language-related area found in both sides of the brain. In people with
dyslexia, the two structures were found to be equal in size. In people
who are not dyslexic, however, the left planum temporale was noticeably
larger. Some scientists believe reading problems may be related to such
differences.
With more research, scientists hope to learn precisely how differences
in the structures and processes of the brain contribute to learning
disabilities, and how these differences might be treated or prevented.
Getting Help
Susan
Susan was promoted to the sixth grade but still couldn't do basic math.
So, her mother brought her to a private clinic for testing. The
clinician observed that Susan had trouble associating symbols with their
meaning, and this was holding back her language, reading, and math
development. Susan called objects by the wrong words and she could not
associate sounds with letters or recognize math symbols. However, an IQ
of 128 meant that Susan was quite bright. In addition to developing an
Individualized Education Plan, the clinician recommended that Susan
receive counseling for her low self-esteem and depression.
Wallace
In the early 1960s, at the request of his ninth grade teacher, Wallace
was examined by a doctor to see why he didn't speak or listen well. The
doctor tested his vocal cords, vision, and hearing. They were all fine.
The teacher concluded that Wallace must have "brain damage," so not much
could be done. Wallace kept failing in school and was suspended several
times for fighting. He finally dropped out after tenth grade. He spent
the next 25 years working as a janitor. Because LD frequently went
undiagnosed at the time when Wallace was young, the needed help was not
available to him.
Dennis
In fifth grade, Dennis' teacher sent him to the school psychologist for
testing. Dennis was diagnosed as having developmental reading and
developmental writing disorders. He was also identified as having an
attention disorder with hyperactivity. He was placed in an all-day
special education program, where he could work on his particular
deficits and get individual attention. His family doctor prescribed the
medication Ritalin to reduce his hyperactivity and distractibility.
Along with working to improve his reading, the special education teacher
helped him improve his listening skills. Since his handwriting was
still poor, he learned to type homework and reports on a computer. At
age 19, Dennis graduated from high school and was accepted by a college
that gives special assistance to students with learning disabilities.
How Are Learning Disabilities First Identified?
The first step in solving any problem is realizing there is one.
Wallace, sadly, was a product of his time, when learning disabilities
were more of a mystery and often went unrecognized. Today,
professionals would know how to help Wallace. Dennis and Susan were
able to get help because someone saw the problem and referred them for
help.
When a baby is born, the parents eagerly wait for the baby's first step,
first word, a myriad of other "firsts." During routine checkups, the
pediatrician, too, watches for more subtle signs of development. The
parents and doctor are watching for the child to achieve developmental
milestones. The developmental milestones chart (omitted here; see page
18 of brochure) lists a few of these markers and the ages and grades
that they typically appear.
Parents are usually the first to notice obvious delays in their child
reaching early milestones. The pediatrician may observe more subtle
signs of minor neurological damage, such as a lack of coordination. But
the classroom teacher, in fact, may be the first to notice the child's
persistent difficulties in reading, writing, or arithmetic. As school
tasks become more complex, a child with a learning disability may have
problems mentally juggling more information.
The learning problems of children who are quiet and polite in school may
go unnoticed. Children with above average intelligence, who manage to
maintain passing grades despite their disability, are even less likely
to be identified. Children with hyperactivity, on the other hand, will
be identified quickly by their impulsive behavior and excessive
movement. Hyperactivity usually begins before age 4 but may not be
recognized until the child enters school.
What should parents, doctors, and teachers do if critical developmental
milestones haven't appeared by the usual age? Sometimes it's best to
allow a little more time, simply for the brain to mature a bit. But if
a milestone is already long delayed, if there's a history of learning
disabilities in the family, or if there are several delayed kills, the
child should be professionally evaluated as soon as possible. An
educator or a doctor who treats children can suggest where to go for
help.
How Are Learning Disabilities Formally Diagnosed?
By law, learning disability is defined as a significant gap between a
person's intelligence and the skills the person has achieved at each
age. This means that a severely retarded 10-year-old who speaks like a
6-year-old probably doesn't have a language or speech disability. He
has mastered language up to the limits of his intelligence. On the
other hand, a fifth grader with an IQ of 100 who can't write a simple
sentence probably does have LD.
Learning disorders may be informally flagged by observing significant
delays in the child's skill development. A 2-year delay in the primary
grades is usually considered significant. For older students, such a
delay is not as debilitating, so learning disabilities aren't usually
suspected unless there is more than a 2-year delay. Actual diagnosis of
learning disabilities, however, is made using standardized tests that
compare the child's level of ability to what is considered normal
development for a person of that age and intelligence.
For example, as late as fifth grade, Susan couldn't add two numbers,
even though she rarely missed school and was good in other subjects.
Her mother took her to a clinician, who observed Susan's behavior and
administered standardized math and intelligence tests. The test results
showed that Susan's math skills were several years behind, given her
mental capacity for learning. Once other possible causes like lack of
motivation and vision problems were ruled out, Susan's math problem was
formally diagnosed as a specific learning disability.
Test outcomes depend not only on the child's actual abilities, but on
the reliability of the test and the child's ability to pay attention and
understand the questions. Children like Dennis, with poor attention or
hyperactivity, may score several points below their true level of
ability. Testing a child in an isolated room can sometimes help the
child concentrate and score higher.
Each type of LD is diagnosed in slightly different ways. To diagnose
speech and language disorders, a speech therapist tests the child's
pronunciation, vocabulary, and grammar and compares them to the
developmental abilities seen in most children that age. A psychologist
tests the child's intelligence. A physician checks for any ear
infections, and an audiologist may be consulted to rule out auditory
problems. If the problem involves articulation, a doctor examines the
child's vocal cords and throat.
In the case of academic skills disorders, academic development in
reading, writing, and math is evaluated using standardized tests. In
addition, vision and hearing are tested to be sure the student can see
words clearly and can hear adequately. The specialist also checks if
the child has missed much school. It's important to rule out these
other possible factors. After all, treatment for a learning disability
is very different from the remedy for poor vision or missing school.
ADHD is diagnosed by checking for the long-term presence of specific
behaviors, such as considerable fidgeting, losing things, interrupting,
and talking excessively. Other signs include an inability to remain
seated, stay on task, or take turns. A diagnosis of ADHD is made only
if the child shows such behaviors substantially more than other children
of the same age.
If the school fails to notice a learning delay, parents can request an
outside evaluation. In Susan's case, her mother chose to bring Susan to
a clinic for testing. She then brought documentation of the disability
back to the school. After confirming the diagnosis, the public school
was obligated to provide the kind of instructional program that Susan
needed.
Parents should stay abreast of each step of the school's evaluation.
Parents also need to know that they may appeal the school's decision if
they disagree with the findings of the diagnostic team. And like
Susan's mother, who brought Susan to a clinic, parents always have the
option of getting a second opinion.
Some parents feel alone and confused when talking to learning
specialists. Such parents may find it helpful to ask someone they like
and trust to go with them to school meetings. The person may be the
child's clinician or caseworker, or even a neighbor. It can help to
have someone along who knows the child and can help understand the
child's test scores or learning problems.
What Are the Education Options?
Although obtaining a diagnosis is important, even more important is
creating a plan for getting the right help. Because LD can affect the
child and family in so many ways, help may be needed on a variety of
fronts: educational, medical, emotional, and practical.
In most ways, children with learning disabilities are no different from
children without these disabilities. At school, they eat together and
share sports, games, and after-school activities. But since children
with learning disabilities do have specific learning needs, most public
schools provide special programs.
Schools typically provide special education programs either in a
separate all-day classroom or as a special education class that the
student attends for several hours each week. Some parents hire trained
tutors to work with their child after school. If the problems are
severe, some parents choose to place their child in a special school for
the learning disabled.
If parents choose to get help outside the public schools, they should
select a learning specialist carefully. The specialist should be able
to explain things in terms that the parents can understand. Whenever
possible, the specialist should have professional certification and
experience with the learner's specific age group and type of disability.
Some of the support groups listed at the end of this booklet can provide
references to qualified special education programs.
Planning a special education program begins with systematically
identifying what the student can and cannot do. The specialist looks
for patterns in the child's gaps. For example, if the child fails to
hear the separate sounds in words, are there other sound discrimination
problems? If there's a problem with handwriting, are there other
motor delays? Are there any consistent problems with memory?
Special education teachers also identify the types of tasks the child
can do and the senses that function well. By using the senses that are
intact and bypassing the disabilities, many children can develop needed
skills. These strengths offer alternative ways the child can learn.
After assessing the child's strengths and weaknesses, the special
education teacher designs an Individualized Educational Program (IEP).
The IEP outlines the specific skills the child needs to develop as well
as appropriate learning activities that build on the child's strengths.
Many effective learning activities engage several skills and senses.
For example, in learning to spell and recognize words, a student may be
asked to see, say, write, and spell each new word. The student may also
write the words in sand, which engages the sense of touch. Many experts
believe that the more senses children use in learning a skill, the more
likely they are to retain it.
An individualized, skill-based approach--like the approach used by
speech and language therapists--often succeeds in helping where regular
classroom instruction fails. Therapy for speech and language disorders
focuses on providing a stimulating but structured environment for
heating and practicing language patterns. For example, the therapist
may help a child who has an articulation disorder to produce specific
speech sounds. During an engaging activity, the therapist may talk
about the toys, then encourage the child to use the same sounds or
words. In addition, the child may watch the therapist make the sound,
feel the vibration in the therapist's throat, then practice making the
sounds before a mirror.
Researchers are also investigating nonstandard teaching methods. Some
create artificial learning conditions that may help the brain receive
information in nonstandard ways. For example, in some language
disorders, the brain seems abnormally slow to process verbal
information. Scientists are testing whether computers that talk can
help teach children to process spoken sounds more quickly. The computer
starts slowly, pronouncing one sound at a time. As the child gets
better at recognizing the sounds and heating them as words, the sounds
are gradually speeded up to a normal rate of speech.
Is Medication Available?
For nearly six decades, many children with attention disorders have
benefited from being treated with medication. Three rugs, Ritalin
(methylphenidate), Dexedrine (dextroamphetamine), and Cylert (pemoline),
have been used successfully. Although these drugs are stimulants in the
same category as "speed" and "diet pills," they seldom make children
"high" or more jittery. Rather, they temporarily improve children's
attention and ability to focus. They also help children control their
impulsiveness and other hyperactive behaviors.
The effects of medication are most dramatic in children with ADHD.
Shortly after taking the medication, they become more able to focus
their attention. They become more ready to learn. Studies by researchers have shown that at least 90 percent of
hyperactive children can be helped by either Ritalin or Dexedrine. If
one medication does not help a hyperactive child to calm down and pay
attention in school, the other medication might.
The drugs are effective for 3 to 4 hours and move out of the body within
12 hours. The child's doctor or a psychiatrist works closely with the
family and child to carefully adjust the dosage and medication schedule
for the best effect. Typically, the child takes the medication so that
the drug is active during peak school hours, such as when reading and
math are taught.
In the past few years, researchers have tested these drugs on adults who
have attention disorders. Just as in children, the results show that
low doses of these medications can help reduce distractibility and
impulsivity in adults. Use of these medications has made it possible
for many severely disordered adults to organize their lives, hold jobs,
and care for themselves.
In trying to do everything possible to help their children, many parents
have been quick to try new treatments. Most of these treatments sound
scientific and reasonable, but a few are pure quackery. Many are
developed by reputable doctors or specialists--but when tested
scientifically, cannot be proven to help. Following are types of
therapy that have not proven effective in treating the majority of
children with learning disabilities or attention disorders:
- Megavitamins
- Colored lenses
- Special diets
- Sugar-free diets
- Body stimulation or manipulation
Although scientists hope that brain research will lead to new medical
interventions and drugs, at present there are no medicines for speech,
language, or academic disabilities.
How Do Families Learn To Cope?
The effects of learning disabilities can ripple outward from the
disabled child or adult to family, friends, and peers at school or work.
Children with LD often absorb what others thoughtlessly say about them.
They may define themselves in light of their disabilities, as "behind,"
"slow," or "different."
Sometimes they don't know how they're different, but they know how awful
they feel. Their tension or shame can lead them to act out in various
ways--from withdrawal to belligerence. Like Wallace, they may get into
fights. They may stop trying to learn and achieve and eventually drop
out of school. Or, like Susan, they may become isolated and depressed.
Children with learning disabilities and attention disorders may have
trouble making friends with peers. For children with ADHD, this may be
due to their impulsive, hostile, or withdrawn behavior. Some children
with delays may be more comfortable with younger children who play at
their level. Social problems may also be a product of their disability.
Some people with LD seem unable to interpret tone of voice or facial
expressions. Misunderstanding the situation, they act inappropriately,
turning people away.
Without professional help, the situation can spiral out of control. The
more that children or teenagers fail, the more they may act out their
frustration and damage their self-esteem. The more they act out, the
more trouble and punishment it brings, further lowering their
self-esteem. Wallace, who lashed out when teased about his poor
pronunciation and was repeatedly suspended from school, shows how
harmful this cycle can be.
Having a child with a learning disability may also be an emotional
burden for the family. Parents often sweep through a range of emotions:
denial, guilt, blame, frustration, anger, and despair. Brothers and
sisters may be annoyed or embarrassed by their sibling, or jealous of
all the attention the child with LD gets.
Counseling can be very helpful to people with LD and their families.
Counseling can help affected children, teenagers, and adults develop
greater self-control and a more positive attitude toward their own
abilities. Talking with a counselor or psychologist also allows family
members to air their feelings as well as get support and reassurance.
Many parents find that joining a support group also makes a difference.
Support groups can be a source of information, practical suggestions,
and mutual understanding. Self-help books written by educators and
mental health professionals can also be helpful. A number of references
and support groups are listed at the end of this booklet.
Behavior modification also seems to help many children with
hyperactivity and LD. In behavior modification, children receive
immediate, tangible rewards when they act appropriately. Receiving an
immediate reward can help children learn to control their own actions,
both at home and in class. A school or private counselor can explain
behavior modification and help parents and teachers set up appropriate
rewards for the child.
Parents and teachers can help by structuring tasks and environments for
the child in ways that allow the child to succeed. They can find ways
to help children build on their strengths and work around their
disabilities. This may mean deliberately making eye contact before
speaking to a child with an attention disorder. For a teenager with a
language problem, it may mean providing pictures and diagrams for
performing a task. For students like Dennis with handwriting or
spelling problems, a solution may be to provide a word processor and
software that checks spelling. A counselor or school psychologist can
help identify practical solutions that make it easier for the child and
family to cope day by day.
Every child needs to grow up feeling competent and loved. When children
have learning disabilities, parents may need to work harder at
developing their children's self-esteem and relationship-building
skills. But self-esteem and good relationships are as worth developing
as any academic skill.
Sustaining Hope
Susan
Susan is now in ninth grade and enjoys learning. She no longer believes
she's retarded, and her use of words has improved. Susan has become a
talented craftsperson and loves making clothes and furniture for her
sister's dolls. Although she's still in a special education program,
she is making slow but steady progress in reading and math.
Wallace
Over the years, Wallace found he liked tinkering with cars and singing
in the church choir. At church, he met a woman who knew about learning
disabilities. She told him he could get help through his county social
services office. Since then, Wallace has been working with a speech
therapist, learning to articulate and notice differences in speech
sounds. When he complains that he's too old to learn, his therapist
reminds him, "It's never too late to work your good brain!" His state
vocational rehabilitation office recently referred him to a job-training
program. Today, at age 46, Wallace is starting night school to become
an auto mechanic. He likes it because it's a hands-on program where he
can learn by doing.
Dennis
Dennis is now age 23. As he walks into the college job placement
office, he smiles and shakes hands confidently. After shuffling through
a messy stack of papers, he finally hands his counselor a neatly typed
resume. Although Dennis jiggles his foot and interrupts occasionally,
he's clearly enthusiastic. He explains that because tape-recorded books
and lectures got him through college, he'd like to sell electronics.
Dennis says he'll also be getting married next year. He and his fiancee
are concerned that their children also will have LD. "But we'll just
have to watch and get help early--a lot earlier than I did!"
Can Learning Disabilities Be Outgrown or Cured?
Even though most people don't outgrow their brain dysfunction, people do
learn to adapt and live fulfilling lives. Dennis, Susan, and Wallace
made a life for themselves--not by being cured, but by developing their
personal strengths. Like Dennis' tape-recorded books and lectures, or
Wallace's hands-on auto mechanics class, they found alternative ways to
learn. And like Susan's crafts or Wallace's singing, they found ways to
enjoy their other talents.
Even though a learning disability doesn't disappear, given the right
types of educational experiences, people have a remarkable ability to
learn. The brain's flexibility to learn new skills is probably greatest
in young children and may diminish somewhat after puberty. This is why
early intervention is so important. Nevertheless, we retain the ability
to learn throughout our lives.
Even though learning disabilities can't be cured, there is still cause
for hope. Because certain learning problems reflect delayed
development, many children do eventually catch up. Of the speech and
language disorders, children who have an articulation or an expressive
language disorder are the least likely to have long-term problems.
Despite initial delays, most children do learn to speak.
For people with dyslexia, the outlook is mixed. But an appropriate
remedial reading program can help learners make great strides.
With age, and appropriate help from parents and clinicians, children
with ADHD become better able to suppress their hyperactivity and to
channel it into more socially acceptable behaviors. As with Dennis, the
problem may take less disruptive forms, such as fidgeting.
Can an adult be helped? For example, can an adult with dyslexia still
learn to read? In many cases, the answer is yes. It may not come as
easily as for a child. It may take more time and more repetition, and
it may even take more diverse teaching methods. But we know more about
reading and about adult learning than ever before. We know that adults
have a wealth of life experience to build on as they learn. And because
adults choose to learn, they do so with a determination that most
children don't have. A variety of literacy and adult education programs
sponsored by libraries, public schools, and community colleges are
available to help adults develop skills in reading, writing, and math.
Some of these programs, as well as private and nonprofit tutoring and
learning centers, provide appropriate programs for adults with LD.
What Aid Does the Government Offer?
As of 1981, people with learning disabilities came under the protection
of laws originally designed to protect the rights of people with
mobility handicaps. More recent Federal laws specifically guarantee
equal opportunity and raise the level of services to people with
disabilities. Once a learning disability is identified, children are
guaranteed a free public education specifically designed around their
individual needs. Adolescents with disabilities can receive practical
assistance and extra training to help make the transition to jobs and
independent living. Adults have access to job training and technology
that open new doors of opportunity.
Increased Services, Equal Opportunity
The Individuals with Disabilities Education Act of 1990 assures a public
education to school-aged children with diagnosed learning disabilities.
Under this act, public schools are required to design and implement an
Individualized Educational Program tailored to each child's specific
needs. The 1991 Individuals with Disabilities Education Act extended
services to developmentally delayed children down to age 5. This law
makes it possible for young children to receive help even before they
begin school.
Another law, the Americans with Disabilities Act of 1990, guarantees
equal employment opportunity for people with learning disabilities and
protects disabled workers against job discrimination. Employers may not
consider the learning disability when selecting among job applicants.
Employers must also make "reasonable accommodations" to help workers who
have handicaps do their job. Such accommodations may include shifting
job responsibilities, modifying equipment, or adjusting work schedules.
By law, publicly funded colleges and universities must also remove
barriers that keep out disabled students. As a result, many colleges
now recruit and work with students with learning disabilities to make it
possible for them to attend. Depending on the student's areas of
difficulty, this help may include providing recorded books and lectures,
providing an isolated area to take tests, or allowing a student to tape
record rather than write reports. Students with learning disabilities
can arrange to take college entrance exams orally or in isolated rooms
free from distraction. Many colleges are creating special programs to
specifically accommodate these students.
Programs like these made it possible for Dennis to attend and succeed in
college. The HEATH Resource Center, sponsored by the American Council
on Education, assists students with learning disabilities to identify
appropriate colleges and universities. Information on the HEATH center
and related organizations appears at the end of this brochure.
Public Agency Support
Effective service agencies are also in place to assist people of all
ages. Each state department of education can help parents identify the
requirements and the process for getting special education services for
their child. Other agencies serve disabled infants and preschool
children. Still others offer mental health and counseling services.
The National Information Center for Children and Youth can provide
referrals to appropriate local resources and state agencies.
Counselors at each state department of vocational rehabilitation serve
the employment needs of adolescents and adults with learning
disabilities. They can refer adults to free or subsidized health care,
counseling, and high school equivalence (GED) programs. They can assist
in arranging for job training that sidesteps the disability. For
example, a vocational counselor helped Wallace identify his aptitude for
car repair. To work around Wallace's language problems, the counselor
helped locate a job-training program that teaches through demonstrations
and active practice rather than lectures.
State departments of vocational rehabilitation can also assist in
finding special equipment that can make it possible for disabled
individuals to receive training, retain a job, or live on their own.
For example, because Dennis couldn't read the electronics manuals in his
new job, a vocational rehabilitation counselor helped him locate and
purchase a special computer that reads books aloud.
Finally, state-run protection and advocacy agencies and client
assistance programs serve to protect these fights. As experts on the
laws, they offer legal assistance, as well as information about local
health, housing, and social services.
What Hope Does Research Offer?
Sophisticated brain imaging technology is now making it possible to
directly observe the brain at work and to detect subtle malfunctions
that could never be seen before. Other techniques allow scientists to
study the points of contact among brain cells and the ways signals are
transmitted from cell to cell.
Studies of identical and fraternal twins are also being conducted.
Identical twins have the same genetic makeup, while fraternal twins do
not. By studying if learning disabilities are more likely to be shared
by identical twins than fraternal twins, researchers hope to determine
whether these disorders are influenced more by genetic or by
environmental factors. One such study is being conducted by scientists
funded by the National Institute of Child Health and Human Development.
So far, the research indicates that genes may, in fact, influence the
ability to sound out words.
Animal studies also are adding to our knowledge of learning disabilities
in humans. Animal subjects make it possible to study some of the
possible causes of LD in ways that can't be studied in humans. One NIMH
grantee is researching the effects of barbiturates and other drugs that
are sometimes prescribed during pregnancy. Another researcher
discovered through animal studies that certain prenatal viruses can
affect future learning. Research of this kind may someday pinpoint
prenatal problems that can trigger specific disabilities and tell us how
they can be prevented.
Animal research also allows the safety and effectiveness of experimental
new drugs to be tested long before they can be tried on humans. One
NIH-sponsored team is studying dogs to learn how new stimulant drugs
that are similar to Ritalin act on the brain. Another is using mice to
test a chemical that may counter memory loss.
This accumulation of data sets the stage for applied research. In the
coming years, research will focus on identifying the
conditions that are required for learning and the best combination of
instructional approaches for each child.
Piece by piece, using a myriad of research techniques and technologies,
scientists are beginning to solve the puzzle. As research deepens our
understanding, we approach a future where we can prevent certain brain
and mental disorders, make valid diagnoses, and treat each effectively.
