In the disorder discovered by Hans Asperger in the 1940’s,
the classical autistic symptoms — low capacity for communication
and social interaction, restricted and repetitious stereotyped behavior — take
a different and less disabling form than the symptoms found in infantile
autism. Asperger’s disorder (or syndrome) was added to the American
Psychiatric Association’s official diagnostic manual in 1994
and is believed to affect about one in 300 children (and adults), nearly
90% of them male.
Despite normal and sometimes superior intelligence, people with Asperger’s
have difficulty understanding social conventions and reading social cues.
As a result, they often seem tactless or rude, and making friends can
be hard for them. They may be unable to take hints, keep secrets, or
understand metaphor, irony, and humor. The meaning of gestures, tone
of voice, and facial expressions are a mystery to them, and their own
body language and expressions may be inappropriate or hard to interpret.
They stand too close, talk too loudly, and don’t make eye contact.
Asperger’s syndrome is distinguished from the more severe forms
of autism, which often involve mental retardation, no language or extremely
limited language, and almost complete social isolation. Asperger’s
is sometimes distinguished from a special category of “high-functioning” autism,
chiefly on the grounds that it implies better verbal than nonverbal intelligence.
Definition of Asperger’s
In a child or adult with no deficiencies in overall intellectual
development, self-help skills, or language,
A. At least two of the following:
1. Difficulty using gaze, facial expressions, gestures, and
body posture normally in social interactions.
2. Failure to develop appropriate relationships with others
the same age.
3. Apparent lack of spontaneous desire to share interests,
achievements, or pleasures with others.
4. Failure to reciprocate, socially or emotionally.
B. At least one of the following:
1. Abnormally intense preoccupation with any single interest,
or preoccupation with an abnormally narrow interest.
2. Rigid insistence on certain seemingly pointless routines
3. Stereotyped and repetitive movements.
4. Preoccupation with parts of objects.

The autistic spectrum has strong genetic roots. About a third of the
parents of a child with Asperger’s syndrome will have at least
some related symptoms. Sometimes the condition is identified only in
adulthood, when a father recognizes his own symptoms in his child or
a wife recognizes them in her husband. Despite this hereditary basis,
there is no evidence so far for a specific organic cause.
One popular theory is that people with Asperger’s syndrome and
other autistic disorders lack a “theory of mind” — the
intuitive understanding that others have their own thoughts and feelings.
As a result, they cannot imagine their way into the minds of others to
anticipate their responses. Instead, they have to infer other people’s
feelings, intentions, and interests laboriously, using explicit rules.
Brain scans show that in most of us the amygdala, a center of emotion,
is activated when we judge facial expressions. In people with Asperger’s
syndrome, the area that lights up is the prefrontal cortex, a seat of
judgment and planning. They are thinking out the meaning of the expression
instead of responding to it immediately.
Ideally, an experienced pediatric neurologist, child psychologist or
psychiatrist, or developmental psychologist should diagnose Asperger’s
disorder. It cannot be identified by a single test, and an interview
in an office can be misleading because these children often handle themselves
well in a one-on-one situation with an adult. It’s important to
learn about the child’s history and how he or she behaves with
other children in school and at play.
The line between a normal boy’s fascination with the latest computer
game and a symptom of Asperger’s disorder can be difficult to draw.
But the more unusual and intense a restricted interest is, and the earlier
in life it appears, the more it suggests Asperger’s. It is also
a possible diagnosis if a child seems to look through rather than at
other people, if his voice seems to lack normal emotional inflections,
or if he is unusually sensitive to loud sounds or the feel of clothes.
Under federal law, children with developmental disorders, including
Asperger’s, are eligible for special education appropriate to their
needs. They can receive an individual education plan that may provide
teacher’s aides, tutoring, a special curriculum, or in a few cases,
People with Asperger’s can also be helped by individual or group
therapy, especially if they have other symptoms such as obsessive-compulsive
routines or depression. They may need help in managing anger and anxiety
arising from social rejection or bullying. Depression often becomes a
problem for them in adolescence, when they may feel socially excluded
and disdained by members of the opposite sex without quite understanding
why. In marriage, they are usually reliable, faithful, and loyal, but
may seem emotionally distant to their partners.
Asperger’s syndrome is one of those conditions that raises the
question of where to draw the line between normal and abnormal and what
to do about it. The symptoms of Asperger’s are common among scientists
and engineers, who spend much of their time engaged with physical nature
and machines that have no moods, thoughts, or intentions to confuse them.
It’s also been said that Asperger’s is an extreme variant
of the “male mind,” representing rule-based, systematic thinking.
From an early age, boys are more likely than girls to be interested in
ordered lists and mechanical models.
Whether that distinction is valid or not, from their own perspective
many people with Asperger’s and Asperger-like symptoms are not
disabled but different. They are capable of leading satisfying lives — and
providing challenges and opportunities that fit their talents as well
as their limitations is not necessarily the same as treating a disorder.
