processing
problems. (Compared to NLD children who often have the same problem.
For these children/teens, however, the problem is dysgraphia,
not processing. It is a motor problem, not a cognitive problem.)
Comparison
of AS, NLD, and High Functioning Autism
Asperger's syndrome is considered by many to be an Autism Spectrum
Disorder
(ASD) and
is often confused with NLD and high functioning autism. Here is an
overview comparison of these three:
James was an extremely negative and
extremely bright, 14 year old who had been
diagnosed with Asperger's Syndrome, depression, and
oppositional defiance disorder. He was a very lonely and angry young
man.
His world was made of things, pets, and people, in
that order of
preference. People, including his family, were way down on his list of
things he liked. His parents were both highly articulate and well
educated. James had a younger sister that did not have any of his
problems and seemed a normal child by all counts.
James preferred computer games and reading over
relationships. He had a large vocabulary and liked to write. He was
working on a fantasy book with great fervor. His
characters in the book, however, had the depth of computer
game characters.
James had the social skills of a rock and
non-verbal learning disorder (NLD). The only real person in James'
world was himself as far as he was concerned. All others were just
there to serve or annoy him. His conversations were one-dimensional,
consisting primarily about what ever topic he was obsessed with at the
time.
He was also not good at sports and would try to
avoid anything physical. He had only marginal hand-eye coordination and
in general was very awkward when he tried physical games and sports.
Unfortunately for him, his therapist liked sports and occasionally used
them in his therapy.
James had great difficulty recognizing other
people's personal
boundaries. One of his worst habits was walking up to someone
and poking them. It was his
way of trying to be friendly but would really offend others. He would
interrupt other's conversations or otherwise impose himself intrusively.
We spent a lot of time in therapy working on his social skills. This
included how to carry on a real conversation with someone. That meant
social courtesies and norms, such as saying "hello" or asking "how are
you
doing". He worked on learning to actually listen to what the
other
person was saying and responding appropriately to that.
We also spent a lot of time helping him learn to recognize body and
facial language in context of social interactions. His brilliant
intellect allowed him to do cognitively what most of us do naturally
and easily. Even with his intellect, this would be a lifelong challenge
for him. We also worked a lot on his learning to respect other
people's personal boundaries.
Finally, we got him involved in sports. I would go out and we would
play basketball or catch with a football. He was encouraged to
participate in athletic activities at his school. He did get better at
some of these and actually had fun at them, but it took some doing.
What causes AS? Is it genetic? Are mirror neurons involved?

Brain
differences
Research
is pointing to brain abnormalities as the underlying cause of AS.
Researchers have used brain imaging techniques that point to structural
and functional differences in specific regions of the brains of AS
children versus normal children. These differences most likely
originate during embryonic development and result in a "wiring"
difference in the brains of AS children. This difference is in the
control of thoughts and behaviors.
Looking at how AS children brains functioned in tasks that required
them to use their judgment, one study found a reduction in activity in
the frontal lobe of the brain. In another study, difference were found
in AS children when asked to respond to facial expressions (see mirror
neurons below). In a study with AS adults, a protein that correlates
with obsessive/repetitive behaviors was found in abnormal levels.
Genetics
Asperger's syndrome along with ASD's
tends to run in families. In these families there is a higher incidence
of family members that have Asperger's-like behavioral symptoms but not
as full blown. These symptoms included some difficulties in social
interactions, reading, and/or language skills.
However, a specific gene for Asperger's syndrome has not been
identified. Most
likely AS is a what is known as a polygenic trait, that is it
determined
by several genes with genetic variants (alleles) that make an
individual carrying them vulnerable to developing AS. There
may be both genetic and environmental components involved. This would
give rise to a range of AS severity and symptoms.
Mirror
neurons
Mirror neurons are an important class of recently discovered neurons
that enable us to recognize and interpret emotions and body language in
others and to learn by imitation. They are critical for normal social
interactions. Want to read more about mirror neurons, click here.
There is increasing evidence that ASD's
is a result of deficit in mirror neurons or dysfunction of the same.

According to the National Institute of Neural Disorders and Strokes,
the
ideal treatment for Asperger's syndrome needs to coordinate therapies
that address the
three
core symptoms of the disorder: communication skills,
obsessive/ repetitive routines, and physical clumsiness. Treatment
needs to be individualized for the teen's specific symptoms.
In Jame's case above, depression was co-morbid with his other AS
symptoms. Also, unlike many AS teens, James had good writing skills.
Consequently, we also treated the depression and encouraged his
writing. He was working on his first book by the end of
therapy and had dreams of being a writer.
Effective treatment programs build on the teen’s interests and includes
structure in terms of his/her schedule and living and school
environments. Predictability in their schedule is important
for these teens. Tasks need to be broken down into simple series of
steps. Parents often need coaching on how to do these.
Additionally, Reality Therapy (see choices and consequences) can be
very effective with these teens.
Therapy often includes:
social skills training, usually in the form of
group therapy that teaches teens the skills needed to interact
successfully with others
cognitive behavioral and/or Reality therapy
appropriate medication, for
co-existing conditions such as depression and anxiety
occupational or physical therapy, if sensory
integration
problems or poor motor coordination are problems
specialized speech/language therapy to help
them with the normal give and take of speech
parent training (coaching) and
support, so that parents can use behavioral techniques at home
Equine
Assisted Treatment
Our experience is that AS teens can often relate
better to pets and horses than people. Equine Assisted Counseling
sessions can serve as bridge to help AS teens gain self-confidence,
become more sensitive to body language, and to develop better problem
solving skills. They seem to be more relaxed with the horses once they
overcome their initial hesitancy with these large, powerful animals
that readily accept them for who they are.
