Article on ADD and Non Verbal Learning Disorder

Not only have I been doing research on Asperger's syndrome but I have also come across a condition called Non Verbal Learning Disorder which seems to be related or similar.
I have, in the past, been diagnosed with ADD. I always had the feeling that the diagnoses was not exactly correct.

Maybe It’s Not ADD After All

Here are a few highlights from the magazine:

Marci did well academically in grades one and two, although she didn't have many friends. Her third-grade teachers said she seemed inattentive in class, blurted out inappropriate comments, and bumped into classmates clumsily when they lined up for recess. Later that year, Marci was diagnosed with ADD. But Ritalin didn't help. Neither did Adderall.

Given her obvious intelligence, her teachers considered her C average evidence of laziness or defiance.

Nonverbal learning disorder (NLD) is a constellation of brain-based difficulties. Once considered rare, NLD is now thought to be as prevalent as dyslexia. Strongly genetic in origin, NLD affects girls as freqently as boys and is characterized by poor visual, spatial, and organizational skills, poor motor performance, and difficulty recognizing and processing nonverbal cues - body language, facial expression, and the nuances of conversation.

* Despite their facility with language, kids with NLD often have poor reading comprehension. A child with NLD may miss the forest and the trees because of his intense focus on the leaves. After reading a book about the Civil War, for instance, the child might be able to name and describe each battlefield - yet fail to recognize that the conflict was about slavery and federalism.

At first glance, children with NLD seem to behave like those with ADD, but the appropriate interventions are not the same. A child with NLD may have trouble sitting still and may bump into people. But this isn't due to hyperactivity - it's due to his poor balance and coordination, and trouble with visuospatial relationships.

NLD varies from child to child, and is not defined as a separate entity in the Diagnostic and Statistical Manual. For diagnosis, a child must undergo neuropsychological testing, speech and language assessment, and educational and occupational therapy evaluations.

kids with NLD usually demonstrate a verbal I.Q. that's 20 or more points higher than their performance I.Q. (Verbal I.Q. is a measure of a child's language ability. Performance I.Q. measures how well he makes use of what he knows.) Another test, the Brown ADD Scales, can help differentiate NLD from ADD.
