I recieved the diagnosis of Asperger's Syndrome when I was 14.
For those who are not aware of it, basically it's an autistic spectrum disorder. It's not a disease, you can't "catch" it and for the most part I am rather well functioning. People with the diagnosis have varying degrees of severity from needing job coaches to being fully functioning and independant. (Yours truly)
One of the symptoms (I prefer to think of them as "traits") of Asperger's is obsessive focus on a favorite topic or object. Some Aspies become experts on vacumm cleaners, for example, or can talk at length about their favorite TV shows, the Solar System, etc.
I wondered if there were any other members on this board who currently held the diagnosis.
Oh, and if you want to read an article I wrote about why I do not feel Asperger's is related to genetics, or inherited, check out this link: If Asperger's Is Genetic then So is my Credit Card Debt
