you touch on an issue that I have noticed as well: The overlapping of symptoms between different disorders (syndromes, or whatever we choose to call it).

You mention among others Asperger’s Syndrome as one of the diagnoses that have been used wrongly before ADD/ADHD became more widely known, and no doubt this actually has happened (and happens still in some parts of the world).

That Asperger’s Syndrome also is one of the not well known disorders until recent years has led to the same kind of misdiagnosis in that people who have Asperger’s Syndrome sometimes are diagnosed as having ADD/ADHD.

Still, there are significant differences between Asperger’s Syndrome and ADHD or ADD.
What I am wondering about regarding this: When a person with Asperger’s Syndrome displays a lot of symptoms which without the Asperger’s Syndrome would be an ADHD or ADD diagnosis, does he then actually have two disorders (or syndromes), namely Asperger’s Syndrome AND ADD/ADHD, or are the ADHD symptoms part of the Asperger’s Syndrome?

It might seem a straight forward question easy to answer, but I have never met a person with Asperger’s Syndrome who doesn’t have ADD- and/or ADHD-like symtoms. And that, I think, makes it a fair to ask if ADD/ADHD is an inherent part of Asperger’s Syndrome.

I also often see the two things treated as related conditions, and I wonder if the neurological and neuro-psychological research has provided any results that might shed some light unto the question about the relationship between ADD/ADHD and Asperger’s Syndrome.
The issue is not less significant when we take into account that Asperger’s Syndrome actually is a condition on the Autism Spectrum.
