IMO, it's what happens when you get decisions by committee. Short Term memory CAN be ADHD, but it also can be depression... there are so many things that are in a diagnosis and why ADHD is comorbid with so many other diags. I've also been finding in my own research that ADHD seems to be a good extension of the autism spectrum, and in and of itself is a spectrum.

If you haven't yet - get Driven to Distraction and the related books by the two authors. It's got diagnostic and coping advice and I found it very useful.

[sigh] I really should finish off my degree and all that, shouldn't I?
