That question is part of the diagnosis decision tree. Per the DSM the 
distinction is the presence of significant impairment/impact on 

For ADD: "D. There is clear evidence that the symptoms interfere with, 
or reduce the quality of, social, academic, or occupational functioning."

For ASD: "D. Symptoms cause clinically significant impairment in social, 
occupational, or other important areas of current functioning."

And so on.
