How do i know if i have autism or adhd?

You share your concerns with your doc and have an evaluation arranged if there are suggestive signs. I am very leery of any adult labeled with ADHD that did not have it in full form by the age 6, but it could happen. The autism tag has been broadened to include many alterations in function. A developmental or educational psychologist can put together an evaluation that could sort out the issues.

Please see a Clinical Psychologist for a complete evaluation to determine what your problem is. This is not something you can figure out on your own.
