How is ADHD diagnosed?

There is no single medical, physical, or other test for ADHD. To determine if you have the disorder, a doctor or other health professional uses these tools:

1.A checklist of symptoms
2.Tests that tell him or her about the person's behavior
3.Answers to questions about the person's past and present problems
4.Information from family members or someone close to you
5.A medical exam to rule out other medical causes for symptoms

ADHD tests do not diagnosis. There is no single test that can diagnosis ADHD.
