There is no single test that will identify ADHD, and there are no specific genetic or biological indicators that will lead to a diagnosis. Instead, it is necessary to consult a doctor who will conduct a comprehensive evaluation which will include extensive examination of past behavior, and should also include a physical exam to rule out any other possible source of the symptoms.
ADHD symptoms differ from person to person, but according to the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, which is often used in ADHD research studies, they can include:
-Difficulty organizing tasks and activities
-Often losing things necessary for tasks or activities
-Often easily distracted by outside stimuli
-Not listening when spoken to directly
-Difficulty awaiting turn
-Difficulty playing or engaging in leisure activities quietly
All of the symptoms listed by the APA (and these are just a few) are meant to describe those found in children, but they can be used as a general guideline for adults as well. However, adult symptoms can manifest themselves in more subtle ways, and the hyperactivity seen in children is often less evident in adults. Instead, adults may be restless, on edge, and have trouble relaxing.
Diagnosing ADHD in adults is made more complex by the variety of conditions which can share similar symptoms. These conditions include drug or alcohol dependency, depression and thyroid dysfunction. trike
