There is no real catch all test to determine if a patient has ADHD, so most experts look for regular occurrences of some or all of the symptoms associated with ADHD. Factors such as activities being performed, the environment in which they are being performed and the patient’s history with those activities are also factors in diagnosing ADHD. Some of the major symptoms of ADHD are frequent procrastination, trouble completing tasks and a generally short attention span for non-preferred tasks. Hyperactivity which may manifest physically, emotionally, or verbally. Executive Dysfunction, which is when someone gets easily overwhelmed making decisions, poor time management, trouble multitasking and general disorganization. Emotional difficulties such as frequent mood swings, inability to control anger and frustration, fidgeting, restlessness, and impulsivity. For minor symptoms of ADHD your doctor may counsel some changes in diet, such as avoiding too much sugar or caffeine, more exercise, and structured routines to help deal with the symptoms. If symptoms are more severe your doctor may proscribe stimulant medication such as Methylphenidate or Amphetamines. As well the non-stimulant medication Atomoxetine has been available as a treatment since 2003.
