People taking high doses of amphetamines, often prescribed for treating attention-deficit/hyperactivity disorder (ADHD), may have higher risks of developing psychosis and mania, a new study has found.
Researchers at McLean Hospital, the largest psychiatric affiliate of Harvard Medical School, found that people taking high doses of the stimulant amphetamine, the active ingredient in ADHD drugs such as Adderall, face a 5.3-fold higher chance of experiencing a psychotic or manic episode.
