5. Amphetamine-Based Stimulants
Amphetamine-based medications are prescribed for conditions such as attention-deficit/hyperactivity disorder (ADHD) and certain sleep disorders. They increase the activity of neurotransmitters such as dopamine and norepinephrine, which can improve attention and alertness.
When taken at prescribed doses under medical supervision, these medications are not established causes of dementia or permanent brain damage. However, misuse, excessive doses, or prolonged abuse of amphetamines can cause serious neurological and psychiatric complications.
