Symptoms and Signs of Adult ADHD (Attention Deficit Hyperactivity Disorder in Adults)

Doctor's Notes on Adult ADHD (Attention Deficit Hyperactivity Disorder in Adults)

Adult ADHD (Attention Deficit Hyperactivity Disorder in Adults) is defined as a neurodevelopmental disorder that includes primary problems with inattention and/or activity in adults (there is still some controversy about the definition to include substance use, sleep disorders and others). Signs and symptoms include hyperactivity (inner restlessness, can’t relax, unhappy when inactive), impulsivity (impatient, snap decisions, rapidly changing tasks) and inattention (disorganized, poor time management, misses parts of conversations).

Adult ADHD is thought to be caused by both genetics and life-experience factors that theoretically may trigger brain chemicals like dopamine and norepinephrine to have abnormal levels at different brain locations.
