AIDS dementia complex (ADC) can occur in people with
AIDS. ADC results in changes in multiple neurologic areas:
Cognition—the ability to understand, process, and remember information
Behavior—difficulty performing daily tasks
Emotions—may have personality changes and
depression Motor coordination—the ability to coordinate muscles and movement
ADC is a common nervous system complication of late-stage HIV infection.
HIV destroys white blood cells vital to the immune system.
