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
- 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.

It is not clearly understood how HIV infection causes ADC.
Factors that may increase your chance of having ADC include:
- Untreated HIV infection
- Late-stage AIDS
Symptoms usually develop slowly and worsen over time. They can be grouped into stages:
- Difficulty concentrating
- Difficulty remembering details, such as phone numbers, appointments, or tracking daily activities
- Slowed thinking
- Longer time needed to complete complicated tasks
- Unsteady walking, tremor, or difficulty keeping balance
- Poor hand function
- Change in handwriting
- More focus and attention needed
- Slow responses
- Frequently dropping objects
- Feelings of indifference or apathy
- Slowness or difficulty with normal activities, such as eating or writing
Walking, balance, and coordination require a great deal of effort at this stage.
- Loss of bladder or bowel control
- Abnormal gait, making walking more difficult
- Withdrawing from life
- Severe mental disorders, such as psychosis or mania
- Unable to leave bed
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
