"AIDS dementia complex (ADC), or HIV-associated dementia (HAD), occurs primarily in persons with more advanced HIV infection. Symptoms include encephalitis (inflammation of the brain), behavioral changes, and a gradual decline in cognitive function, including trouble with concentration, memory, and attention. Persons with ADC also show progressive slowing of motor function and loss of dexterity and coordination. When left untreated, ADC can be fatal. It is rare when anti-retroviral therapy is used.
Milder cognitive complaints are common and are termed HIV-associated neurocognitive disorder (HAND). Neuropsychologic testing can reveal subtle deficits even in the absence of symptoms."
