Response from Dr. Henry
HIV is a neurotrophic virus meaning that it hones in to the brain and other nerves. In the days before treatment a high percentage of AIDS patients developed dementia (loss of memory, confused thinking, often trouble walking and going to the bathroom ). HIV therapy dramatically decreased the rate that patients developed dementia. Patients still develop dementia despite therapy often in the setting of resistant virus (drugs not working as well) and a falling CD4 count. The HIV drugs themselves have not been linked to directly causing dementia though certain drugs (particularly efavirenz) can cause some confused thinking. KH
