New research published in Neurology suggests that amyloid, one of the proteins associated with Alzheimer's disease, may also play a role in the memory loss of people with HIV. Researchers examined cerebrospinal fluid (CSF) and found that the amount of amyloid was lower in Alzheimer's patients and HIV patients with memory problems, when compared to HIV patients without memory problems and healthy people.
