CSF amyloid β42 and tau levels correlate with AIDS dementia complex

There is concern that AIDS dementia complex (ADC) may be complicated by Alzheimer disease (AD). Because AD presence and risk are related to CSF beta-amyloid(1-42) (Abeta42), total tau (t-tau), and phosphorylated tau (p-tau), the authors examined these in ADC, AD, and controls. ADC had significantly decreased CSF Abeta42 and increased t-tau and p-tau concentrations similar to AD, suggesting that ADC may be associated with AD or an AD-like process.
