This paper reveals how HIV affects the cerebral cortex, revealing deficits in motor areas that are linked with T-cell decline and
with cognitive impairment.

Biomarker for Alzheimer's Disease: An MRI Study of 676 AD, MCI, and Normal Subjects, NeuroImage, in press, July 2008.
[1.9MB, .pdf] [NEW]
This paper is about Alzheimer's disease and not HIV, but it shows how the 3D profile of brain degeneration
in 676 people correlates with genetic measures, cognitive decline, and future
outcomes. We are beginning to use this method to track HIV-related brain change.
