Abstract：
:Viral infections of the brain and spinal cord cause significant morbidity and mortality in patients afflicted with AIDS. Debate continues over the specific mechanisms and pathways of how HIV-1 manifests itself in the brain and spinal cord. Attempts to predict which seropositive patients develop neurocognitive deficits caused by HIV-1 and how soon these deficits will occur in the course of disease have had limited success. The neuropathologic changes of HIV-1 must be distinguished from other viral infections, such as cytomegalovirus, JC papovavirus (progressive multifocal leukoencephalopathy), herpes simplex virus type 1, and varicella-zoster virus. In addition to cerebral spinal fluid sampling and serum testing, some specific features are seen with contrast-enhanced CT, MR imaging, proton MR spectroscopy, SPECT, and PET.
