Serial electroencephalograms (EEGs) and multimodality evoked potentials (EPs) were performed along with neurological and neuropsychological evaluation, cerebrospinal fluid assessment and magnetic resonance imaging at 6 month intervals in 73 neurologically asymptomatic HIV infected subjects. The results were compared with 50 age- and sex-matched controls. EEG was abnormal in 2 subjects (3%) initially and was abnormal in 7 (9%) subjects by the last examination. EEG abnormality (diffuse slowing) correlated significantly with slowed reaction time in neuropsychological testing (P < 0.05). VEP and BAEP provided low yields of 1.3% and 4% respectively. SEP was abnormal in 7 (9%) of the subjects initially and in 10 (13%) subjects by the last testing, with 80% of the abnormalities seen on the posterior tibial study. In 3 subjects, initial SEP abnormalities predicted later development of myelopathy and peripheral neuropathy. Event-related auditory evoked potentials were performed in 39 subjects. They were abnormal in 5 subjects initially (12%) and in 6 subjects (15%) by the last examination and more commonly in advanced stages of the illness with lower T4 counts. This data shows the evolution and association of electrophysiological abnormalities in early HIV infection and suggests a predictive value for SEP in HIV infected asymptomatic individuals.
