Multimodality evoked potentials in HIV infected subjects: A longitudinal study

Abstract

18 subjects with symptomless HIV infection were investigated with multimodal evoked potentials for possible CNS involvement and again after an 8-12 month interval. 13 subjects showed neuropsychological changes, which were confirmed at the second examination. The 5 subjects found normal remained so at the second examination. On WAIS assessment the only patient to earn pathological scores was the one with the greatest evoked potentials changes. Thus the evoked potentials procedure proved capable of identifying early CNS involvement by HIV infection.

Event related brain potential differences in attentional processing in HIV positive subjects.

“…Similarly, Koralnik et al (1990) and Cazzullo et al (1990) reported slowed somatosensory ERPs in relatively healthy (asymptomatic) HIV patients.…”
