Electrophysiological methods in the diagnosis of subclinical cognitive impairment in HIV-infected patients

Abstract

With a goal of the early detection of subclinical cognitive impairment and damage of the central nervous system in the early stages HIV infection the complex neurophysiological study (electroencephalogram, cognitive evoked potentials of auditory and visual modalities, complex sensory-motor reactions, visual evoked potentials) in 20 patients with HIV infection was performed. Electrophysiological signs of subclinical cognitive impairment and non-specific subclinical involvement of central nervous system were found. Application of the complex electrophysiological study by evaluating the function of widespread neuronal networks has allowed to increasing the sensitivity of early diagnosis of subclinical cognitive impairment in HIV-infected patients in 90% of cases.
