Abnormal cortical sources of resting state electroencephalographic rhythms in single treatment-naïve HIV individuals: A statistical z -score index

Highlights • This pilot study tested a statistical z -score procedure to identify single treatment-naïve HIV individuals having abnormal resting state electroencephalographic (EEG) sources. • Compared to HIV individuals with normal EEG sources, those (47.6%) with abnormal z -score values showed wors...

Description
Summary:Highlights • This pilot study tested a statistical z -score procedure to identify single treatment-naïve HIV individuals having abnormal resting state electroencephalographic (EEG) sources. • Compared to HIV individuals with normal EEG sources, those (47.6%) with abnormal z -score values showed worse cognitive and serological markers. • This procedure is promising to assess effects of HIV on brain function in single treatment-naïve HIV individuals.
