[EEG topography in HIV-positive hemophiliacs]

HIV-central nervous system manifestations, here the AIDS-Dementia complex, are at the moment of special interest owing to its unexpected development. With EEG-topography one can expect to gain more information about possible changes in frequency according to topographical location. We recorded 69 HIV-positive hemophiliacs (23 WR 2, 26 WR 3-5 and 6 patients) plus 50 HIV-seronegative controls with a 12 channel EEG-topography evaluation. During the critical examination we looked for the results of two parameters: a) alpha 1-3/alpha 4 and b) alpha 4-4/9. In comparison to the control group we found a statistical significance (p less than 0.05) for WR 2-6 in alpha 1-3/alpha 4 index. Concerning the alpha 1-4/9 index one can only recognize a statistical significance (p less than 0.05) for WR 3-6 patients in comparison to the controls.
