The authors studied the EEG alterations of AIDS, classifying them according to the background rhythm and the occurence of paroxysmal activities. Seventy three HIV carriers with and without complications were enrolled in this study and their CDC (Center for Disease Control) rating is as follows: One belonged to CDC II group, four to CDC III group and sixty eight to CDC IV group. The EEG alterations found in this study were classified according to this rationale: Grade 0 - Constituted by those cases with a background rhythm made up of a greater than 9 Hz posterior alpha. Grade Oa -The same as Grade 0 with assimetry of the cerebral electrical activity (ACEA). Grade 1 - Alpha rhythm between 8 and 9 Hz: or alpha rhythm greater than 9 Hz but with a previous EEG showing an alpha rhythm frequence at least 1 Hz higher than the current frequence; orbackground rhythm - posterior alpha - greater than 9 Hz associated with theta waves that are difficult lobe distinguished from those related to somnolence. Grade la - The same as Grade I with ACEA. Grade 2 - Alpha background rhythm associated with brief bursts of theta and/or diffuse and predominantly anterior delta not related to somnolence; or theta waves intermingled with the alpha rhythm; or beta background rhythm with a low voltage EEG. Grade 2a - The same as Grade 2 with ACEA. Grade 3 - Theta background rhythm associated or not with brief bursts of predominantly anterior delta; or beta background rhythm with a low voltage EEG associated with slow rhythms (theta and delta not associated with somnolence). Grade 3a - The same as Grade 3 with ACEA. Grade 4 - Delta background rhythm. Grade 4a - The same as Grade 4 with ACEA. Grade 5- Delta background rhythm associated with brief periods of cerebral electrical activity (CEA) supression. Grade 5a - The same as Grade 5 with ACEA. Grade 6- Supression of CEA associated with brief bursts of delta. Grade 6a - The same as Grade 6 with ACEA. Grade 7- Isoelectrical EEG.
