Abstract

PRADO, G. Fernandes do; CARVALHO, L.B.C.; SILVA, A. Baptista da  and  LIMA, J.G.C.. EEG and dementia indicators in AIDS patients' Rorschach test. Arq. Neuro-Psiquiatr. [online]. 1994, vol.52, n.3, pp.314-319. ISSN 0004-282X.  https://doi.org/10.1590/S0004-282X1994000300005.

We studied the EEG and Rorschach test (RT) of nineteen AIDS patients and eight normal people in the same age group. Eight patients presented slow alpha rhythms (8 to 9 Hz); three, not-slow alpha rhythms (>9 to 13Hz); and eight, beta rhythms in background activity. Paroxystic activity, characterized by diffuse theta or delta waves, was present in eleven patients. We observed Oberholzer syndrome (organic dementia diagnosed by RT) in ten patients and Piotrowski syndrome (organic dementia diagnosed by RT) in eleven patients; six presented both. When considering only the group of AIDS patients, we did not observe a significant relation among slow alpha rhythm, not-slow alpha rhythm and the presence of paroxystic activity with the above-mentioned syndromes. AIDS patients with slow alpha rhythms showed a significantly greater number of Piotrowski syndrome dementia indicators when compared to normal individuals or those with slow alpha rhythms. We did not observe the same with Oberholzer syndrome.
