KANDA, Paulo Afonso Medeiros and CAMPOS, Carlos José Reis de. Sexual differences of visual attention in cryptogenic partial epilepsy. Arq. Neuro-Psiquiatr. [online]. 1994, vol.52, n.2, pp.144-148. ISSN 0004-282X. http://dx.doi.org/10.1590/S0004-282X1994000200002.
The performance in visual verbal and non-verbal attentional tests was studied in 14 male and 18 female control subjects and 33 patients with cryptogenic partial epilepsy. The epileptic group was formed of 17 men and 16 women with no evidence of brain damage in CT scan examinations. Interictal epileptiform activity was observed only unilaterally, either in the right (8 male, 8 female) or left (9 male, 8 female) temporal lobes. The performance of epileptic men in visual tests was similar to that of normal men. On the other hand, the performance of epileptic women was worse than that of normal women. These results seem in accordance with the literature that suggests mat visual attention in women depends on the functional integrity of both cerebral hemispheres. In men, verbal visual attention is suggested to occur in the left cerebral hemisphere while non-verbal processes, predominantly in the right cerebral hemisphere. Further studies are necessary for the understanding of these sexual differences in cerebral hemispheric asymmetry.
