TREVISOL-BITTENCOURT, PAULO C. and TROIANO, ANDRÉ R.. Interictal personality syndrome in temporal lobe epilepsy: case report. Arq. Neuro-Psiquiatr. [online]. 2000, vol.58, n.2B, pp. 548-555. ISSN 0004-282X. http://dx.doi.org/10.1590/S0004-282X2000000300024.
The syndrome of interictal personality in non-dominant temporal lobe epilepsy consists of hyposexuality, hyperreligiosity, humorlessness and hypergraphia. Its notification, in 1974, was followed by an extensive search for these traits in broad epileptic populations. Nevertheless, these statistical studies failed to match this syndrome in general temporal lobe epileptics, and its existence became then target of doubt. We report the case of a 35 year-old man presenting partial complex epilepsy, whose singularity lies in his sophisticated drawing abilities. The large amount of buildings and houses he paints expresses his hypergraphia. He also presents hyposexuality and hyperreligiosity. MRI shows right mesial temporal sclerosis. Temporal hyperconnection, caused by a basal temporal irritative focus, is the most probable pathophysiological mechanism. Epileptic fits can be controlled in the majority of cases. However, behavioural symptoms usually do not respond to pharmacological approach or psychotherapy.
