Crises epilépticas geram impactos comportamentais e cognitivos em indivÃduos que sofrem de epilepsia. Uma das funções cognitivas que pode ser afetada pelas crises epilépticas é a memória declarativa. O objetivo do nosso estudo foi investigar funções cognitivas, especialmente a memória operacional emocional de pacientes com epilepsia temporal mesial unilateral e pacientes submetidos a lobectomia temporal mesial unilateral. Para investigar a memória operacional emocional foi utilizado um teste de reconhecimento de faces que pode recrutar simultaneamente o lobo frontal (memória operacional) e o lobo temporal mesial (memória emocional). Nossos resultados demonstram que o fator epilepsia compromete de forma significativa o desempenho no teste de memória emocional. Por outro lado, a remoção cirúrgica do foco epiléptico promoveu uma melhora na memória emocional desses pacientes, além de diminuir o número de crises.
Epileptic seizures generate cognitive and behavioral impacts in individuals who suffer from epilepsy. Declarative memory is one of the cognitive functions that can be affected by epileptic seizures. The main objective of this work was to investigate neurocognitive function, especially the emotional working memory of patients with unilateral mesial temporal lobe epilepsy, and that of patients submitted to unilateral mesial temporal lobectomy. A face recognition test that can simultaneously recruit the frontal lobe (working memory) and mesial temporal lobe (emotional memory) was used to investigate emotional working memory. Our findings showed that the epilepsy factor significantly compromised the performance in the emotional memory test. On the other hand, surgical removal of the epileptic focus promoted an improvement in the emotional working memory of these patients, in addition to the significantly decrease in the number of seizures.
