ABSTRACT
The aim of the study is to evaluate the correlation between subjective memory complaints and neuropsychological tests in the epilepsy population. We administered a Self Report Memory Questionnaire, based on possible everyday memory failures, two questionnaires on anxiety and depression and a battery of cognitive tests to 150 patients with epilepsy (n=100 with partial epilepsy, n=50 with idiopathic generalized epilepsy) and a control group (n=50). A discrepancy between the results of the memory questionnaire and the cognitive tests was found in the epilepsy patients: the Self Report Memory Questionnaire did not show any correlation with the psychological tests. The same discrepancy was not seen in the controls, where the memory questionnaire was related to two verbal memory tests. Furthermore, patients with epilepsy reported greater difficulties on the Self Report Memory Questionnaire than the controls (P < 0.05). It appeared that the tendency to overstate memory problems was mainly related to anxiety and depression, but was not connected with the type of epilepsy, nor with its duration (in years). Seizure frequency, on the other hand, seemed to greatly influence mood, which in turn is probably affect subjective memory perception.
