ABSTRACT

The somatosensory evoked potentials are diagnostic tests that provide objective measures of the function of the neurologic pathway studied. In epilepsy, for example, these tests have been studied with diverse results. In our study we did median nerve somatosensory evoked potentials in the first 12 hours after an epileptic spell and repeated the study 24 hours or more after the epileptic spell and we compared the following variables: N20 latency, N13-N20 interlatency, N20-P22 amplitude, N20-P22 morphology (monophasic versus biphasic). We performed the present study to 3 patients with epilepsy and 5 patients as a control group. The results were compared with a Student t test for paired groups in the postictal and interictal period and a Student t test to analize the variables between the patients with epilepsy in the postictal period and the control group, we considered a p ‹ 0.05 as statistically significant. Results: We didn’t find statistical significance for the following tendencies measured; N13-N20 interlatency and the N20-N30 interlatency in the right side between the groups with epilepsy in the postictal period and the healthy control group (p 0.146 and p 0.109 respectively). The lack of statistical significance may be in relation to the small number of patients analyzed. These results open the possibility for further investigations in a bigger number of patients.
