To know the frequency of Todd s paralysis during the video EEG
monitoring studies, to investigate in its pathophysiology, and to confirm its
value to localise the epileptic focus. PATIENTS AND METHODS: We reviewed 114
monitoring studies, in 102 patients. RESULTS: Sixty patients had epileptic
seizures. An obvious paresis was noted in four seizures of two patients (3 and 1,
respectively). Both patients had frontal epilepsy. During the paralysis, in the
first patient the EEG showed ictal discharges on the contralateral centrotemporal
area. In the second patient, the EEG demonstrated slow waves in the contralateral
frontal region. The ictal onset was contralateral to the paresis in all cases. No
patient with pseudoseizures had paralysis. CONCLUSIONS: Postconvulsive paralysis
are not frequent in video EEG monitoring studies. However, if present it points
out to a contralateral seizure onset. In our series it happened in patients with
frontal seizures. The EEG may help to clarify if it correspond to a true
postictal phenomenon or to a ictal paralysis.
