Abstract

IVAROLA, Paula et al. Benefit of surgery in a case of negative motor focal epileptic seizures secondary to parietal cortical dysplasia. Medicina (B. Aires) [online]. 2023, vol.83, n.6, pp.1013-1017. ISSN 0025-7680.

Focal atonic seizures are recognized rarely as ictal phenomena, they can correspond to both generalized epilepsy and focal epilepsy. The areas of the brain in volved in the management of this type of seizure are: the negative motor area and the primary motor and primary somatosensory cortices, although the neurophysiology that generates them is still unclear. We present the case of a patient with focal atonic seizures in the left upper limb, refractory to drug treatment. Neuroimaging was performed, a parietal cortical lesion was diagnosed. A scalp Video EEG and then a Stereo EEG was performed, defining the epileptogenic area and its relationship with eloquent areas. Surgical resection of the lesion was performed, achieving complete seizure control.
