The cessation of continuous spike wave in slow-wave sleep following a temporal lobectomy

The role of surgery in continuous spike wave in slow-wave sleep has not been robustly explored. The authors present a case of an 11-year-old boy with refractory partial seizures and continuous spike wave in slow-wave sleep who was treated with an anterior temporal lobectomy. His presurgical brain magnetic resonance imaging revealed right basal ganglia and thalamic infarcts and right mesial temporal sclerosis. Following surgery, he achieved seizure freedom, cessation of continuous spike wave in slow-wave sleep, and improved cognition. This case provides further evidence that epilepsy syndromes with generalized electrographic discharges can be secondary to focal pathology and potentially cured with resective surgery. The normalization of his sleep electroencephalogram following the anterior temporal lobectomy suggests that temporal lobe structures may be involved in the seizure network needed to generate continuous spike wave in slow-wave sleep.
