Since the lesion responsible for epilepsy in SWS is focal, the majority of seizures are focal seizures. In a study of 76 patients, Bebin and Gomez reported partial seizures in 35 patients (46%), generalized seizures in 15 of them (20%), and both in 26 of them (34%). [37]

Pascual-Castroviejo et al reported seizures in 32 (80%) of 40 patients with SWS; 22 (69%) of them had focal seizures contralateral to the PWS, with subsequent generalization in 6 patients; 8 patients (25%) had generalized seizures at onset, and infantile spasms occurred in 2 patients (6%). [39]
