title: Clinical and electroencephalographic characteristics of benign occipital epilepsy of childhood in two tertiary Brazilian hospitals.
abstract: This study intended to investigate the clinical and electroencephalographic benign occipital epilepsy of childhood (BOEC) characteristics in a population sample of patients from two tertiary Brazilian hospitals. We analyzed retrospectively 4912 electroencephalograms (EEGs) records, and the included patients were submitted to a new clinical and EEG evaluation. Were included 12 (0.92%) patients; 4 (33.3%) with criteria for early BOEC; 6 (50%) for late form and 2 (16.7%) with superimposed early and late onset forms. After new investigation, 2 (16.7%) had normal EEG; 4 (33.3%) had paroxysms over the occipital region; 3 (25%) over the temporal posterior regions and 3 (25%) over the posterior regions. Sharp waves were the predominant change, occurring in 8 (66.6%); spike and slow wave complexes in 1 (8.3%) and sharp and slow wave complexes in 1 (8.3%). Vomiting, headache and visual hallucinations were the most common ictal manifestations, presented in 100% of patients with superimposed forms. Vomiting were absent in the late form and headache was present in all forms of BOEC.
