Gastaut type-idiopathic childhood occipital epilepsy and childhood absence epilepsy: a clinically significant association?
We report an unusual association between idiopathic occipital epilepsy and childhood absence epilepsy in 2 pediatric patients. At first clinical and electroencephalographic evaluation, the patients presented the peculiar signs of idiopathic occipital epilepsy Gastaut type: focal sensory visual seizures, migraine-like symptoms (only in one patient) and unilateral spike-wave discharges over occipital regions. Both children were treated with valproic acid and their seizures were rapidly controlled. After a seizure-free period, the patients presented typical absence with ictal electroencephalographies showing 3 cycles/s generalized and symmetrical spike-wave complexes. We discuss the possible association between these two epileptic syndromes and its common pathophysiological mechanisms.
