[Atypical evolution of benign partial epilepsy in children].

Idiopathic localization-related epilepsies are summarized according to the current classification of the International League Against Epilepsy. The recognition of a distinctive idiopathic epileptic syndrome occurring in children and featuring ictal vomiting, partial motor seizures, and occipital spikes is emphasized. Atypical evolutions of benign partial epilepsy of childhood and status of BPECS. Acquired epileptic aphasia has also been correlated to BPECS, and all these syndrome (CSWS). Childhood epilepsy with occipital paroxysms may also evolve into CSWS and into clinical and EEG status. Differential diagnosis of BPECS includes children with fortuitous associations of BPECS with cerebral palsy and the occurrence of a clinicoelectroencephalographic phenotype of BPECS in children with progressive and nonprogressive structural brain pathologies. Childhood epilepsy with occipital paroxysms should be differentiated from cerebrovascular abnormalities mitochondrial myophathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS), and the syndrome of posterior cerebral calcifications, epilepsy, and celiac disease.
