Shared hippocampal abnormalities in sporadic temporal lobe epilepsy patients and their siblings

Objective To examine the shared familial contribution to hippocampal and extrahippocampal morphological abnormalities in patients with sporadic temporal lobe epilepsy (TLE) and their unaffected siblings. Methods We collected clinical, electrophysiological, and T1‐weighted magnetic resonance imaging (MRI) data of 18 sporadic patients with TLE without lesions other than hippocampal sclerosis (12 right, 6 left), their 18 unaffected full siblings,...
