Relationship between environmental factors and gray matter atrophy in refractory MTLE

Abstract

The more widespread structural voxel-based morphometry abnormalities and worse IQ performance identified in the negative-family history (FH) group may result from a stronger environmental influence, including initial precipitating injuries. This is further support for the hypothesis that hippocampal sclerosis in mesial temporal lobe epilepsy with positive FH is determined by a stronger genetic predisposition with less influence of environmental factors compared with patients in the negative-FH group.
