Abstract:
We analysed the influence of mesial temporal lobe epilepsy on the thickness of the corpus callosum (CC) in a large sample of well-characterized patients (n=96) and healthy controls (n= 28). In particular, we investigated whether callosal structures are differentially affected depending on the affected hemisphere and age of epilepsy onset.Overall, we observed that epilepsy is associated with a decreased thickness in posterior callosal regions. Patients with an early onset, especially patients with left onset, additionally exhibited a smaller callosal thickness in more anterior andmidbody regions.These findingsmay reflect non-specific as well as specific effects of temporal lobe epilepsy on CC development and interhemispheric connectivity.
