Several lines of research have linked olfactory regions with the pathophysiology of focal
epilepsies. Among those regions, the piriform cortex represents the major part of the primary
olfactory cortex. According to these data, we raised the hypothesis that in patients with
mesial temporal lobe epilepsy associated with hippocampal sclerosis exists an interictal
dysfunction of olfactory processing that could be more significant compared to patients with
extra‐hippocampal focal epilepsy and healthy controls. This could be the consequence of a …
