Olfactory Epileptic Auras Neurol 51:56-61, Acharya,V.,et al, 1998 See this aricle in Pubmed Article Abstract Olfactory sensations were of various types but unpleasant in only seven. Auras evolved to complex aorta;seizures(automotor,hypermotor,or dialeptic seizures)in 12 patients,with further evolution to generalized tonic-clonic seizures in three and aphasic seizures in one patient.The EEG focus was localized to the mesial temporal region in all.Ten patients had a mesial temporal tumor;in one patient,it extended to the superior temporal gyrus, and in another,the frontal lobe.The tumor involved only the amygdala in two patients and both amygdala and hippocampus in six;none had hippocampal involvement alone.Surgery was performed in nine patients.All except one with partial tumor resection had a seizure-free outcome.This patient also became seizure-free after repeat surgery to remove residual tumor tissue in the amygdala.Olfactory auras are not necessarily unpleasant.The amygdala is the most likely symptomatogenic zone of olfactory auras.Tumors are the commonest etiology;mesial temporal sclerosis is a relatively rare cause.
