By Mayo Clinic staff

A temporal lobe seizure starts in the part of the brain that processes emotions, fight or flight reactions, and short-term memory. Many who have temporal lobe seizures may experience odd feelings — ranging from euphoria to fear, deja vu, and hallucinations of taste or smell — at the onset of their seizures.

Seizures beginning in the temporal lobes may stem from an anatomical defect or scar. But, it's not always possible to determine the cause of a temporal lobe seizure.

Temporal lobe seizures are often resistant to anti-seizure medications. Surgery may be an option for some people if their seizures consistently begin in only one of their two temporal lobes. Many become free of temporal lobe seizures when the affected portion of the lobe is removed.
