Panic attack symptoms in a patient with left temporal lobe epilepsy.

We describe a 56-year-old woman with left temporal lobe epilepsy who developed symptoms of a panic attack. Owing to normal electroencephalography and brain magnetic resonance imaging results, she was initially diagnosed as suffering from panic attacks and treated for anxiety neurosis. The symptoms persisted and she was re-examined in our department. An interictal electroencephalogram showed paroxysmal spike waves in the left mesial temporal lobe region and this was the basis for a diagnosis of left temporal lobe epilepsy. This report suggests that left temporal lobe epilepsy should be considered as the differential diagnosis when patients frequently complain of fear or anxiety.
