Self injurious behavior in temporal lobe epilepsy.

Self-injurious behavior (SIB) or self-mutilating behavior (SMB) is rare but can occur in temporal lobe epilepsy. Such a behavior during seizures is not usually recalled by patient. Here is a case with self mutilating behavior in left temporal lobe epilepsy, presented because of its rare manifestation and diagnostic dilemma. A 19 year old unmarried Muslim student presented to emergency with SMB, guilty rumination and a persecutory delusion. The patient was intermittently confused about place and time. In subsequent assessments, he was found harboring death wishes and suicidal ideation. He transiently had auditory hallucination and thought broadcasting. He episodically tried to harm himself by severely biting only his left ring finger. It was difficult to influence him during such episodes. EEG revealed left temporal lobe seizure. Diagnosis of 'Epilepsy and Organic Psychosis' was made. The patient responded well to Antiepileptic and Antipsychotic medications.
