Criminal liability and epilepsy: a case report of a postictal attempted homicide from Tunisia.

Objective: Patients with epilepsy who have been charged with a serious offense may be referred by the courts for forensic psychiatric examination. A detailed psychiatric and neurological examination is often necessary to assist the courts in making the right decision, as exemplified in the current case presentation.

Method: The forensic case of a 30-year-old Tunisian male with temporal epilepsy who exhibited an inadequate response to the treatment is presented here. The patient attempted to kill his neighbor after a cluster of seizures, showing apparent postictal aggression. An antiepileptic treatment was introduced a few days after the person's detention and was followed by forensic psychiatric examination, but the latter was not done until three months afterwards.

Results: On forensic examination, the patient's thought processes were clear with no evidence of a thought disorder or psychosis. Both medical and psychiatric opinions stated that the attempted homicide was due to a postictal psychosis. The patient was transferred to a psychiatric facility for further management and was found not guilty by reason of insanity.

Conclusion: This case illustrates the difficulties that experts may encounter in establishing criminal liability after aggressive behavior associated with epilepsy. It highlights shortcomings in Tunisian law (and promptness of forensic psychiatric examination) that should be addressed to ensure fairness of the legal process.
