A Case of Complex Partial Seizures Presenting asAcute and Transient Psychotic Disorder

omplex partial seizures are focal (CPS) (i.e., start in one area of the brain) and associated with impairment inconsciousness. Most of them arise in the temporal region and are characterized by aura, impaired consciousness, and automatisms.CPS that arise in temporal region are most often misdiagnosed as primary psychiatric illness.Case Report.A25-year-oldmalepresented with fluctuations in consciousness, aggressive behaviour, hallucination, and delusions of grandeur lasting a few hours.He was diagnosed with acute and transient psychotic disorder according to ICD10 criteria and was treated with intramuscularhaloperidol 10mg BID followed by oral olanzapine 10mg. Computed tomography of brain and electroencephalogram werenormal. After 15 days he presented again to the outpatient department with complaints of aggressive behaviour and sensorymisinterpretations. Video electroencephalogram was recommended, which was not done due to financial constraints. The diagnosiswas reconsidered and he was started on oral carbamazepine due to high clinical suspicion, of complex partial seizures, in spite of lackof EEG evidence. He responded well to antiepileptic and symptom remission has maintained well.Conclusion. Patients presentingwith psychosis need careful diagnostic evaluation for other possibilities
