ABSTRACT
Mesial temporal sclerosis (MTS) is one of the most common causes of treatment-resistant epilepsy, especially temporal lobe epilepsy (TLE). Various psychiatric symptoms are common with temporal lobe epilepsy. However, the least established symptoms were psychotic symptoms. Furthermore, treatment-resistant schizophrenia is a significant proportion of schizophrenia patients who have failed treatment with at least two different antipsychotics, resulting in poor outcomes and a significant negative impact on the patient's life. In our case report, psychotic symptoms and abnormal behaviors were explained by schizophrenia for more than 17 years in a 32-year-old female, while the diagnosis of temporal lobe epilepsy with mesial temporal sclerosis was missed, resulting in incomplete treatment, which led to a deterioration of her quality of life for years. This case aims to shed light on TLE rare manifestations and to discuss the proper investigations and treatment that might increase the quality of life of these patients. Underlining the necessity for more research in treatment-resistant schizophrenia, this unusual case underscores the importance of exploring the underlying biological, psychological, and social risk factors. It also emphasizes the need to focus additional attention on formulating proper investigation strategies for the susceptible patient population.
