As a rare subtype of delusional misidentification syndromes (DMSs), Fregoli Delusion involves the belief that two or more individuals are actually the same person disguised as another. In this case report, a 23-year-old male presents with Fregoli Delusion, self-inflicted harm, and a history of being kidnapped and abused. While the patient had abstained from alcohol and drugs for two years, neuroimaging revealed non-specific developmental anomalies, adding to the complexity of the clinical situation. Diagnoses and treatments are complicated by the coexistence of psychotic symptoms, mood dysregulation, and complex delusional constructs. A combination of antipsychotic medication and cognitive behavioural therapy is more effective in
treating schizophrenic patients. It is important to closely monitor this patient due to their history of non-adherence to their treatment plan and drug abuse. As a result of this situation, trauma-focused care and personalized interventions are necessary, as well as additional research to enhance the treatment of Fregoli Delusions resulting from this situation.
