RESUMEN
Abu Bakr Muhammad Ibn Zakariya Al-Razi, also known as Rhazes, was a 10th-century Persian polymath who made significant contributions to medicine, philosophy, chemistry, and psychiatry. He is credited with founding the first psychiatric ward in Baghdad, highlighting the medical treatment of mental illnesses. His empirical and innovative approaches to clinical observation and experimentation laid the basis for modern evidence-based medicine. Al-Razi's comprehensive works, such as "The Comprehensive Book," profoundly influenced both Islamic and European medical practices, securing his legacy as a pivotal figure in medical history. Therefore, the primary objective of this narrative review is to revisit the remarkable contributions of Al-Razi in the field of psychiatry, specifically highlighting his role as the founder of the first psychiatric ward.
