EARLY DIAGNOSIS OF SCHIZOPHRENIA
Abstract
Early diagnosis of schizophrenia is essential for improving long-term clinical outcomes, reducing disability, and enhancing quality of life. Schizophrenia often begins with subtle prodromal symptoms that precede the first psychotic episode. Identifying these early signs allows timely intervention. This paper discusses early symptoms, risk factors, diagnostic approaches, and modern strategies for early detection and management.
Keywords
Schizophrenia is a severe, chronic psychiatric disorder affecting approximately 1% of the global population. It is characterized by disturbances in thinking, perception, emotions, and behavior. Traditionally, diagnosis occurs after the first psychotic episode, but research shows that pathological changes begin much earlier. Early diagnosis focuses on identifying individuals in the prodromal or high-risk stage, enabling preventive strategies and early treatment interventions.
