Schizophrenia is a complex mental disorder marked by disturbances in thinking, perception, emotions, and behavior, with symptoms including hallucinations and delusions affecting about 1% of the global population. Diagnosis involves stringent criteria such as the DSM-5, requiring the presence of multiple symptoms that cause significant impairment. Treatment typically combines antipsychotic medications with psychosocial interventions to address both biological and social factors, emphasizing the need for tailored approaches to improve individual recovery outcomes.
