1. Schizophrenia

Schizophrenia is a severe psychotic disorder that profoundly disrupts an individual’s ability to think, feel, and perceive reality. Individuals with schizophrenia often experience hallucinations, delusions, and disorganized thinking, leading to significant social isolation.
Their inability to distinguish between reality and fantasy can cause major challenges in daily functioning and increase the risk of self-harm and suicide. It is a lifelong condition requiring ongoing treatment, including medication and therapy.
