Causes & Effects of Schizophrenia

Understanding Schizophrenia

Learn about Schizophrenia Treatment

Schizophrenia is a pervasive mental health condition that can include symptoms such as disruptions in thinking patterns, hallucinations, and delusions. When left untreated, schizophrenia can significantly affect one’s entire life in a negative way.

Often beginning in early adulthood, schizophrenia affects one’s thought process and concentration, causing him or her to feel like current events are not real or experience a disconnect from his or her body. These feelings can interrupt an individual’s everyday living patterns.

Schizophrenia is a complex condition that requires intensive therapy and continued treatment in order to become manageable. Thankfully, treatment is available for those who are affected by this mental illness.
