Schizophrenia, a serious mental disorder that affects 1% of people worldwide, is one of the most common illnesses. This mental illness is marked by symptoms which can be categorized in three ways: positive, negative and cognitive. Delusions, delusional thinking, and a disorganized way of speaking and talking are positive symptoms. Negative symptoms are social withdrawal, a lack of emotion and reduced drive. Cognitive symptoms can include memory problems, difficulty paying attention and making decisions.

It is important to understand that the etiology for schizophrenia involves a complex combination of environmental, genetic and neurobiological influences. A family history has been shown to increase the risk of schizophrenia in individuals. The risk of schizophrenia can be increased by environmental factors like prenatal and postnatal complications, viruses, or substance abuse.

In general, schizophrenia is treated with a combination therapy and medication. Antipsychotic medication is commonly prescribed for positive symptoms. Mood stabilizers or antidepressants can be used to treat mood disorders. Cognitive-behavioral therapies, like cognitive therapy, are effective in helping individuals with schizophrenia to manage symptoms, improve social functioning, and better their occupational performance.

The etiology is complex, and includes a variety of genetic, neurobiological, and environmental factors. Although the cause of Schizophrenia is still not known, early treatment and comprehensive intervention can be used to help people with schizophrenia manage their symptoms.
