What is Schizophrenia?
Schizophrenia is a severe mental disorder in which people interpret reality abnormally. Schizophrenia may result in some combination of hallucinations, delusions, and extremely disordered thinking and behavior that impairs daily functioning, and can be disabling. Schizophrenia is a chronic condition, requiring lifelong treatment.
What are the Symptoms of Schizophrenia?
Schizophrenia involves a range of problems with thinking (cognition), behavior or emotions. Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized speech, and reflect an impaired ability to function.
Symptoms may include:
- Delusions
These are false beliefs that are not based in reality. For example, you think that you're being harmed or harassed; certain gestures or comments are directed at you; you have exceptional ability or fame; another person is in love with you; or a major catastrophe is about to occur. Delusions occur in most people with schizophrenia.
- Hallucinations
These usually involve seeing or hearing things that don't exist. Yet for the person with schizophrenia, they have the full force and impact of a normal experience. Hallucinations can be in any of the senses, but hearing voices is the most common hallucination.
- Disorganized thinking (speech)
Disorganized thinking is inferred from disorganized speech. Effective communication can be impaired, and answers to questions may be partially or completely unrelated. Rarely, speech may include putting together meaningless words that can't be understood, sometimes known as word salad.
What Causes Schizophrenia?
It's not known what causes schizophrenia, but researchers believe that a combination of genetics, brain chemistry and environment contributes to development of the disorder. Problems with certain naturally occurring brain chemicals, including neurotransmitters called dopamine and glutamate, may contribute to schizophrenia. Neuroimaging studies show differences in the brain structure and central nervous system of people with schizophrenia. While researchers aren't certain about the significance of these changes, they indicate that schizophrenia is a brain disease.
Risk Factors associated with Schizophrenia
Although the precise cause of schizophrenia isn't known, certain factors seem to increase the risk of developing or triggering schizophrenia, including:
- Having a family history of schizophrenia
- Increased immune system activation, such as from inflammation or autoimmune diseases
- Older age of the father
- Some pregnancy and birth complications, such as malnutrition or exposure to toxins or viruses that may impact brain development
- Taking mind-altering (psychoactive or psychotropic) drugs during teen years and young adulthood
Various Treatments available for Schizophrenia
Schizophrenia requires lifelong treatment, even when symptoms have subsided. Treatment with medications and psychosocial therapy can help manage the condition. In some cases, hospitalization may be needed. A psychiatrist experienced in treating schizophrenia usually guides treatment. The treatment team also may include a psychologist, social worker, psychiatric nurse and possibly a case manager to coordinate care. The full-team approach may be available in clinics with expertise in schizophrenia treatment.
Most individuals with schizophrenia require some form of daily living support. Many communities have programs to help people with schizophrenia with jobs, housing, self-help groups and crisis situations. A case manager or someone on the treatment team can help find resources. With appropriate treatment, most people with schizophrenia can manage their illness.
