Schizophrenia is a chronic brain disorder that affects less than one percent of the U.S. population. When schizophrenia is active, symptoms can include delusions, hallucinations, disorganized speech, trouble with thinking and lack of motivation. However, with treatment, most symptoms of schizophrenia will greatly improve and the likelihood of a recurrence can be diminished.

While there is no cure for schizophrenia, research is leading to innovative and safer treatments. Experts also continue to unravel the causes of the disease by studying genetics, conducting behavioral research, and using advanced imaging to look at the brain’s structure and function. These approaches hold the promise of new, and more effective therapies.

The complexity of schizophrenia may help explain why there are misconceptions about the disease. Despite the origin of the word, from the Latin meaning "split mind," schizophrenia does not mean split personality or multiple personality. Most people with schizophrenia are not any more dangerous or violent than people in the general population and may, in fact, be more vulnerable to being the victims of crimes. While limited mental health resources in the community may lead to homelessness and frequent hospitalizations, it is a misconception that people with schizophrenia end up homeless or living in hospitals. Most people with schizophrenia live with their family, in group homes or on their own.

Research has shown that schizophrenia affects men and women fairly equally but may have an earlier onset in males. Rates are similar around the world. People with schizophrenia are more likely to die younger than the general population, largely because of high rates of co-occurring medical conditions, such as heart disease and diabetes.
