Schizophrenia
Schizophrenia is a serious brain disorder. It is a disease that makes it difficult for a person to tell the difference between real and unreal experiences, to think logically, to have normal emotional responses to other, and to behave normally in social situations. People with schizophrenia may also have difficulty in remembering, talking, and behaving appropriately. Schizophrenia is one of the most common mental illnesses.
About 1% of the world population has schizophrenia. In the United States, there are about 2.5 million people with the disease. Schizophrenia is the cause of more hospitalizations than almost any other illness. Schizophrenia most commonly begins between the ages of 15 and 25.

Dropping out of school or doing badly at work are other early signs of schizophrenia. As the illness progresses, symptoms of psychosis develop. The person starts to act strangely and talk nonsensically. People with schizophrenia may develop paranoid delusions. Examples of this would be that they might see, feel, smell, or hear things that are not really there. They may have physical symptoms, like frowning or unusual movements, and may stand or sit in strange positions. Some people become almost motionless. Others move around constantly. The severity of symptoms will vary from one person to another. The symptoms also tend to worsen and improve. When the symptoms are improved, the person may appear to behave relatively normally, but usually there will be repeated episodes of the illness that will cause symptoms to reappear.
