Schizophrenia is a chronic and severe disorder that affects how a person thinks, feels, and acts. Although schizophrenia is not as common as other mental disorders, it can be very disabling. Approximately 7 or 8 individuals out of 1,000 will have schizophrenia in their lifetime. People with the disorder may hear voices or see things that aren’t there. They may believe other people are reading their minds, controlling their thoughts, or plotting to harm them. This can be scary and upsetting to people with the illness and make them withdrawn or extremely agitated. It can also be scary and upsetting to the people around them. People with schizophrenia may sometimes talk about strange or unusual ideas, which can make it difficult to carry on a conversation. They may sit for hours without moving or talking. Sometimes people with schizophrenia seem perfectly fine until they talk about what they are really thinking.
