Schizophrenia (SKIT-suh-FREE-nee-uh) is a chronic, severe, and disabling mental disorder. People who have it may hear voices, see things that aren't there, or think that others are reading or controlling their minds. They have trouble thinking logically and expressing emotion. Treatments such as medications, when used regularly and as prescribed, can help reduce and control many symptoms.
