What is Schizophrenia?

Schizophrenia is a chronic, severe, and disabling brain disorder that affects about 1 percent of people all over the world. People with schizophrenia sometimes hear voices others don't hear, believe that others are broadcasting their thoughts to the world, or become convinced that others are plotting to harm them. These experiences can make them fearful and withdrawn and cause difficulties when they try to have relationships with others.
