Schizophrenia is a chronic, severe, and disabling brain disorder. 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 These experiences can make them fearful and withdrawn and cause difficulties when they try to have relationships with others.Symptoms usually develop in men in their late teens or early twenties and women in the twenties and thirties, but in rare cases, can appear in childhood. They can include hallucinations, delusions, disordered thinking, movement disorders, flat affect, social withdrawal, and cognitive deficits.Schizophrenia is believed to result from a combination of environmental and genetic factors. People with schizophrenia are not especially prone to violence and often prefer to be left alone.So we shouldnt be afraid of them;moreover, we should help to socialise them.
