Schizophrenia is a severe neuropsychiatric disorder that affects around 0.5 – 1% of the population. It occurs when the parts of the brain responsible for emotion and sensation stop working properly. The illness can develop slowly and a person may stop living their normal life, withdrawing from people, losing interest in things and possibly having angry outbursts.
You can find further information on symptoms of Schizophrenia, how it is diagnosed, and treatments from the UK patient organisation Rethink Mental Illness.
