Fragmented minds, part 2

Schizophrenia is caused by a complex range of genetic and environmental factors but it can seem to occur out of the blue. We hear from a father who first knew his son had schizophrenia when he found him curled up in his wardrobe, psychotic, frozen with fear. We find out about some of the early warning signs and how young people with schizophrenia can be helped to cope with the social isolation and impaired thinking abilities that result from this debilitating brain disorder.
