Schizophrenia is a chronic, severe, and disabling brain disorder that
affects about 1 percent of the population during their lifetime. Symptoms
include hallucinations, delusions, disordered thinking, and social
withdrawal. Schizophrenia appears to be extremely rare in children; more
typically, the illness emerges in late adolescence or early adulthood.
However, research studies are revealing that various cognitive and social
impairments may be evident early in children who later develop
schizophrenia. These and other findings may lead to the development of
preventive interventions for children.
Only in this decade have researchers begun to make significant headway
in understanding the origins of schizophrenia. In the emerging picture,
genetic factors, which confer susceptibility to schizophrenia, appear to
combine with other factors early in life to interfere with normal brain
development. These developmental disturbances eventually appear as
symptoms of schizophrenia many years later, typically during adolescence
or young adulthood. A number of new, effective medications for
schizophrenia have been introduced during the past decade.
