A child who has one parent with schizophrenia, for example, has about a 10 percent chance of developing the illness, compared with a one percent chance if neither parent has schizophrenia. Current research implicates abnormalities in both the brain's structure and biochemical activities. Imbalances in the chemical messenger dopamine, for example, may underlie some cases of schizophrenia. The good news is that more than 50 percent of those who have schizophrenia can work, live in the community or with their families, and enjoy friends if they receive continuous, appropriate treatment. Keep in mind that other psychotic disorders, such as those caused by drug use or exposure to toxins, can share many of these symptoms.
Antipsychotic medications help bring biochemical imbalances closer to normal.
The newer drugs may also be effective for symptoms such as social withdrawal, extreme apathy, and blunted emotional expression. More such drugs are being developed. After these symptoms are controlled, psychotherapy and self-help groups can assist people who have schizophrenia learn to develop social skills, cope with stress, identify early warning signs of relapse, and prolong periods of remission. In addition, support groups and family therapy can give loved ones a better understanding of the illness and help them provide the compassion and support that play an important role in recovery. It is by no means exhaustive, nor does it include the full range of symptoms and treatments.
