It seems likely that more than one gene may be involved. There is some evidence that schizophrenia may be associated with interference with early brain development, possibly as a result of viral infections or malnutrition during pregnancy. Birth difficulties may increase the risk of developing schizophrenia. Whatever the cause of schizophrenia, the disorder is often precipitated by adverse life events such as the break-up of a relationship, loss of a job or a bereavement. Alcohol and drug misuse may also be precipitating factors.
Some sufferers experience negative symptoms such as blunted emotions, social withdrawal and apathy.
The positive symptoms respond more readily to treatment. This causes mood swings between mania and depression and the illness can be devastating. Public awareness Examine your own attitude to mental illness. If you and your staff provide a sympathetic approach then people with mental health problems and those who care for them will be more able to ask your advice. Display leaflets about mental illness, and about local services and support groups in your pharmacy.
