A common problem associated with schizophrenia is the lack of insight into the condition itself. This is not a willful denial but rather a part of the mental illness itself. Such a lack of understanding, of course, poses many challenges for loved ones seeking better care for the person with schizophrenia. What are the causes of schizophrenia? Researchers still do not know the specific causes of schizophrenia. Research has shown that in certain types of schizophrenia, a CT scan of the brain is anomalous with non-schizophrenics. Like many other illnesses, schizophrenia seems to be caused by a combination of genetic vulnerability and environmental factors that occur during a persons development. Recent research has identified genes that appear to increase risk for schizophrenia. These genes only increase the chances of becoming ill; they alone do not cause the illness. Research has shown a significant increase in risk of developing schizophrenia when one or both parents or sibling(s) has been diagnosed. Mental Health Concerns190'
