Mental illness runs in families and usually close relatives of persons with mental illness are more likely to develop the disease than those who are not related to someone with the illness. For example, according to the National Institute of Mental Health, the risk of inheriting schizophrenia is 10% in individuals who have one immediate family member with the disease and 40% if the disease affects both parents or an identical twin. Schizophrenia, depression and bipolar disorder are among the nation's top ten leading causes of disabilities. Other factors that play a role in mental illness include environmental stress, abnormalities in the brain, or chemical defects.

"The good news is that although genetics is a major factor, it does not mean that a person will automatically develop mental illness," said Gwen Skinner, Director for the Georgia Division of Mental Health, Developmental Disabilities and Addictive Diseases. "It just means that a person is more likely to get the condition than if they didn't have an affected family member."

Understanding the genetic link to mental illness and signs to look for can help families manage problems associated with mental health problems.

Much progress has been made in the last two decades in treating mental illnesses. As a result, many mental conditions can be effectively treated with one or a combination of medication and counseling. When diagnosed early and treated properly, many people recover from their illness and are able to live full and productive lives. Studies show that as many as 8 in 10 people suffering from a mental illness can effectively return to their normal activities if they receive appropriate treatment.
