We have a model of a human heart and a human brain. I have a heart disorder, my friend has a brain disorder. We have a lot in common, we both have a serious problem with a major organ. You cant live without a heart, you can't live without a brain. So you see it really makes no sense to discriminate and stigmatize people with brain disorders because they are no different than people with heart disorders.
Mental illnesses are brain disorders.
Mental illness is a very real medical disorder. It affects millions of people in the United States each year. Yet as common as it is, it is also misunderstood, and many times not recognized. Mental illness is a biological brain disease which interferes with normal brain chemistry. Genetic factors may create a predisposition in some people, and life stresses may trigger the onset of symptoms.
