Depression is a serious medical condition that is associated with symptoms such as melancholy, loss of pleasure, loss of energy, difficulty in concentrating, and suicidal thoughts.
Depression is both a brain disorder and a state of mind. The brain is unique—it is the only organ whose function we consciously experience because the brain is the organ of the mind.
Illnesses of the mind-brain affect tens of millions of people in the United States. Depression is by far the most prevalent, representing 99% of all mind-brain illness. (Schizophrenia and major psychotic illness represent the remaining 1%). The umbrella of depression encompasses Major Depressive Disorder and its related mood disorders including bipolar disorder, postpartum depression, post-traumatic stress syndrome, anxiety disorder and suicide.
HDRF chooses not to use the term “mental illness” to refer to disorders of the mind and brain. The term conjures up negative images in the popular imagination, propagates stigma, and is not scientifically accurate. Therefore, at HDRF we always refer to this area as “mind-brain illness.”
