The mind is much more connected to the brain than previously believed, and psychology is actually a science because psychology is “brain therapy.” Cognitive Therapy actually produces measurable changes in the brain, in the same way that learning produces changes in the brain. Disorders such as depression, schizophrenia, and so on are problems of the brain. Cognitive Therapy (or perhaps any kind of therapy) is a therapy that influences the client to change his or her brain in a way that causes better functioning–happiness, peace, and so on. Obviously, major disorders cannot be changed by the client, but minor disorders can be changed in measurable ways (depression, for example).
At the same time, the brain is not the only organ in a human being. Many other systems exist that are all inter-related. In other words, the brain may not be the entire cause. Religion and spirituality argue that there are even spiritual causes for disorders some of the time. Nonetheless, this article puts the focus of disorders on the brain–something that humans can study, research, and perhaps in the future begin to change and improve.
