"Diseases of the Brain"

I really do believe that personal issues like depression and addiction are "diseases of the brain". I believe that a person does not choose to develop issues like these. No one wants to be addicted to alcohol or drugs and nobody wants to be depressed. They may make a decision that leads them down that road, yet once they are on it, I believe that all control is lost. My uncle was an alcoholic. Yes, he chose to drink, yet after a certain point, he lost all control. Alcohol consumed his life, and although he tried everything to stop, he just couldn't. His body got so use to it, and after awhile, it became a disease, something that was always with him, even though he didn't want it.
