Treatment is an attempt to make a person better or feel better in the long run. Treatment may or may mot be an enjoyable thing. It may come in the form of medicine or exercise or hypnotherapy or shock therapy or an unusual or healthy diet or many other forms. A Cure is a treatment that will completely work to the point of the person no longer being sick. Most treatments are not cures. They are attempts at only feeling better.
