Some disorders are short-term and treatable, and their prognosis is not as lengthy. Rest and medication are the most common courses of action for these treatable cases to help the patient return to proper health. Many of the cases are long-term, and there is not as much of a set and defined prognosis. The course of action can include extensive counseling and therapy. There are many reasons that the long-term cases are harder to treat and these include these cases normally get worse over time, and medication or therapy could not work. In this case, many of the prognosis tracks are to help the patient and their family become more comfortable and understand what will happen.
