Which type of condition is defined as a disease that develops and continues over a prolonged period of time?

I believe the answer is (ALS) Lou Gerrigs disease. Usually, with this process is a neuro-muscular disease. patient's can suffer it's complications 4 7-10 yrs. the end result is usually patient looses function of the diaphragm muscles that lead to suffocation.
