Dysarthria is a speech issue. It has to do with muscular control that has been impaired by nerve damage. A lot of ALS patients have it as that is a neuromuscular disease. (DBF's step-dad has ALS and has the dysarthria as well. He also has swallowing issues too.).

A lot of the patient's from the rehab hospital I type for have this. I also had seen it quite often in the hospital when I was working there.
