Guide To Primary Lateral Sclerosis Symptoms

Slurred Speech

Patients with PLS may have slurred speech. Their rate of speaking may also be reduced. Oftentimes, these symptoms go hand in hand with a hoarse or low voice. Individuals with primary lateral sclerosis may also drool. Slurring and drooling are caused by a weakening of the facial muscles. As the muscles weaken, patients have a harder time controlling their movements and speaking clearly.

It's important to note the disease's average progression takes place over about twenty years. Some patients' slurring may become slowly worse as the facial muscles continue to weaken. Slurred speech can also be a serious sign of other neurological problems including Parkinson's disease, ALS, or a stroke.
