Guide To Primary Lateral Sclerosis Symptoms

Difficulty Swallowing And Breathing

Primary lateral sclerosis patients may experience difficulty swallowing and breathing in the disease's late stages. These symptoms tend to occur after PLS has progressed for several years, so they're not usually the first signs people have that something is wrong. While adult-onset primary lateral sclerosis doesn't appear to shorten a person's life expectancy, complications from the difficulties breathing can be potentially serious. PLS starts in the legs, but the symptoms can affect the muscles in the hands and around the base of the brain. Weakness in the face and neck is what leads to difficulty swallowing, otherwise known as dysphagia. Trouble breathing can sometimes be attributed to trouble controlling the muscles around the airway.
