13 Early Warning Signs & Symptoms of ALS (Amyotrophic Lateral Sclerosis)

8. Dyspnea

Dyspnea, Signs and Symptoms of Amyotrophic Lateral Sclerosis (ALS)

Typically, patients with ALS experience a progressive decrease in vital lung capacity due to a significant weakening of the chest muscles and diaphragm. Virtually all patients with ALS will ultimately experience shortness of breath when walking, or during rest, difficulty or inability to lie in bed and maintain respiratory capacity, a weakened cough reflex, and a severe inability to clear their throat and pulmonary secretions.

The development of dyspnea can be considered a turning point in the disease’s evolution since the vast majority of ALS patients die of respiratory failure.
