How long can someone live with ALS?

The survival time for patients with amyotrophic lateral sclerosis (ALS) varies among individuals. Generally, the average life expectancy after symptom onset is between 2 to 5 years, although some patients may survive for over a decade. ALS is a chronic neurological disorder characterized by progressive degeneration of motor nerve cells, leading to muscle weakness, atrophy, and declining abilities in speech, swallowing, and respiration. Because disease progression is closely related to symptomatic treatments and daily care, a patient's survival duration can be significantly influenced by these factors. Although the prognosis for ALS is generally poor, patients should not abandon treatment. Through various approaches such as medication, psychological therapy, and respiratory support, symptoms can be alleviated, quality of life improved, and survival time potentially extended.
