The Influence of Age:
Under 40 at Onset: More than 50% of patients live beyond 5 years, and a significant subset exceeds 10 years.
Over 65 at Onset: Median survival drops to roughly 2 to 3 years.
Over 80 at Onset: Survival is often less than 2 years from diagnosis, with a higher rate of bulbar involvement.
