Older age, bulbar onset, and faster disease progression were associated with weight loss \u2265 10% at diagnosis. Among 132 patients, 72% experienced death or tracheostomy, with a median survival of 34 months. Survival was notably reduced in patients aged \u2265 60 years, those with significant weight loss, rapid disease progression, or those submitted to gastrostomy. Weight loss and the rate of disease progression were the strongest predictors of reduced survival.
