Earlier onset of symptoms is linked to a worse prognosis. For children who exhibit symptoms between the ages of 2 and 4, death usually occurs by the age of 15 to 20 years. The cause of death is usually due to neurological complications, obstructive airway disease, and cardiac failure. If patients have minimal neurologic involvement, they may survive into their 50s or beyond.
