10. Prognosis for Tay-Sachs Disease

In infantile and juvenile Tay-Sachs disease, the prognosis is poor. Young bodies are incapable of recovering from damage done by the cellular degeneration. As a result, death usually occurs in those with infantile Tay-Sachs by age four; with the juvenile form, usually by age 15. Late-onset Tay-Sachs comes with a more favorable prognosis. There is a significantly increased risk of psychosis and muscle impairment. However, life expectancy may not decrease because of the disease.
