What is the typical prognosis interval after Huntington's disease onset?

Explanation:
The typical course after Huntington's disease symptoms begin lasts about 15 to 20 years. This reflects long-term studies showing median survival from onset in that range, with considerable variation between individuals. A shorter timeframe like 5–10 years underestimates the course for many patients, while 30–40 years is longer than what is usually observed. Describing it as a lifetime with only minor progression ignores the progressive, ultimately disabling and fatal nature of the disease. So, 15–20 years is the best fit.
