This market resolves to the percentage of people born this year (2025) who will have symptomatic Alzheimer's disease at the time of their death. Clarifications:

1. This counts all deaths with symptomatic Alzheimer's disease, whether or not Alzheimer's disease is the cause of death.

2. If a treatment for Alzheimer's is developed, this would not count people who are diagnosed with Alzheimer's disease, but who are either subsequently cured or whose symptoms are in remission at the time of their death.
