Bill Gates, the billionaire philanthropist, is pouring $10 million into an Alzheimer’s Association program called Part the Cloud, which the agency calls “high-risk, high-reward” Alzheimer’s and dementia research involving new drugs, diagnostics, and ways of tracking brain activity.

Gates’ award to Part the Cloud, which is led by fellow philanthropist Mikey Hoag, is on top of $20 million that the Alzheimer’s Association is raising for the effort..

According to researchers, Part the Cloud’s focus is less on late-stage Alzheimer’s drugs that have a poor track record, and more on early-stage clinical studies of new avenues of tackling dementia.
