Bill Gates makes $100 million personal investment to fight Alzheimer's

Billionaire Microsoft co-founder Bill Gates is to invest $50 million in the Dementia Discovery Fund, a venture capital fund that brings together industry and government to seek treatments for the brain-wasting disease, Reuters reported.

The investment - a personal one and not part of Gates’ philanthropic Bill & Melinda Gates Foundation - will be followed by another $50 million in start-up ventures working in Alzheimer’s research, Gates said.

With rapidly rising numbers of people suffering from Alzheimer’s and other forms of dementia, the disease is taking a growing emotional and financial toll as people live longer, Gates told Reuters in an interview.

“It’s a huge problem, a growing problem, and the scale of the tragedy - even for the people who stay alive - is very high,” he said.

Alongside the $50 million investment in DDF and the additional $50 million planned for start-ups, Gates said he would like to award a grant to build a global dementia data platform. This would make it easier for researchers to look for patterns and identify new pathways for treatment, he said.
