Bill Gates fighting against Alzheimer’s for father

As part of the "Brain Power" series on TODAY, special anchor Maria Shriver talked to Gates about his mission to solve the medical mystery of the chronic neurodegenerative disease, which causes a slow decline in memory, thinking and reasoning skills.

Alzheimer's hits close to home for Gates, who revealed for the first time that his father, 92-year-old Bill Gates Sr., suffers with the disease.

"More and more people are getting Alzheimer's, and it's a tragic disease," said Gates.

In 2017 alone, Americans spent $259 billion caring for loved ones with Alzheimer's and other dementias. Despite decades of research, the cause of the disease is still unknown and effective treatments still unavailable.

But Gates, who's donating $100 million of his own money to find a cure, is optimistic.

"I really believe that if we orchestrate the right resources, it's solvable," the tech mogul told Shriver.
