Hillary Clinton announced on Tuesday her decade-long plans to find a cure for Alzheimer's disease. She is proposing an annual $2 billion budget, almost double of the approved 2016 allocation for Alzheimer's research and support services of $886 million, per Reuters.

"We owe it to the millions of families who stay up at night worrying about their loved ones afflicted by this terrible disease and facing the hard reality of the long goodbye to make research investments that will prevent, effectively treat and make a cure possible by 2025," Clinton said in a statement in Fairfield, Iowa.

Alzheimer's is a form of dementia that causes problems with behaviour, memory and thinking that affects people aged 65 and above, but some can have younger-onset in their 40s or 50s, per ALZ.org. About five million Americans suffer from the disease with the median age rising, and the cases are expected to grow to nearly 15 million by 2050.

It is the sixth leading cause of death in the U.S. and being the only one in the top 10 with no treatment or cure. Alzheimer's does not only affect the ones who have it, but family members have to carry the burden of taking care for them.

Many have to choose between their jobs and caring for their loved ones while many a lot suffers from emotional and physical health problems as a result of their responsibilities for those who have the disease. Clinton has used the story of New Hampshire librarian, Keith F. Thompson and his 84-year-old mother with Alzheimer's.

Thompson can't afford full-time care for her mother so he brings her along to his work. "He's just praying that she will be able to continue to manage that experience every day because he doesn't know what happens next," Clinton said.

According to the New York Times, the former Secretary of State' plans is just not about finding a cure, but also how to save money as Alzheimer's is one of the most expensive for the health care system. She was also the first presidential candidate to have a full-fledged plan to combat Alzheimer's although Republican Jeb Bush has spoken about his mother-in-law's dementia.

Clinton served as a co-chairwoman of the Congressional Task Force on Alzheimer's disease when she was a senator for New York. Virginia Sen. Mark Warner praised the proposal saying that the cure is within reach. Republican and former speaker of the House, Newt Gingrich wrote on Twitter, "I often disagree with Hillary Clinton, but on Alzheimer's she is moving in the right direction."
