YARMOUTH, Maine (NEWS CENTER) -- According to the Alzheimer's Association, the disease is the 6th leading cause of death in the country, and yet the only one in the top 10 without a cure or a form of prevention.

It's also a costly disease; one the U.S. spends $200-billion on treating per year.

Senator Susan Collins toured Bay Square in YarmouthWednesday, a senior living community with a center specifically for patients with Alzheimer's or Dementia.

Based on how much is spent on care, Senator Collins created a national Alzheimer's plan, gathering a panel of experts on the disease. That panel found that the nation currently invests about $500-million in research, but in order to gain any traction, $200-billion should be invested per year.

Collins says in response, Congress has agreed to a 5-year plan to eventually invest that much, starting with the budget approved last year: an additional $122-million approved for Alzheimer's research funding.With that plan, experts on the panel are setting a goal to find a cure by 2025.
