Direct care costs for treating Alzheimer’s disease are estimated to be $200 billion in 2012, a new report reveals. Fully $140 will be paid through the Medicare and Medicaid programs. While 800,000 Alzheimer’s sufferers live alone, most are being treated in a skilled nursing facility, assisted living, or by a family caregiver, according to “2012 Alzheimer’s Disease Facts and Figures” report from the Alzheimer’s Association. Private insurance accounts for less than one-quarter of the costs, the report states. Currently, 5.4 million Americans have Alzheimer’s disease, and that number is expected to jump 30% by 2025, and triple by 2050.
