Grey Matters highlights Medicare GUIDE as dementia costs hit $818 billion

A new USC-led study says Alzheimer’s disease and related dementias will cost the U.S. an estimated $818 billion this year, with unpaid caregiving and lost quality of life driving much of the bill. Grey Matters says the new Medicare GUIDE program could help ease those costs by offering no-cost support, caregiver training and respite services.

Why it matters: - Dementia is now a major household and public-cost issue, not just a medical one. - The USC-led study says the burden lands heavily on patients, family caregivers and public programs like Medicare and Medicaid. - Grey Matters is pitching the new Medicare GUIDE benefit as a practical source of financial and caregiving relief.

What happened: - A new multi-year study led by the University of Southern California and published June 24, 2026 in Alzheimer's & Dementia: The Journal of the Alzheimer's Association estimates the U.S. cost of Alzheimer’s disease and related dementias at $818 billion this year. - Grey Matters Precision Brain Health Centers said the Medicare GUIDE program is designed to support people living with dementia and their caregivers. - Grey Matters said it is among the first in Florida and across the U.S. selected by the Centers for Medicare & Medicaid Services to participate in GUIDE.

The details: - The study estimates 5.7 million Americans are living with dementia, including 5.1 million age 65 and older. - Reduced quality of life for people with dementia accounts for the largest cost in the study at $320 billion. - Informal care partners face an additional $15 billion in quality-of-life losses tied to emotional and physical strain. - About 5.2 million people provide 6.8 billion hours of unpaid care to a family member or friend with dementia. - The value of that unpaid care totals $237 billion. - Long-term and medical care costs for people with dementia total $222 billion. - Medicare and Medicaid cover about 70% of those care costs, or $154 billion. - Patients and families pay about 20%, or $46 billion, out of pocket. - People with dementia and their care partners forgo $23 billion in annual earnings. - The National Council on Aging says about 80% of older Americans lack the financial resources or savings to cover long-term care. - The National Council on Aging says 48% of older adults do not know how to plan for those needs. - The National Council on Aging says only 37% of people who want at-home care have an active savings or investment strategy. - Grey Matters co-founder and CEO Debra Geihsler said affordability and support resources are the main concerns for most families dealing with cognitive decline. - Geihsler said many families feel there is no help or hope, and that help exists. - Grey Matters describes itself as one of the first primary care clinics in the United States focused solely on managing cognitive health and preventing cognitive decline. - The GUIDE Model offers care navigation, 24/7 access to a support line, caregiver training and education, respite services up to $2,500 annually, and connections to community resources. - The program is a no-cost Medicare benefit for people living with dementia and those who care for them. - Grey Matters says GUIDE is intended to help people remain in their homes and communities longer while improving quality of life and reducing Medicare and Medicaid spending.

Between the lines: - The study’s biggest costs are not only medical. They also include lost independence, unpaid labor and reduced earnings. - That makes caregiver support a financial issue as much as a family issue. - GUIDE appears aimed at the part of dementia care that often falls outside standard medical visits: navigation, training and respite.

What's next: - Grey Matters is expected to use GUIDE to expand caregiver support and community-based dementia services. - The broader test will be whether the program can reduce strain on families while delaying more expensive care settings. - More information about Grey Matters is available from the company.
