Brain Donation

Brain donation gives researchers the tissue they need to understand and treat dementia; learn who can donate, how to arrange it in advance, what it costs, and what families can expect.

Last reviewed: October 2026

Much of what we know about Alzheimer's and other dementias came from studying donated brains. Brain tissue lets researchers see plaques, tangles, blood vessel damage and other changes directly, and compare them with how the person thought and behaved in life. It remains one of the most valuable gifts anyone can give to dementia research.

Why brain donation matters

• It confirms the diagnosis. Even with today's scans and blood tests, the only way to be completely sure what caused someone's dementia is to examine the brain after death. Many people turn out to have more than one cause, such as Alzheimer's plus small strokes or Lewy bodies (see Mixed Dementia).
• It drives new treatments. Researchers use tissue to find new drug targets and test ideas. Studies of donated brains helped show that amyloid and tau build up years before symptoms (see Amyloid and Tau Explained).
• Healthy brains are needed too. To understand disease, scientists must compare it with brains from people who didn't have dementia. Donors without brain disease are in short supply.
• It can help families. Many programs share a report of the findings with the family, which can bring answers and may matter for relatives' own risk, for example in Frontotemporal Dementia or Young-Onset Dementia.

Who can donate?

In general, adults with or without a brain disease can register. Programs especially welcome people with a diagnosis of a neurological condition and people with healthy brains. Each program has its own rules, and some may not be able to accept every donation, for example because of certain infections or the timing and location of death.

Brain donation is separate from organ donation for transplant. Being an organ donor on your driver's license does not cover brain donation for research. It has to be arranged separately.

How to arrange it: plan ahead

Brain donation works best when it's arranged well before death, because the brain needs to be recovered within hours, usually within about 24 hours. Arranging it in a crisis is very hard.

Steps:

1. Talk with your family. The next of kin usually has to give final consent at the time of death, so make sure they know and agree.
2. Register with a program. Options in the U.S. include:
3. The NIH NeuroBioBank, a network of brain banks funded by the National Institutes of Health that collects and distributes tissue to researchers.
4. Alzheimer's Disease Research Centers (ADRCs). These NIH-funded centers at universities around the country often run brain donation programs, especially for people taking part in their studies.
5. The Brain Donor Project, a nonprofit that helps people sign up and connects them with the NIH NeuroBioBank.
6. Fill out the paperwork, which usually includes consent forms and some medical history.
7. Tell your doctors, hospice team, and funeral home so they know what to do and whom to call.
8. Keep the program's 24-hour phone number where family and caregivers can find it, such as with your advance directive (see Planning Your Future Care).

Common questions

Does it cost the family anything? Programs generally cover the costs of recovering the brain. Families still pay for funeral arrangements as usual. Ask the program exactly what's covered.

Will it affect the funeral? The brain is removed through an incision at the back of the head that is not visible. An open-casket viewing is still possible, and the funeral usually doesn't need to be delayed.

Do religious traditions allow it? Many faiths support donation as an act of generosity. If you're unsure, talk with your faith leader.

Will we get results? Many programs offer a written report on the diagnosis to the family, often several months later. Ask when you register.

Can I change my mind? Yes. You can withdraw at any time.

Is my information private? Tissue is coded and shared with researchers without names, under strict privacy rules.

A conversation worth having

Talking about brain donation can feel uncomfortable. Many families say it gave meaning to a hard loss: something good, and lasting, came from it. If you or someone you love is living with dementia, or if you simply want to help future generations, consider raising it alongside other end-of-life plans.
