Brain donation helps researchers study brain disorders, such as Alzheimer’s disease and related dementias, that affect millions of people. Learn about why people donate their brains, the process of brain donation, and how you can enroll to make this generous gift.

Our brains are amazing, intricate networks that help us think, love, and breathe. But sometimes things go awry and cause brain disorders, such as Alzheimer’s disease and related dementias. By studying the brains of people who have died — both those who had a brain disorder and those who were healthy during life — researchers learn more about how types of dementia affect the brain and how we might better treat and prevent them. Brain donation provides an opportunity to help researchers better understand these disorders, which can lead to improved treatments for future generations.

While many people think that signing up to be an organ donor includes donating their brain, the purpose and the process of brain donation are different. Rather than helping to keep others alive, such as with kidney donation, brain donation helps advance scientific research. One donated brain can make a huge impact, potentially providing information for hundreds of studies. But many brains are needed from diverse populations and ages to help researchers investigate the causes of disease and to develop more effective therapies that can then be applied broadly.

People choose to donate their brains after death for various reasons. For some, the primary motivation is to help scientists discover new treatments and preventions for disease. For others, the main goal is to have a positive impact on their community and future generations. Sometimes, family members want to know, for certain, whether their deceased loved one had Alzheimer’s disease or if something else caused the dementia. At present, it is still true that only by examining the brain after death under a microscope is a full diagnosis of Alzheimer’s or another disorder possible. When donating as part of a study that a person actively participated in while alive, or to the NIH NeuroBioBank, there is no cost to the family for the donation procedure or the autopsy report.

One significant benefit of brain donation often catches families by surprise, and that is a sense of solace. Despite losing a loved one, some are comforted by knowing that this action may have a broad, positive impact on public health and wellness in the years ahead.

I did not expect to benefit other than being better informed, but my participation in brain donation can help future generations.

Whatever the reasons, one thing is true for everyone: Brain donation is a generous gift. Researchers use donated brain tissue to study brain diseases that affect millions of people and include Alzheimer’s disease, Lewy body dementia, frontotemporal disorders, mixed dementia, Parkinson’s, and Huntington’s disease, as well as brain injuries such as trauma and stroke.

Researchers learn the most from the brains of people who have participated in studies while they’re still alive. This allows researchers to track changes in memory, thinking, language, and behavior over time and to gather information on environmental and biological factors. The more researchers know about a brain donor, the more they can learn about the relationships among cognitive test results, biomarkers such as blood tests and brain scans, and the changes detected in the donor brain tissue. All of this information helps them gain a better understanding of disease causes, progression, and treatment options. Ultimately, this knowledge will help researchers better target and test treatments in clinical trials.

Brain donation helps researchers study psychiatric and neurological disorders, which affect millions of people each year. Learn about why people donate their brains, the process of brain donation, and how you can sign up to make this generous gift. Your donation will help researchers understand the brain, find better treatments, and improve the lives and well-being of future generations.

Why donate your brain?

The human brain is the most complicated biological structure in the universe. This small organ, weighing only three pounds, is the seat of our intelligence. It helps us make sense of what we see, hear, and feel, and controls our movement and behavior. Sometimes parts of the brain may not work or communicate properly, and this can lead to mental disorders like depression, schizophrenia, bipolar disorder, and attention-deficit/hyperactivity disorder. Researchers have made incredible progress in understanding these disorders, but there are still many unanswered questions.

That’s where you can help. Brain donation provides an opportunity to help researchers better understand how to prevent, diagnose, treat, and cure disorders of the human brain for future generations. By studying the brains of people who have died — including people who had brain-based disorders and people who were healthy during life —researchers learn more about how the brain works and how we might better treat and prevent brain disorders. One donated brain can make a huge impact, potentially providing information for hundreds of studies.

Who can donate?

Anyone age 18 or older can choose to donate their brain after death. People younger than 18 can choose to donate their brain with consent from a legal guardian.

Researchers are interested in studying brains from healthy people and from people with known brain disorders. They are also interested in studying brains from people of different races and ethnicities, genders, geographic locations, and sexual orientations.

What is the National Institutes of Health (NIH) NeuroBioBank?

The NIH NeuroBioBank works with participating research centers to make brain samples available to researchers who are working to understand brain disorders. The NeuroBioBank coordinates researcher requests and distributes brain tissue and other resources, including medical records and clinical data (when available). Visit the NIH NeuroBioBank website to learn more about how to become a brain donor.

The NIH NeuroBioBank has partnered with a nonprofit organization called the Brain Donor Project to provide potential donors a user-friendly and simplified enrollment process.

How do I become a donor?

If you are considering brain donation, talk with your loved ones early in your decision-making process to make sure they know about and understand your wishes. Talking to family and friends early may reduce stress and misunderstanding at the time of donation. You will also need to choose someone you trust to help make sure that your donation happens according to your wishes when the time comes. To start the process of becoming a brain donor, for yourself or on behalf of another person:

1. Complete the Brain Donor Project preregistration form online. The form asks for donor information, including contact information, and information about gender, race, and ethnicity. The form also asks about any brain-related diagnoses the potential donor may have.
2. Choose whether you want to receive the rest of the registration forms by U.S. postal mail or by email.
3. Complete, sign, and return the consent and release forms that you receive from your assigned brain bank.

Potential donors should be aware that brain banks may not be able to accept every brain donation.

Brain donation is a tremendous gift to the future. It touches the lives of not only the donor but also their cherished family, the wider community, and the countless generations that follow. If you’re interested in helping to advance our understanding of brain disorders and how we might treat and prevent them, we invite you to explore the possibility of becoming a brain donor.

Anyone over age 18 may choose to donate their brain after death. A legal guardian must provide consent for those younger than 18. This includes people who have a brain disorder and those with healthy brains. In fact, both are needed for this important research. Donations from people without symptoms of brain disease provide all-important insights into what’s considered normal aging of the brain and certain brain mechanisms that may protect against disease. Put simply, healthy brains provide researchers with critical models for comparison in understanding what’s gone wrong in cases of disease.

Researchers also need brains from a diverse group of people representing, for example, different races and ethnicities, genders, geographic locations, and sexual orientations.

Potential donors should be aware that brain banks may not be able to accept every brain donation. Given the resources needed to carefully remove, assess, store, and distribute this precious tissue, researchers must prioritize which brains will be most valuable to advancing science. The following are high priority for researchers studying Alzheimer’s disease and related dementias:

• People with healthy brains, including both younger and older people
• Those who are Asian, Black/African American, Hispanic/Latino, Native American and/or Pacific Islander, including both healthy donors and those with dementia
• People diagnosed with non-Alzheimer’s dementias, such as Lewy body dementia and frontotemporal disorders
• People with early-onset Alzheimer’s disease
• Those with Down syndrome, who are at higher risk for Alzheimer’s disease
• People with a diagnosis of dementia who have a family history of dementia
• Participants in clinical trials and other research on Alzheimer’s disease and related dementias

The participation of diverse individuals in research and clinical trials can help researchers understand how dementia affects certain groups and why some communities are disproportionately affected by certain diseases. For example, research suggests that African Americans and Latinos have higher rates of dementia than whites or Asians. Yet, because these groups are underrepresented and understudied in research, there is little information about why this might be and how these diseases affect their communities. Including diverse participants in research helps scientists determine whether there are unique factors that may contribute to dementia and other brain disorders in specific populations.

Although decisions surrounding life and death matters are never easy topics to address, the best time to think about brain donation is now. If you are considering brain donation, talk with your family and friends early in your decision-making process. This may reduce stress and misunderstandings at the time of donation. The opinions of family, friends, spiritual leaders, and others in your community may be helpful as you decide whether donation is right for you.

If you decide to donate your brain, consider enrolling in a study soon to provide the most value to researchers and future generations. NIA-funded Alzheimer’s Disease Research Centers have brain donation programs for their study participants. Contact your nearest center to find out if you’re eligible to participate.

My mother believed in education and service to others. This is an opportunity for others who believe in their community, who believe in research, who have had an interaction with Alzheimer’s to donate. It's a final gift to those you’re leaving behind, participating in the study, knowing that you can be a part of the solution.

Another way to become a brain donor is to pre-register with the Brain Donor Project, a partner of the NIH NeuroBioBank. The NeuroBioBank coordinates researcher requests and distributes brain tissue to researchers working to advance the science of brain disease. Pre-registration is strongly recommended because brain recovery must be performed within 24 hours of the time of death. If the appropriate consent and release forms have not been processed in advance, it can jeopardize completion of the process in a timely manner.

The following are general steps in brain donation. Note though that the process may be different for particular study participants.

• Step 1: Enroll in a study or brain donation program and complete the consent form. Familiarize yourself with the brain donation process.
• Step 2: Talk to your family about your decision, share what you’ve learned, and agree upon the best point or points of contact.
• Step 3: At time of death, your points of contact should connect with the donation coordinator within 2 hours of death.
• Step 4: The donation center (or brain bank) arranges for transport of the body to the donation site.
• Step 5: The brain is removed and sent to a brain bank for autopsy.
• Step 6: The body is returned to the family for burial or cremation and related ceremonies.
• Step 7: A brain autopsy is performed and, if requested, a report made available to the family in 3 to 9 months.
• Step 8: Brain tissue is processed and preserved and made available to scientists for future research.

The brain donation center will coordinate and pay for the body’s transportation to a location, such as a medical facility, mortuary or funeral home, for the brain removal to take place. A specialist will carefully remove the brain through the back of the head in a way that does not affect a person’s appearance. The donor’s body is then returned to the family for funeral arrangements. It is important to restate: Brain donation does not affect the deceased’s appearance, so the family may still have an open casket viewing if they wish.

Once removed, the brain is sent to a brain bank. A specialist at the brain bank will perform an autopsy to determine whether the donor had a type of dementia or another brain disorder. Autopsies are important to understanding how diseases affect the structure and function of the brain and can help direct future research. If requested, the family will receive a summary of these findings, typically within 3 to 9 months. The report often provides some definitive answers to family members. In a person who died without a cognitive disorder, the findings are also summarized, and sometimes there may be disease markers in the brain that didn’t cause symptoms during life. These individuals are of special interest to researchers so they can learn why some individuals did not become ill despite having typical markers of a disease.

The brain is then carefully stored at the brain bank, which will distribute tissue samples to qualified researchers. Researchers must adhere to high standards set by funding organizations such as the NIH as well as their own institutions and gain approval in order to use these precious tissue samples for their investigations. Donor names and other identifiers are not included in information sent to researchers, and all distributed samples are coded to protect the donor and his or her family’s anonymity and privacy. Findings from these future research projects are not shared directly with families.

It is important to inform those involved with your end-of-life planning and care about your decision to donate your brain. You may want to include relatives, friends, doctors, and other health professionals to help ensure that everyone involved understands your wishes. Here are some tips:

• Talk with your family and friends about your plans for brain donation well in advance. Tell them your reasons for donating and share any educational materials you have received.
• Include brain donation wishes in your end-of-life arrangements, such as in medical advance directives and information for your funeral home.
• Make sure your designated family member(s) have the brain bank phone number so they can call within 2 hours after your death.

If your family members have questions, contact your study coordinator or brain donation center contact to help address their concerns.

[My mother] saw the way the disease took her own mother, my grandmother, and when she got the diagnosis herself, she wanted to do the most she could to help science overcome it, so our family, and all other families might be able to avoid Alzheimer’s in the future. For my mother, that meant being a brain donor.

Brain donation is a tremendous gift to the future. It isn’t just about the donor, it’s about that person’s family, their community and the generations to come. Research using donated brain tissue has enabled scientists to answer important questions about many brain diseases, including Alzheimer's disease and related dementias. However, so much more remains to be understood. If you’re interested in helping to advance the understanding of how these disorders affect the brain and how we might treat and prevent them, consider signing up to donate your brain.

Organ donation is the act of taking healthy organs and tissues from one person and giving them to someone else. Making the decision to donate your organs is one of the most generous gifts you can give.

Find answers below to commonly asked questions about what it means to be a donor and how to become one. You’ll also find a list of federal resources to help you learn more about the donation process and how to get started.

Is there an age limit to becoming an organ donor?

No: There is no age limit for donation or to sign up. In 2021, one out of every three people who donated organs was over the age of 50. You’re never too old to make a difference — as of 2021, the oldest organ donor in the United States was 92.

How can someone register to be an organ donor?

You can register to be an organ donor at the time you renew your driver’s license or state ID at your local Department of Motor Vehicles. You can also register online.

Visit organdonor.gov to select your state and follow the steps to sign up.

Is my brain included when I sign up to donate my organs?

No. It’s common for people to think that signing up to be an organ donor includes brain donation, but the purpose and the process are different. This is because brain donation is only used to advance scientific research, versus helping another person stay alive through a transplant. Depending on the circumstances of death, it may be possible to donate organs for transplant as well as the brain for scientific research.

Brain donation is important in helping researchers to better understand how different disorders, like Alzheimer’s disease and related dementias, affect the brain, and how we might better treat and prevent them across different groups of people.

What happens after I sign up to be an organ donor?

After you sign up to be an organ donor, be sure to tell your family and friends. It’s important to let them know your wishes so they can honor your decision at the end of life. Also be sure to keep your information, such as a current mailing address, up to date in your state’s donor registry.

Who is responsible for determining if organs can be donated?

Organ Procurement Organizations (OPOs) are nonprofit organizations responsible for recovering organs from donors for transplantation in the United States. If you are near death or die, the hospital informs the local OPO. The OPO decides if you’re a possible donor based on your medical and social history.

Can I donate an organ or tissue while I’m still living?

Most donations occur after the donor has died, but it is possible to donate certain organs or tissue to someone in need while still living. Living donation has a different process than that of a deceased donor donation. To learn more about living donation, visit organdonor.gov.

Do any medical conditions exclude someone from becoming an organ donor?

Yes, some conditions such as an actively spreading cancer or infection, or heart disease, may prevent a person from becoming a donor. But you can still sign up as an organ donor regardless of any preexisting or past medical conditions. A doctor will conduct tests to determine the viability of your organs for transplant at the time of death.

Does it cost money to donate your organs?

No. The organ donor’s family is not charged for donation. Insurance or the people who receive the organ donation pay those costs. However, the donor’s family is still responsible for any costs associated with medical care at the end of life, and funeral and burial arrangements.

Can family members choose to donate their loved one’s organs after they die?

If a person is not registered to donate their organs, their family may make the decision on the dying person’s behalf to donate their organs. A member of the OPO must obtain consent from the family before organ donation. However, the family cannot override the person’s decision to donate their organs if they have registered to donate or stated it in their advance directives.

It can be challenging to think about organ donation at the end of life, both for the family and the person who is dying. Making and documenting this decision ahead of time as part of advance care planning and by registering to donate can help lessen stress during a difficult time.

Is organ donation possible if someone prefers to die at home?

In most cases, organ donation is not logistically possible when someone dies at home. Vital organs — such as the heart, lungs, kidneys, and liver — are only viable for a short time once oxygen stops flowing through the body. However, tissue and eye donation may be an option since these remain viable without oxygen for several hours.

Can a person have a viewing if they donate their organs?

Yes, it is possible to have an open casket funeral, or viewing, after organ donation. Hospital workers treat the body with care and respect during the donation process.
