Could Retirement Harm Your Brain?
You’ve worked decades toward retirement, and it is finally here.
You look forward to the unhurried schedule, traveling, and more time with family.
But could retirement also be a risk factor for dementia?
As rates of Alzheimer’s disease and other dementias have increased over the past several decades, researchers have looked closely at the factors that may accelerate cognitive decline. Interestingly, retirement repeatedly shows up as an important transition point:
* A 2016 French population study found that later retirement was associated with a lower risk of developing dementia. (https://pubmed.ncbi.nlm.nih.gov/27102789/)
* A 2017 study found that verbal memory declined 38% faster after retirement compared with before retirement. (https://pubmed.ncbi.nlm.nih.gov/29280030/)
* A 2017 U.S. study found that longer time spent in retirement was associated with faster episodic memory decline. (https://www.sciencedirect.com/science/article/pii/S0277953617300266)
* A 2026 study found that continuing to work was associated with slower executive-function decline, while retiring at age 65 or later was associated with slower memory decline compared with retiring earlier. (https://alz-journals.onlinelibrary.wiley.com/doi/10.1002/alz.71372)
* A 2026 study found that early retirement was associated with lower memory and executive-function scores and a greater likelihood of cognitive impairment in women. (https://pubmed.ncbi.nlm.nih.gov/42773884/)
As they say, “Where there’s smoke, there’s fire.” Having seen this phenomenon play out in my patients, as well, I wanted to spend some time going through why I believe this is happening and an encouragement for anyone working, thinking about retiring, or having recently retired.
Why Retirement May Increase Dementia Risk
The initial lesson here is not that retirement itself causes dementia. Rather, retirement can abruptly remove many of the things that keep the brain healthy: challenge, learning, social interaction, structure, and purpose.
Retirement is a major shift in how you live your day-to-day life, and this major shift can be extremely difficult for us. We, Americans in particular, are motivated by and even conditioned to work — childhood chores and allowances, repeatedly being asked “What do you want to be when you grow up?”, getting a high-school job, career-oriented education, and the intertwining of work with the American Dream. None of these are particularly good or bad but rather just the reality of living in America — we love to work and make what we do professionally as part of our personal identity.
When it comes to the brain, work can very much be dementia-preventing:
* Regular problem-solving
* Ongoing learning opportunities
* Social interaction with employees and clients
* Our daily routines are more structured
* Provides a sense of purpose and meaning
But once we stop working, many of us run the risk of losing that sense of purpose and meaning to our lives. With so much time and energy dedicated to work, it often becomes part of our identity. Work was the reason we got up in the morning, it provided money and security, it made us feel like we were doing something good. In retirement, all of that goes away. You can now see this gap and must face this new void in your life.
And so many retirees gradually fall into a monotonous life without realizing it. They can lose their motivation and drive for life, rarely leaving the house. Without friendships outside of work, they rarely engage in meaningful conversation anymore. Their days become unstructured, sleeping and eating at odd hours. They no longer seek out challenge.
How retirement may become dementia-promoting:
* Lack of opportunity to problem-solve and learn new things
* Social circles can become incredibly small to non-existent
* Sleep and nutrition are less structured
* Less daily movement
* A loss of purpose and meaning
Retire-Proof Your Brain
For those who have not yet retired (or recently retired), you have an enormous opportunity to protect (retire-proof?) your brain. In his book The Way of Excellence, Brad Stulberg, a fellow Ashevillian, uses a great metaphor about identity and building a multi-dimensional life that I think applies particularly well here:
Imagine your life is a house that you are constantly remodeling. Each room of this house represents an aspect of your identity (a career room, a family room, a health room, a hobby room, etc). If you built your house to have such a large career room that it crowds out space for any other room, then once that career is over and the door to that room gets locked, you will have no where else to go. The other rooms are so small and have been neglected for too long to enter and enjoy.
This is the problem. So, I encourage you to protect and expand the other rooms in your house.
* Keep the family room metaphorically bright and playful.
* Have a hobby room that you retreat to a few times per week.
* Keep the health room clean.
* Invite your friends over.
Seasons of life will naturally demand that one room expand more or contract. But once a year, reflect on your identity house: Are you comfortable with the size of each room? Is one room crowding out all the others? What needs your attention before the next season arrives?
Retirement can be a wonderful opportunity to enjoy the life well-worked. Though you are stopping work, my parting advice is not to stop caring for yourself at the same time. Keep your brain and body working for you, for your family, and for your community.
