These Hobbies Could Lower Your Alzheimer’s Risk, New Study Suggests

 Key Points

Engaging in diverse hobbies like socializing, exercising and reading may boost midlife brain health.

Managing conditions like depression, diabetes and high blood pressure supports long-term brain function.

Building cognitive reserve through stimulating activities may help reduce Alzheimer’s risk later in life.

 

Dementia affects millions of people worldwide, presenting profound challenges to individuals, families and health care systems. While we often associate cognitive decline with older age, the underlying changes in the brain actually begin during midlife. Subtle shifts can emerge decades before any clinical symptoms appear. Because these changes start early, we have a critical window of opportunity to take action and support our brain health long before memory issues become apparent.

The promising news is that while there are no magic bullets, there are steps we can take that may help protect our brain health as we age. By understanding and addressing factors like blood pressure, diabetes, hearing, mental health and lifestyle habits during midlife, we have the potential to influence our chances of staying cognitively healthy in the future.1

With this in mind, researchers set out to explore which mix of medical, genetic and lifestyle factors most strongly influence brain health in people ages 40 to 59. Drawing on data from a large group of adults, they examined not just individual risks and habits but also how these elements interact long before dementia symptoms typically appear. The results were published in Alzheimer’s and Dementia.2

How Was the Study Conducted?

To understand how lifestyle and medical history affect midlife brain health, researchers examined data from the PREVENT Dementia program. They focused on 587 adults between the ages of 40 and 59. At the start of the study, all participants were cognitively healthy, meaning they had no clinical signs of memory impairment or dementia. The research team recruited these individuals from five university sites across the United Kingdom and Ireland. Notably, they built the study group so that roughly half of the participants had a parent with a history of dementia.

The researchers wanted to see how various risk factors and protective habits interact decades before dementia symptoms typically appear. To do this, they evaluated participants across four main areas:

• Cognitive Testing: Participants completed a comprehensive battery of tests to measure their baseline brain function. These assessments looked at attention, language skills, visuospatial abilities and different types of memory.
• Modifiable Risk Factors: The study tracked 10 health and lifestyle factors that we can potentially change or manage with medical care. These included blood pressure, cholesterol levels, body mass index, blood sugar, hearing ability, sleep quality, signs of depression, smoking habits, alcohol intake and any history of traumatic brain injury. The team gathered this information using physical exams, blood tests, structured interviews and standard medical questionnaires.
• Nonmodifiable Risk Factors: Researchers also recorded baseline factors that participants cannot change. This included their age, biological sex and family history of dementia. Additionally, the team used blood samples to test for the APOE ε4 gene, which is a widely recognized genetic risk factor for late-life Alzheimer’s disease.
• Contributors to Cognitive Reserve: To measure protective factors, the team used a detailed questionnaire about life experiences. The questionnaire gathered information on formal education, career paths and how often participants took part in physically, socially or intellectually stimulating activities, such as playing an instrument, reading, exercising, socializing or traveling.

 

What Did the Study Find?

The researchers used advanced statistical models to look at all 17 factors together to see which habits and factors had the biggest impact on brain performance.

The standout finding was the power of stimulating activities. Engaging in physical, social and intellectual hobbies showed the strongest positive link to midlife cognitive performance. In fact, the positive association of these stimulating activities was larger than the negative impact of every single modifiable risk factor assessed and even outweighed the genetic risk associated with the APOE ε4 gene. Education also showed a significant positive relationship with cognitive scores.

When researchers broke down these stimulating activities, they found that the benefit did not come from just one magical hobby. Instead, participating in a variety of activities, such as socializing, playing music, making art, exercising, reading, speaking a second language and traveling, created a cumulative protective effect.

On the flip side, the study identified several factors linked to poorer cognitive performance. Among the modifiable risks, depressive symptoms had the strongest negative association with midlife brain function. This was closely followed by a history of traumatic brain injury, diabetes, high blood pressure, hearing impairment and poor sleep. For nonmodifiable factors, being male and being older were also associated with slightly lower cognitive scores.

The cognitive skills most affected by both the positive and negative factors were episodic and relational memory, which are the types of memory we use to recall specific events and the relationships between different pieces of information.

How Does This Apply to Real Life?

These findings highlight how day-to-day choices in midlife may influence brain health in the years ahead. While there is no guaranteed way to prevent dementia, certain activities and healthy habits are linked to better cognitive outcomes, even before signs of memory problems appear. It’s never too early to consider steps that might support long-term brain function.

First, focus on building your cognitive reserve through a rich, varied lifestyle. You do not need to master a single difficult task—instead, aim for a diverse mix of activities. Read books, join a walking group, learn a few phrases in a new language, take up a creative hobby or simply make it a point to socialize regularly with friends and family. This broad engagement acts as a workout for your brain networks.

Second, work with a health care provider to manage medical conditions that can quietly impact your brain. Take symptoms of depression seriously and seek treatment. Aim to keep your blood pressure and blood sugar in a healthy range. Consider getting your hearing tested if you notice changes, and prioritize getting a good night’s sleep.

Our Expert Take

This study published in Alzheimer’s and Dementia suggests that participating in a variety of hobbies—particularly socializing, playing music, making art, exercising, reading, speaking a second language and traveling—may lower the risk of Alzheimer’s disease. This research paints a clearer picture of how our daily lives shape our cognitive resilience.

Building cognitive reserve through stimulating activities can be a highly effective, accessible and enjoyable strategy for brain health. This study shows that dementia risk reduction is not just about avoiding negative factors like high blood pressure or head injuries. It is equally about actively introducing positive, enriching experiences into our routines.

Midlife is a crucial window. By managing medical risks and staying active socially, physically and intellectually, you could build a stronger, more resilient brain for the future.

Keep Forgetting Things? Neuroscience Says These 5 Simple Habits Boost Memory and Learning

Do things like these ever happen to you?

• You put your keys in a perfect spot. "They're right here on the table," you think. "Right here on the table." Later, you spend 25 minutes looking for your keys.
• You need three things at the store: bread, milk, butter. No need to write this down: "A loaf of bread, a container of milk, and a stick of butter. A loaf of bread, a container of milk, and a stick of butter." You get to the store, grab the milk, and you can't for the life of you remember the other two items.
• Your nephew asks something like: "Uncle Billy, remember when you came to Gram's house for Thanksgiving, and Uncle Jimmy reached in front of you, and Gram took out the little toy pig you had when you were kids for when people had bad manners, and she put it in front of Uncle Jimmy, but then Uncle Jimmy noticed something Uncle Chris did and moved the pig in front of him?" Meanwhile, you're thinking to yourself: "Wait, where did I go on Thanksgiving?"

It happens to all of us. (I'll confess all three examples above are mine from real life.)

At the same time, I've had the chance over the past few years to explore quite a few things that people can do to improve and sustain their memories, often based on research in neuroscience. Because, if there's one thing successful business leaders seem to share as they get older, it's that fear of losing their memory and other cognitive abilities is at the top of the list.

Before we forget some of the best of these, let's revisit them in one place.

1. Eat specific foods

This is a good one to start with, especially because I like the simplest bits of advice, and adding or emphasizing things in your diet is a pretty simple one. Specifics:

• Mushrooms. Writing in the Journal of Neurochemistry, Australian scientists reported last month that a specific type of mushrooms contain an active compound that "boosts nerve growth and enhances memory." Separately, Pennsylvania State University researchers found that other types of mushrooms -- porcini may be the best -- contain antioxidants that fight medical conditions associated with aging, like cancer, coronary heart disease, and Alzheimer's disease.
• Dark chocolate and cinnamon. Just to keep going, a few other tasty foods (albeit largely dissonant ones): dark chocolate (an Italian study suggests dark chocolate provides as much as three months' cognitive benefit) and cinnamon (a review in Nutritional Neuroscience of more than 2,600 studies found that cinnamon significantly improves cognitive function.)
• Vegetables of all kinds. A Harvard study followed the eating habits of 27,842 men over 20 years. Their conclusions? The ones who ate the most vegetables and fruit -- even fruit juice -- had less memory loss late in life.

Honestly, the mushrooms alone would be enough good news for this article for me, because there's practically no food I don't think it goes with.

2. Build good relationships

We've seen many times that the key to a happy and fulfilled life is very likely to focus first on your relationships. And there are so many simple, practical ways to improve relationship quality.

Perhaps most surprising: Make a habit of auditing your relationships. Write them down, and categorize the ones that provide value, and the ones you'd like to improve. It's a lot easier to improve things if you measure them.

Now, there's research suggesting memory is also impacted by relationships, and that (according to a Baylor College of Medicine study reported in the journal, Neuron), during periods of social isolation, the most prevalent cells in our brains, known as astrocytes, "become hyperactive, which in turn suppresses brain circuit function and memory formation."

3. Improve your environment

Another easy one: Michigan State University researchers studying Nile grass rats say they found that rats kept in dimly lit environments lost nearly a third of capacity in the part of their brains devoted to leaning and memory, compared with those in brighter environments.

As the study authors put it: "Dim lights are producing dimwits."

And, I think we can associate this one with the above: A study at the Chronobiology and Sleep Institute at the University of Pennsylvania found that even a small sleep deficit leads to correlative "deficits ... in vigilance and episodic memory."

Perhaps what's most fascinating about the last point is that at a certain level of sleep deficit, the brain loses the ability to sense just how tired you actually are.

4. Spend your time wisely

A variety of cognitive-based activities seems to help, among them:

• Detailed hobbies, like bird-watching, that require you to process and recall information.
• Reading for pleasure. Researchers from the Beckman Institute for Advanced Science and Technology at the University of Illinois Urbana-Champaign found that reading for pleasure, 90 minutes at a time, "strengthened older adults' memory skills."
• Doing brain games and crosswords. Researchers from Columbia and Duke universities found that study participants who did crosswords improved "cognition, function, and neuroprotection."

5. Walk backward

Let's end on this one. I love it because it's so unexpected and quirky. But, researchers at the University of Roehampton in London came up with the idea of testing whether simply walking backward could trigger better recall.

Sure enough, it worked. "Motion-induced past-directed mental time travel improved mnemonic performance for different types of information," said one of the study leads. "We have named this a 'mnemonic time-travel effect.'"

Ironically, I have to point out, "walking backward" is easier to remember than "motion-induced past-directed mental time travel."

Dementia: Two spices that can cut down the risk of Alzheimer's disease

How can you cut down the risk of Alzheimer's disease

Alzheimer's disease is a type of dementia characterized by loss of memory, language, problem-solving abilities and others. Although the condition is more prevalent among older adults, younger individuals are not untouched by it. It is true that as the risk of developing the condition increases with age, some diseases may even lead to dementia in the 30s and 40s. Besides, in most cases, the condition starts early, only the symptoms become predominant later in life. Till now researchers in the field of medical science have not been able to find a treatment to reverse the condition, but the risk factor can always be lowered by different means. From exercise to diet, several things can delay or cut down the risk of Alzheimer's disease. Now spices are the new addition to this long list.

How spices can help to cut down the risk of Alzheimer's disease

Healthy and clean eating is a topic that has always been stressed to live a long and healthy life. Even in the cases of mental health, a healthy diet plays a great role. Spices are one of the key ingredients of a cuisine. They not only enhance the flavours of the food but also support our health in several ways. Every spice present in your pantry is loaded with nutrients and can be beneficial for health in one or more ways. When it comes particularly to Alzheimer's, researchers believe that cumin and cinnamon can slow or cut down the risk.

What is special about cumin and cinnamon

Cumin and cinnamon are two different kinds of spices, widely used across the globe for preparing diverse foods. One is a seed, the other is a bark. They taste different and also have different nutrient content. But there is one compound that is common in both- polyphenols. Both spices are loaded with polyphenols-compounds that offer numerous benefits for memory and brain health.

​The role of polyphenols

Studies suggest that polyphenols have the ability to reduce brain plaque and inflammation. The compound can prevent cognitive impairment and Alzheimer’s. Studies also suggest that polyphenols can protect neurons against injury induced by neurotoxins, promoting memory, learning, and cognitive function.

Apart from that, the compound found in the two spices can help manage blood pressure levels, keep your blood vessels healthy and promote good circulation. They also help reduce chronic inflammation and manage blood sugar levels, reducing the risk of heart problems.

Other activities that can cut down the risk of dementia

The lifestyle choices you make in your 30s and 40s influences your health conditions later in life. So, you need to take measures earlier to reduce the risk of dementia and other chronic diseases that develop with time. Apart from adding these two spices in your food, some other things that you may do to cut down the risk of Alzheimer's includes:

Eating healthy

Exercising

Solving puzzles

Reading

Managing stress levels

Addressing underlying health conditions and

Staying happy
