As people age, bodily systems, including the brain, gradually decline in function. At this point, brain aging not only affects health but also impacts memory and mental state in older adults. So, what is brain aging, and are there ways to slow down the process of brain aging?
1. What is Brain Aging?
Brain aging is the process of decreasing brain volume and function with age. It is a complex process affecting everything from the cellular level to the organ level, starting from a young age and accelerating with age.
Morphologically, brain aging is primarily characterized by brain volume loss, cortical thinning, white matter degeneration, loss of gyrification, and enlarged ventricles. Physiopathologically, brain aging is associated with neuronal atrophy, dendritic degeneration, loss of myelin, small vessel disease, slowed metabolism, activation of microglia, and white matter lesions.
Brain weight and volume decrease with age, but changes in the brain do not occur at the same level across all brain regions. The prefrontal cortex, striatum, temporal lobe, cerebellar vermis, cerebellar hemispheres, and hippocampus are the areas that experience the most significant volume reduction during brain aging.

The most widely observed cognitive change related to brain aging is memory. Memory declines during brain aging. Older adults may experience memory issues such as difficulty remembering names or words, decreased attention span, or reduced ability to multitask.
As the brain ages, neurons begin to die, and cells produce a compound called amyloid-beta, which is a risk factor associated with Alzheimer’s disease. It can also be found in the brains of some aging individuals. The presence of amyloid-beta plaques in the brain may be a sign of Alzheimer’s disease, a common form of dementia.
Overall, as the brain ages, older adults will encounter more difficulties in self-care.
2. Ways to Slow Down the Aging Process of the Brain
Brain aging can cause significant difficulties for older adults, leading to feelings of frustration, sadness, and disappointment. Therefore, proactively preventing brain aging early on is essential. Here are some ways to slow down the aging process of the brain that you might consider:
2.1. Exercise Regularly
Physically active individuals are more likely to keep their minds sharp. Regular physical activity can also improve balance, flexibility, strength, energy, and mood. Research shows that exercise can reduce the risk of Alzheimer’s disease.
For most healthy adults, it is recommended to engage in at least 150 minutes of moderate aerobic activity, such as brisk walking, each week. Alternatively, aim for at least 75 minutes of vigorous aerobic activity, such as running, per week. It’s best to spread this activity throughout the week. If you can’t find time for full workouts, try walking for 10 minutes a day.
2.2. Protect Your Head
Head injuries can have significant long-term impacts on a person’s life. They can affect thinking, memory, coordination, speech, and emotions. To protect your brain, always wear a helmet when engaging in activities with a risk of head injury, such as biking, skiing, horseback riding, or using a motorcycle, snowmobile, or all-terrain vehicle.
Common causes of head injuries include car accidents and falls. To prevent head injuries, wear a seatbelt while driving. To avoid falls, be cautious when using ladders, walking on uneven surfaces, or in unfamiliar areas. At home, prevent falls by clearing clutter from stairs and hallways, ensuring stairs are well-lit, and securing all rugs and mats to the floor to prevent slipping.
2.3. Manage Your Health
Certain medical conditions can increase the risk of cognitive and memory problems, as well as brain aging. These conditions also increase the risk of stroke, which can damage blood vessels in the brain. Common conditions include diabetes, heart disease, and high blood pressure.
If you have ongoing medical issues, follow your doctor’s guidance on the best ways to treat and manage them. If you do not have these conditions, take steps to prevent them.
2.4. Socialize with Friends
Increase social interactions and meet with friends regularly. Socializing helps prevent depression and stress, both of which can accelerate brain aging. Social isolation and loneliness are also linked to a higher risk of cognitive decline and Alzheimer’s disease.
2.5. Get Enough Sleep
Sleep plays a crucial role in brain health. A good night’s sleep improves brain function and memory, helps you stay alert, and makes daily tasks easier. Rest also reduces stress and depression.
Aim to improve sleep quality and maintain 7 to 9 hours of sleep per night. Conditions such as sleep apnea can disrupt sleep and increase the risk of cognitive decline and dementia. If you have trouble sleeping, consult a doctor for timely intervention.

2.6. Eat a Healthy Diet
Research has found that a healthy diet can play a role in preventing or delaying symptoms of dementia. In particular, the MIND diet can be a valuable tool for brain health.
MIND stands for Mediterranean-DASH Intervention for Neurodegenerative Delay. This brain-healthy diet provides fuel to the brain, helping to improve mental focus and slow the decline in cognitive skills. The MIND diet emphasizes plant-based foods, including a variety of leafy green vegetables, other vegetables, berries, nuts, whole grains, poultry, and fish. At the same time, it limits foods like butter, cheese, red meat, and sweets.
2.7. Challenge Your Brain
Just as physical activity helps keep the body healthy, engaging brain activities can help keep your brain healthy. These activities can improve brain function and memory, such as solving crosswords, reading, playing games, learning to play a musical instrument, or trying a new hobby.
2.8. Avoid Stimulants and Alcohol
Tobacco and stimulants can reduce the volume of gray and white matter in the brain, accelerating brain aging. Therefore, to slow down brain aging, it is important to quit smoking and avoid stimulants.
Consume alcohol in moderation to ensure good health and brain function. The recommendation is up to one drink per day for women and up to two drinks per day for men. Excessive alcohol consumption increases the risk of falls and can cause memory problems. It may also exacerbate certain medical conditions affecting the brain, such as high blood pressure and diabetes.
3. Key Points to Note in Slowing Down Brain Aging
Brain aging is a natural process of life, and you cannot prevent it from occurring. However, we can certainly slow down the process of brain aging. To effectively slow down brain aging, you should consider the following points:
- Changing your lifestyle, diet, and exercise routine is essential for improving brain health.
- Avoid risk factors that accelerate brain aging, such as smoking, alcohol, and prevent head injuries.
- Getting enough sleep and reducing stress also contribute to slowing down brain aging.
- Monitoring and managing chronic health conditions like high blood pressure, diabetes, and high cholesterol can help reduce the risk of affecting brain health.
- Additionally, supplementing micronutrients through supplementation is one of the fastest and most effective ways to improve brain health and prevent brain aging.
Thus, brain aging affects health, mental well-being, and the ability to perform daily activities in older adults. Therefore, to live longer, healthier, and with better quality, you should proactively adopt ways to improve physical and brain health right now.
