What causes poor brain health?
There are many factors that can contribute to poor brain health, both controllable and uncontrollable. Poor brain health can stem from a combination of factors, both within and beyond our control.
Uncontrollable factors
There are two main uncontrollable factors that can influence brain health: genetics and age.
- Genetics: Some people are more predisposed to certain brain conditions, such as Alzheimer’s disease, due to their genes.
- Age: As we get older, our brains naturally decline in function.
Genetics Uncontrollable factors: Genetics is a major uncontrollable factor that can influence brain health. Certain genes can predispose a person to developing brain disorders such as Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease. These diseases cause the brain cells to deteriorate and die, leading to a decline in cognitive function, memory, and movement.
Scientists are still trying to understand exactly how genes influence brain health. However, research has shown that some genes can affect the production of proteins that are important for brain function. Mutations in these genes can lead to the development of brain disorders.
It is important to note that having a gene that increases your risk of a brain disorder does not mean that you will definitely develop the disorder. There are many other factors that can influence brain health, including lifestyle choices and environmental exposures.

Age Uncontrollable factors: Age is a significant uncontrollable factor that affects brain health. As we age, our brains naturally undergo changes that can lead to some decline in cognitive function.
Here’s a breakdown of how aging can affect the brain:
- Shrinking brain volume: Over time, the brain begins to shrink in size. This shrinkage is most noticeable in areas important for memory, learning, and executive function.
- Reduced blood flow: Blood flow to the brain also naturally decreases with age. This can impair the delivery of oxygen and nutrients to brain cells, which can further contribute to cognitive decline.
- Changes in neurotransmitters: Neurotransmitters are chemicals that allow brain cells to communicate with each other. Levels of certain neurotransmitters, such as acetylcholine, dopamine, and serotonin, decline with age. This decline can contribute to problems with memory, mood, and movement.
- Increased inflammation: Chronic inflammation throughout the body, including in the brain, is associated with cognitive decline. Inflammation can damage brain cells and impair their function.
It’s important to remember that the aging process affects everyone differently. Some people experience very little cognitive decline as they age, while others experience more significant decline. There are also things you can do to help protect your brain health as you age, such as maintaining a healthy lifestyle, staying mentally and socially active, and getting regular checkups with your doctor.

Controllable factors
There are many controllable factors that can influence brain health. By making positive choices about your lifestyle, you can help to protect your brain and keep it sharp as you age. Here are some key areas to focus on:
- Lifestyle choices: Diet, exercise, sleep, and stress levels can all significantly impact brain health.
- Poor diet: A diet that is high in unhealthy fats, processed foods, and sugar can contribute to cognitive decline.
- Lack of exercise: Regular physical activity is important for brain health. Exercise helps to increase blood flow to the brain, which can improve cognitive function.
- Sleep problems: Chronic sleep deprivation can impair cognitive function and memory.
- Stress: Chronic stress can damage brain cells and impair cognitive function.
- Head injuries: A concussion or other head injury can lead to cognitive problems.
- Substance abuse: Alcohol, tobacco, and illegal drugs can all damage the brain.
- Environmental toxins: Exposure to environmental toxins, such as lead and mercury, can impair brain function.
- Diet: A healthy diet that is rich in fruits, vegetables, whole grains, and lean protein is essential for brain health. These foods provide the brain with the nutrients it needs to function properly.
- Limit unhealthy fats, processed foods, and added sugar. These foods can contribute to cognitive decline.
- Exercise: Regular physical activity is important for brain health. Exercise assists with expanding blood stream to the mind, which can work on mental capability. It also helps to reduce inflammation throughout the body, which can protect brain cells from damage. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Sleep: Chronic sleep deprivation can impair cognitive function and memory. When you sleep, your brain consolidates memories and clears away waste products. Aim for 7-8 hours of sleep each night.
- Stress management: Chronic stress can damage brain cells and impair cognitive function. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
- Mental stimulation: Keep your mind active by learning new things, doing puzzles, and playing games. This can help to improve cognitive function and reduce your risk of cognitive decline.
- Social connection: Social connection is important for brain health. Strong social relationships can help to reduce stress, improve mood, and cognitive function. Make time for social activities and connect with loved ones regularly.
By making these lifestyle changes, you can take control of your brain health and help to keep your mind sharp for years to come.
If you are concerned about your brain health, it is important to talk to your doctor. There are many things you can do to improve your brain health, even if you have some risk factors.
