The leading cause of dementia worldwide is Alzheimer’s disease. More than 55 million people suffer from this condition. Gradually, it destroys memories and cognition, drastically changing the lives of those affected and their loved ones as well.
Even though genetics and age are two primary risk factors of Alzheimer’s disease, there’s some good news. Research shows that daily lifestyle decisions have an immense impact on brain health and the risk of developing Alzheimer’s disease.
Thus, since you have the ability to change and control many lifestyle factors, you can manage your cognitive future. Unlike genes, you have the power to influence many things in your life, which is a relief and a source of hope.
Starting with eating habits, sleep patterns, exercising, and socializing, understanding what lifestyle choices cause Alzheimer’s will determine your brain health in the future. So, taking control over your everyday lifestyle decisions is a step in the right direction for preventing Alzheimer’s disease.
What Lifestyle Habits Cause Alzheimer’s?
Now that you have a basic understanding, here are the common and lesser-known lifestyle factors that increase the risk of Alzheimer’s disease.
1. Sedentary Lifestyle
Not exercising is a serious risk factor for Alzheimer’s disease. It impairs blood and oxygen supply to the neural tissue. The levels of BDNF, a protein crucial for neuron growth and survival, increases due to exercise. But when we’re not exercising, it causes BDNF levels to decrease.
It makes it difficult for the brain to make new connections and even keep the old ones. Less neuroplasticity makes your brain susceptible to age-related changes and the neurodegenerative processes that lead to Alzheimer’s disease.
2. Poor Diet
A diet rich in sugars, processed foods, and trans fats is toxic to brain cells. These foods lead to inflammation and oxidative stress in the body. This type of inflammation can damage neurons and accelerate cognitive decline. Ultra-processed foods are low in nutrients but increase insulin resistance.
Insulin resistance which impairs glucose metabolism in the brain. If not enough glucose is processed, it allows beta-amyloid and tau proteins to build up in the brain. Beta-amyloid and tau are characteristic of Alzheimer’s disease. A head specialist doctor in Patna would emphasize that you eliminate ultra processed foods from your diet.
3. Inadequate Sleep
Sleep cleanses the brain of metabolic waste and toxic proteins during sleep. The glymphatic system is highly active during the deep sleep stages. It removes beta-amyloid plaques that accumulate during your waking hours.
Not getting enough sleep or poor quality of sleep prevents the removal of these toxins. This can increase the buildup of harmful substances in the brain. Not to mention, if you’re not sleeping well, it also impairs memory consolidation and elevates stress hormones that can hurt brain function.
4. Smoking
Cigarettes damage the blood vessels of the brain, decreasing oxygen and nutrient supply to the brain. Smoking narrows the arteries that supply the brain with oxygen. It increases the risk of stroke.
Smoking also produces free radicals that harm the brain, causing oxidative damage to neurons. It accelerates cognitive decline, and smokers have a higher risk of dementia compared to non-smokers.Thus, smokers should quit smoking to maintain their brain health.
5. Excessive Alcohol Consumption
Alcohol impairs the structure and function of the brain. It affects the parts of the brain that handle memory and learning. Excessive alcohol consumption depletes thiamine (vitamin B1). Thiamine depletion causes Wernicke-Korsakoff syndrome and permanent brain damage.
Drinking alcohol can disrupt sleep, impair glucose metabolism, and cause inflammation in the nervous system. Some moderate drinking is protective, but too much is damaging. It disrupts the brain’s natural processes of repairing damage and accelerates the neurodegenerative changes that lead to Alzheimer’s disease.
6. Chronic Stress
If you’re exposed to stress hormones for a long time, it creates a toxic environment for brain cells. The stress hormone cortisol is especially damaging to the memory-making part of the brain, the hippocampus. Stress elevates cortisol levels, which shrinks the hippocampus. It causes inflammation and oxidative damage.
Stress can also disrupt sleep, weaken the immune system, and lead to unhealthy eating patterns. This creates adverse effects on cognitive health. Thus, it’s crucial to learn stress management skills to protect brain health and prevent Alzheimer’s disease in future.
7. Social Isolation
Social isolation and loneliness increase the risk of dementia. This happens because you don’t have enough social stimulation. Being around others helps you to stimulate your brain.
Conversation, emotion processing, and social reasoning are examples of mental stimulation. On the other hand, loneliness and social isolation can lead to depression and anxiety. And as a matter of fact, depression and anxiety accelerate cognitive decline.
Thus, it’s important that you spend time socializing to stimulate your brain, receive emotional support, and be more motivated to make healthier choices. You should ideally maintain social relationships throughout your life. It’s a strong protective factor against the development of Alzheimer’s disease.
8. Low Mental Stimulation
This follows the previous point. A healthy brain keeps its cognitive reserve. It’s the brain’s ability to cope with the changes that come with aging. However, cognitive reserve weakens when the brain isn’t used for continuous challenges and learning.
In general, reading, puzzles, learning new skills, and problem-solving require you to engage your brain. So, engaging in these activities regularly helps build cognitive reserves. It’s a defense against the symptoms of Alzheimer’s disease. It might even delay its onset, even if pathological changes have already started.
9. Excessive Screen Time & Passive Media Consumption
Too much time spent watching a screen will decrease brain stimulation and cognitive engagement. Passively watching movies and scrolling doesn’t stimulate the brain.
When you do these activities, you don’t actively stimulate your brain because it requires minimal neural processing.
In fact, too much screen time often takes the place of physical activity, socializing, and mentally stimulating activities. To make matters worse, blue light from the screen interferes with your sleep cycle as well.
So, it damages your brain in other ways, too. This is why you need to balance screen time with active activities to maintain your brain health.
10. Overuse of Anticholinergic Medications
Acetylcholine is a neurotransmitter that helps you to remember and learn. Many drugs that people take interfere with this neurotransmitter. These drugs are anticholinergic. An anticholinergic drug interferes with acetylcholine in the brain.
Some common examples are some antihistamines, sleep aids, bladder medications, and antidepressants. Long-term anticholinergic drug use increases the risk of dementia and also speeds up cognitive decline.
If you have to take these medications, talk to your doctor or consult an advance neuro hospital in Patna. Try to limit their use and use alternative therapies when possible and prescribed by your doctor.
11. Exposure to Air Pollution
Exposure to certain air pollutants can contribute to neuroinflammation in the brain. Pollutants like fine particulate matter and nitrogen dioxide can cross the blood-brain barrier and initiate a cascade of harmful effects. Areas near high traffic and industrial zones pose the greatest risk.
You can lower your exposure to air pollution by using an air filter in your home, driving at non-peak times, and supporting clean air legislation.
12. Vitamin D Deficiency
Deficiency of vitamin D can compromise the immune system and lead to neuroinflammation, which are the two factors associated with your cognitive decline.
Vitamin D helps regulate the amount of calcium in neurons and plays a role in the synthesis of neurotransmitters. Deficiency is common, especially among older adults who don’t get enough sunlight.
You can keep your vitamin D levels in the recommended range with blood testing and prescribed supplementation. Vitamin D-rich foods also help.
13. Poor Oral Health
Poor oral health is one of the lesser-known risk factors responsible for Alzheimer’s disease. It can contribute to the chronic inflammatory state that leads to increased risk for Alzheimer’s.
Bacteria from gum disease can enter the bloodstream and may find their way to the brain. Poor oral health is often a result of poor nutrition and may correlate with diabetes. So, it’s crucial that you protect your mouth with regular visits to the dentist and good oral hygiene.
14. Hearing Loss (Untreated)
Hearing loss is a major factor in cognitive decline. Research shows that untreated hearing loss can cause cognitive impairment and damage your ability to remember and think because the brain has to work harder on what it can’t hear.
Isolation can also accompany hearing loss, contributing to a reduction in cognitive function. So, to maintain healthy cognitive function, use hearing aids and listening devices.
FAQs
We’ll wrap up the blog with some common questions we get about preventing Alzheimer’s and cognitive decline:
1. Can stress alone cause Alzheimer’s?
No, but stress is known to contribute to cognitive decline. Stress degrades the brain’s memory centers and leads to chronic inflammation.
2. Can I reduce my risk even if I have a family history?
Yes, lifestyle changes can reduce risk even in the presence of genetic factors. The progression and symptoms of Alzheimer’s disease is not entirely caused by genetics.
3. Is Alzheimer’s preventable with lifestyle changes?
Many scientists think that Alzheimer’s disease is preventable with lifestyle changes, but no one can guarantee that. Alzheimer’s involves complex genetic and environmental factors.
4. Does mental activity really make a difference?
Yes, the most well-known result of mental stimulation is the creation of cognitive reserves. This cognitive reserve can reduce the impact of Alzheimer’s, even when brain changes have occurred.
5. Are supplements effective in preventing Alzheimer’s?
Most of the supplements out there don’t show much promise for preventing Alzheimer’s. A well-balanced diet provides most of the nutrients we need, anyway.
6. Does poor sleep increase Alzheimer’s risk?
Yes, poor sleep increases the risk for Alzheimer’s disease by interfering with the natural process that cleans the brain of toxic proteins.
7. Is hearing loss really that serious for the brain?
Yes, untreated hearing loss contributes to dementia by forcing the brain to compensate for the loss of sound.
8. What’s worse for the brain — sugar or fat?
Sugary foods like processed sweets can cause immediate harm. Sugary foods can lead to chronic inflammation and insulin resistance. However, trans fats can also damage the brain and have harmful effects on brain structure.
Early Action Makes a Difference!
The takeaway from this blog is that Alzheimer’s involves many modifiable factors. There are many different causes of Alzheimer’s, and knowing what those reasons are lets us take control of our brain health. Not every factor we change will lead to lower risk, but having multiple protective factors helps us create a better environment for the brain.
It is likely that the different types of Alzheimer’s progress differently, but we know that lifestyle factors influence all of them. The most effective time to act is early on, but it’s never too late to make beneficial changes. After all, prevention is always the best way to ensure brain health.
