Top 10 Effective Ways to Prevent Alzheimer's in Seniors

1. Prevent Alzheimer's by Avoiding Smoking and Secondhand Smoke

The World Health Organization estimates that 14% of cases of dementia worldwide could be attributable to smoking. Dementia is a term used to describe a group of symptoms, most commonly memory loss, confusion, and communication problems. It occurs when brain cells stop functioning normally and is caused by diseases, most commonly Alzheimer's disease and vascular dementia. These diseases cause brain cells to die more quickly than changes in the brain related to normal aging.

There is evidence that exposure to nicotine, a component of cigarette smoke, can actually reduce the risk of dementia. Passive smoking has been shown to increase the risk of cancer, heart disease, and other diseases. Studies have also indicated that it can increase a person's risk of developing dementia later in life. Research suggests that the more exposure a person has to secondhand smoke, the higher their risk of dementia.

Smoking is a leading preventable cause of death, through heart disease, stroke, and lung cancer. It is a risk factor for lung disease, diabetes, rheumatoid arthritis, and poor immune function, as well as adversely affecting fertility and maternal health. Therefore, there are many general health reasons not to smoke.

2. Preventing Alzheimer's Disease through Regular Exercise

Exercise offers numerous known benefits for both physical and mental health, including reducing the risk of heart disease and diabetes, strengthening bones and muscles, and reducing stress. Studies show that physically active individuals are less likely to experience cognitive decline and reduce their risk of Alzheimer's disease. Physical activity is a modifiable risk factor known for dementia. Furthermore, regular exercise helps counteract other Alzheimer's disease risk factors, such as depression and obesity.

Exercising several times a week for 30 to 60 minutes can:

• Maintain sharp thinking, reasoning, and learning skills for healthy individuals
• Improve memory, reasoning, judgment, and thinking skills for individuals with mild Alzheimer's or mild cognitive impairment
• Delay the onset of Alzheimer's disease for those at risk or slow the progression of the disease
• Increase the size of the brain region involved in memory formation

Exercise can benefit your brain not only by keeping the blood flowing but also by enhancing neuroprotective chemicals. Exercise also tends to counteract some of the natural decline in brain connections that occur with aging. Overall, regular exercise is crucial for maintaining both physical and mental health.

Changes in the brain can occur many years before the first symptoms of Alzheimer's disease appear. These early brain changes suggest a feasible opportunity to prevent or delay cognitive decline symptoms. Eating a specific type of food or adhering to a specific diet may help prevent or slow down the memory loss caused by Alzheimer's disease. Many studies suggest that what we eat affects the thinking and memory abilities of an aging brain.

Eating a certain diet may influence biological mechanisms, such as oxidative stress and inflammation, which are the basis of Alzheimer's disease. Or perhaps the diet indirectly affects other risk factors for Alzheimer's disease, such as diabetes, obesity, and heart disease.

Among the dietary regimes, some healthy eating approaches show promise, such as the Mediterranean diet, which emphasizes fruits, vegetables, whole grains, legumes, fish, and other seafood; unsaturated fats like olive oil; and minimal red meat, eggs, and sweets. A variant of this diet, called the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet combines the DASH diet (Dietary Approaches to Stop Hypertension), which has been shown to lower high blood pressure, a risk factor for Alzheimer's disease.

Living with Alzheimer's disease or other memory loss conditions imposes demands on your life that can lead to stress. But too much stress can leave you feeling overwhelmed and affect both your health and your ability to function. Taking steps to reduce stress can help improve your focus, decision-making abilities, and overall quality of life. We all handle stress differently. But it can diminish your quality of life if not managed properly.

Effective stress reduction tips:

• Identify sources of stress in your life. Remove yourself from these situations whenever possible.
• Address the reasons why you are stressed and accept help in these situations. Work to change how you perceive the situation. Even the most challenging situations can have both positive and negative aspects. Challenge yourself to find the positive whenever possible.
• Learn what works best to relax you. Use these techniques regularly when feeling stressed or overwhelmed.
• Talk to a trusted family member or friend about your feelings.
• Change your environment. For example, if you are in an environment with too many stimuli causing stress, find a quiet place where you can relax and regroup.
• Take breaks when needed. Additionally, rest often to help preserve your energy.
• Utilize relaxation therapies. For example: Yoga or meditation; exercise/walking; write down your thoughts and emotions in a journal,...

If stress becomes overwhelming for you or you find yourself struggling with excessive stress and fatigue, seek medical help.

Sleep issues and Alzheimer's disease often go hand in hand. Understanding what contributes to sleep problems in people with Alzheimer's or other forms of memory loss. Many older adults have sleep problems, but those with memory loss often have more difficulty. Sleep disorders can affect up to 25% of those with mild to moderate memory loss and 50% of those with severe memory loss. Sleep disorders tend to worsen as memory loss progresses.

Sleep problems can include excessive daytime sleepiness and insomnia, difficulty falling asleep and staying asleep. Frequently waking up at night and early morning awakenings are also very common. Those with memory loss may also experience a phenomenon at night called sundowning. They may feel confused, agitated, anxious, and irritable. Wandering at night in this state of mind may not be safe.

To improve sleep quality, thus contributing to preventing Alzheimer's disease, you need to:

• Maintain regular eating, waking, and sleeping times
• Avoid stimulants
• Walk and engage in other physical activities
• Limit daytime napping
• Relax by reading or listening to gentle music
• Avoid using antidepressants, such as bupropion and venlafaxine, as they may lead to insomnia

6. Preventing Alzheimer's by Managing Blood Pressure in Middle Age

Most people with memory loss don't have just one single cause. Two or even three different issues in the brain lead to cognitive decline and functional impairment. For years, researchers have known that if you have high blood pressure, you're at increased risk of cognitive decline and dementia. High blood pressure, also called hypertension, is diagnosed when your blood pressure consistently stays at or above 140/90 mmHg. This is a serious condition that's a leading cause of heart attacks and strokes worldwide.

The SPRINT-MIND study found that people were less likely to have mild cognitive impairment if their systolic blood pressure was below 120 mmHg compared to the control condition of 120 to 140 mmHg. Therefore, for optimal brain health, it's best to keep systolic blood pressure below 120 mmHg, according to the SPRINT-MIND study. You can reduce your risk of cognitive decline and dementia by lowering systolic blood pressure below 120 mmHg, preferably through rhythmic exercise, a Mediterranean diet, and maintaining a healthy weight, along with medication if lifestyle changes alone aren't enough.

If you have high blood pressure, it's important to talk to your doctor before making any lifestyle changes or trying new medications so they can provide you with personalized recommendations and monitor your progress. High blood pressure initially doesn't have any symptoms, so it's important to be proactive and find out what your blood pressure is.

7. Preventing Alzheimer's by Learning Novel Stimulating Activities

One of the most dreaded prospects of aging is the potential for memory loss. Currently, there is no cure for Alzheimer's disease and other forms of dementia, but a study called the Brain Reserve Project provides hope that preventive measures may aid patients with Alzheimer's. Mental stimulation involves learning new skills or modifying our ways of thinking. Here's a list of tips to boost brain health through mental stimulation:

• Engage in various activities to challenge the mind
• Be creative and problem-solve
• Embrace novelty and change and avoid relying too much on habits
• Reduce negative thinking and closed-mindedness

To reduce the risk of developing memory loss, research tells us that we need to engage in diverse activities that provide mental stimulation. Engaging in a single activity will maintain a very limited set of neural connections. For example: completing crossword puzzles or word searches primarily reinforce neural connections related to words and language. Or participating in community education classes to learn a new skill like pottery or woodworking a few times a month and perhaps a foreign language class at a different time in the month. Novelty and change activate new neural pathways in the brain.

8. Preventing Alzheimer's by Treating Heart Disease

In fact, your cardiovascular health may be the most crucial factor in keeping your mind sharp over the long term. In a study from Finland, individuals with the best cardiovascular scores in midlife reduced their risk of developing memory loss later by up to 40% compared to those with the lowest scores. In another study, Swedish researchers found that individuals who develop cardiovascular risk factors more quickly are more likely to develop Alzheimer's disease and memory loss.

A study on good cardiovascular habits in young people showed that those who engage in many of these positive actions have fewer changes in the blood vessels in their brains, a measure of memory loss risk. According to another study, essentially, the earlier you have good physical fitness, the younger your brain age will be in the future.

Healthy arteries are typically flexible and allow blood to flow freely. If they stiffen, the heart will push harder to pump blood through, creating additional pressure, known as high blood pressure or hypertension. If a brain artery becomes completely blocked and blood cannot pass through, a stroke can occur, and brain cells may die. Depending on which part of the brain is deprived of nutrients, stroke victims may lose the ability to speak, have an unalert mind, lose normal emotional responses, or lose the ability to move normally. Many studies have shown that exercise makes arteries less stiff. Deep breathing and/or daily meditation help relax the brain and heart, aiding in overall body recovery.

Reading books prevents Alzheimer's disease and maintains overall brain health. Reading exposes the brain to the world of characters, landscapes, knowledge, ideas, art, and historical events. The science of reading's impact on the brain reveals promising results for maintaining mental sharpness in old age. There is increasing evidence that engaging in mentally stimulating activities will protect the brain from neurodegenerative diseases like Alzheimer's.

Researchers found that individuals engaging in the most mentally challenging activities, both early and late in life, have slower memory decline compared to those not engaging in such activities. Mental stimulation appears to help protect memory and cognitive skills, accounting for about 14% difference in decline beyond what was expected.

The nerve pathways related to memory retention, imagination, and information processing are also associated with reading and help prevent cognitive decline. All these components keep most reading abilities intact. However, if you experience difficulties while reading, it could be an early sign of Alzheimer's disease. Here are some ways to read for at least 30 minutes every day to prevent Alzheimer's and increase longevity.

• Read for 30 minutes every morning.
• Reading every night before bed is a great way to remember your 30 minutes of reading.
• Research topics of interest online.

Due to obesity rates, sedentary lifestyles, and an aging population, type 2 diabetes is more prevalent than ever in our society. For years, it has been known that type 2 diabetes increases the risk of stroke and heart disease. Recent studies have also shown that diabetes also increases the risk of memory loss. One hypothesis is that type 2 diabetes directly causes Alzheimer's disease.

Indeed, Alzheimer's disease is even referred to as 'type 3 diabetes' due to molecular and cellular similarities between diabetes and Alzheimer's. For example, insulin plays a crucial role in the formation of amyloid plaques, while insulin is also involved in phosphorylation processes, leading to nerve fiber disorders. In other words, insulin resistance in the body may be the cause of type 2 diabetes, while insulin resistance in the brain may lead to the plaques and tangles of Alzheimer's disease. Simply put, diabetes can lead to Alzheimer's disease.

The good news is that you can reduce your risk of type 2 diabetes and the risk of memory loss. You can consult a doctor to learn about diabetes and make lifestyle changes. Lifestyle changes such as engaging in physical activity, eating healthily, not smoking, etc., are helpful even if you are diagnosed with diabetes or pre-diabetes.
