Alzheimer’s is the 6th leading cause of death in the United States. It actually kills more people than breast cancer and prostate cancer combined (1). Instead of putting the focus on preventing Alzheimer’s, the medical community puts emphasis on slowing the progression of the disease after onset with drugs and therapy.
However, if you truly understand dementia, then you can change your lifestyle to protect your brain from cognitive decline before it happens.
What is Dementia
According to the Alzheimer’s Association: “Dementia is a general term for a decline in mental ability severe enough to interfere with daily life… Dementia is not a specific disease. It’s an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person’s ability to perform everyday activities.” (2) Dementia is characterized by the impairment of at least two of these mental functions:
- Communication and language
- Ability to focus and pay attention
- Reasoning and judgment
- Visual perception
Dementia is a progressive illness, meaning that it gets worse as it progresses. It may start with forgetting where you placed your keys and can turn into forgetting your relatives or forgetting to eat.
The disease causes damage to brain cells and interferes with cell communication. This affects thinking, judgment, movement, behavior and feelings. Risk factors for dementia include (3):
- Head injuries
- Impaired thyroid function
- Low physical activity
- Poor diet and vitamin deficiencies
- Certain medication
- High cholesterol
- High blood pressure
- Alcohol use
- Old age
- Family history of Alzheimer’s disease
If you find yourself in these risk factor categories, taking steps in preventing Alzheimer’s now can improve cognitive function in older age.
Dementia vs. Alzheimer’s
Alzheimer’s is actually the most common type of dementia, accounting for 60-80% of cases. Other varieties of the disease include (4):
- Vascular dementia
- Dementia with Lewy bodies
- Mixed dementia
- Parkinson’s disease
- Frontotemporal dementia
- Creutzfeldt-Jakob disease
- Normal pressure hydrocephalus
- Huntington’s Disease
- Wernicke-Korsakoff Syndrome
Early signs of Alzheimer’s include having difficulty remembering recent conversations, names or locations, as well as apathy and depression. Later on, symptoms may include impaired communication, poor judgment, disorientation, confusion, behavior changes and difficulty speaking, swallowing and walking. Alzheimer’s is characterized by beta-amyloid deposits in the brain, twisted strands of the protein tau, as well as nerve cell damage and death.
9 Natural Tricks for Preventing Alzheimer’s Disease
If you are a high risk for dementia or if you have a family history of the disease, there are a few things you can do regularly to lower your risk of developing dementia. Preventing Alzheimer’s is straightforward, you just have to put in the work!
1. Quit Smoking
As Web MD puts it: “While smoking has long been known to increase the risk of dying from cancer and heart disease, researchers in Finland say they’ve found strong reason to believe that smoking more than two packs of cigarettes daily from age 50 to 60 increases risk of dementia later in life.” (5) It’s never too late to quit: “former smokers or people who smoked less than half a pack per day did not appear to be at increased risk of developing dementia.” Researchers theorized that the increased risk is partly due to the fact that smoking contributes to oxidative stress and inflammation. Many other studies have also confirmed the link between smoking and Alzheimer’s (6,7). If you’re having trouble quitting, there are many natural herbs that can support your efforts to ditch the bad habit and clear up some toxins in your lungs after quitting.
2. Be Physically Active
Physical activity has a positive impact on every part of your body, including your brain. In fact, it boosts oxygen and nutrient circulation to your brain and helps prevent risk factors like diabetes, high blood pressure, and more (8). In one study, researchers at the Cleveland Clinic in Ohio recruited almost 100 older men and women, aged 65 to 89, some of whom had a family history of Alzheimer’s disease. Half of these participants carried the carried the e4 gene, which substantially increased their risk of developing the disease (9). Participants were split into four groups:
- e4-positive group who exercised
- e4-positive group who did not exercise
- e4-negative group who exercised
- e4-negative group who did not exercise
The e4-positive group who did not exercise underwent significant atrophy of their hippocampus in as little as 18 months. In fact, the cerebral structure had shrunk by 3% on average. The e4 group that exercised experienced no change in their hippocampus and neither did the e4-negative groups. To benefit your brain, exercise moderately at least 3 times weekly and move around at least 30 minutes a day. Try walking around the block, swimming or cycling or get your blood flowing.
3. Vitamin B
B vitamins reduce the levels of a molecule known as homocysteine or HC in your blood. Hc damages the vascular system and can lead to strokes, heart diseases, and other vascular problems. These conditions, in turn, have a devastating effect on your brain. Also, raised homocysteine levels actually initiate cognitive impairment and poor brain performance, increase your risk of dementia, and boost brain shrinkage (10). In fact, adequate levels of B vitamins (folic acid, vitamins B6 and B12) slow down brain atrophy in patients with Mild Cognitive Impairment (MCI). Another B-vitamin, thiamine, helps brain cells produce energy from sugar to ensure proper brain function. Thiamine deficiency is linked to Korsakoff Syndrome, a chronic memory disorder part of the dementia umbrella (11). Reexamine your diet to include more vitamin B-rich foods. B12 is especially important for vegetarians, who may need to eat more eggs, dairy products, and dairy products.
4. Vitamin D
Vitamin D deficiency is one of the most widespread deficiencies in modern times, affecting 40-75% of all adults worldwide. The vitamin is produced by your body when your skin is exposed to direct sunlight. This vitamin is crucial for mental health and cognitive function. In fact, in a 6-year study examining 1,600 seniors, found that vitamin D deficiency was linked to Alzheimer’s Disease. “…those who were severely deficient in vitamin D were more than twice as likely to develop Alzheimer’s and dementia than those who had adequate levels,” writes Alzheimer’s.net on the study (12). To get your share, walk outside and expose your skin (no sunscreen) for at least 15 minutes a day.
5. Train Your Brain
Learning new information forces your brain to reorganize itself to make room for new knowledge. It also has to create new neuropathways to connect new and existing information (13). In fact, a Canadian study found that being bilingual supports cognitive function and even delays the onset of dementia in patients with probable Alzheimer’s Disease by 4 years on average. For other varieties of dementia, the onset was delayed by 3 years on average. For more benefits, practice brain-stimulating games like crossword puzzles and sudoku or play challenging games like scrabble and chess. Better yet, learn to play a new instrument or take a class at your local community college.
6. Prevent Head Injuries
Injuring your head causes short-term dementia-like symptoms like confusion, memory loss, and changes in speech, vision, and personality. Some head injuries can actually increase your risk of developing dementia later in life, especially if it causes 30 minutes to 24 hours of unconsciousness after initial injury (14). Researchers at Duke University Medical Center in Durham, North Carolina examined 548 veterans with a head injury and 1228 without head injury to yield these results (15). Protect your head by wearing a helmet while cycling, skating, skiing, or water sports to reduce your risk of dementia.
7. Control Your Alcohol Intake
Alcohol-related brain damage, caused by years of alcohol abuse can contribute towards Wernicke-Korsakoff syndrome and alcoholic dementia, the last of which are not truly classified as “dementia”. That’s because both conditions are reversible if you gradually reduce your alcohol intake. Your risk of Alzheimer’s disease and vascular dementia also go up with excessive drinking (16). According to the Alzheimer’s Society recommends drinking no more than 14 units of alcohol spread over 3 days a week. To put it in perspective, 125ml of wine is roughly 1.5 units while 1 pint of beer or cider is 2-2.5 units (17).
8. Track Your Numbers
Since diabetes, high cholesterol, and obesity are all risk factors, it’s important to monitor your weight, blood pressure, and cholesterol. If you don’t know where to begin, ask your doctor for tailored advice on your daily calorie, exercise, and diet goals.
9. Increase your Social interaction
Humans are social creatures, so spending too much time in isolation wears down your brain. In fact, being social is one of the easiest and most important steps towards preventing Alzheimer’s disease. “Feeling lonely rather than being alone is associated with an increased risk of clinical dementia in later life and can be considered a major risk factor that, independently of vascular disease, depression, and other confounding factors,” writes a 2014 study published in the Journal of Neurology, Neurosurgery, and Psychiatry. The study followed 2173 non-demented community-living older persons for three years. To prevent isolation, find a neighbor to accompany you on daily walks, sign up for a new cooking class to meet new friends or set up weekly phone calls with your loved ones. By practicing these brain-healthy habits, you can take active steps in preventing Alzheimer’s and keeping your mind sharp. Be sure to support brain health by supplementing your diet with anti-inflammatory food, fish oil, and coconut oil. Your brain is essentially the command center for your mind, personality, and your ability to understand and enjoy the world. Treat it right and you’ll have plenty of years of memories and experiences ahead of you. Source: https://dailyhealthpost.com/preventing-alzheimers/
