6 Habits To Help You Outsmart Alzheimer's

In the US today, about a staggering 5.3 million people have Alzheimer’s disease, and that figure is expected to triple by the year 2050, according to the Alzheimer’s Association. Yikes!

Just to clarify, Alzheimer’s is a progressive, degenerative disorder in which plaque and tangles form in the brain, and brain cells become damaged, resulting in the problems with memory and thinking and changes in behavior and personality. While costly tools, brain scans and spinal fluid analysis, do exist today to allow medical professionals to see the identifying features of the disease in the brain, most cases are diagnosed based on presenting symptoms once the disease has already set in.

Alzheimer’s and dementia aren’t the same thing. Dementia is a group of symptoms affecting mental abilities which can be caused by a variety of conditions, including Alzheimer’s, Parkinson’s, Huntington’s, infections, HIV, depression, chronic drug use, and more.

Solutions do exist which can help ease the symptoms of the Alzheimer’s, but once the disease is symptomatic, it’s considered incurable and irreversible. In Outsmarting Alzheimer’s: What You Can Do To Reduce Your Risk, Kenneth S. Kosik MD writes:

Treating Alzheimer’s at this stage is a lot like treating cancer after it has already spread throughout the body or like treating heart disease after the first heart attack has already taken place.

Studies indicate that Alzheimer’s changes begin in the brain long before any symptoms appear, maybe even twenty years prior. Currently, there’s no drug or technological treatment for Alzheimer’s, but research is showing that lifestyle habits can dramatically reduce your risk of developing the disease and delay its onset.

A recent study, including more than a thousand people, aged 60 to 77, at risk for Alzheimer’s, determined that those people, who changed their lifestyles to include regular exercise, healthy eating, brain training, and management of metabolic and vascular risk factors, scored 25% higher than the control group on tests of memory, thinking, and problem solving.

In some particular areas, the results were profound. The scores of the better brain living group were a whopping 83% higher for executive functioning and processing speed was 150% higher! Researchers found that even people already experiencing early symptoms of dementia benefitted from the changes.

Habits Proven to Protect Your Brain

In Outsmarting Alzheimer’s: What You Can Do To Reduce Your Risk, Dr. Kosik outlines six key habits that have the most documented evidence for protecting your brain in what he calls a “Brain Smart Plan” :

Social Smarts – You can slash your risk of cognitive decline by staying actively connected to and supported by family and friends. Spending time with others helps to reduce stress levels and keeps many cognitive skills sharp. According to one study, “Lonely individuals may be twice as likely to develop the type of dementia linked to Alzheimer’s disease in late life as those who are not lonely.”

Meal Smarts – Diets rich in plant foods and low in highly processed foods preserve brain function and overall health. Brain smart eating also includes fish, a small amount of meat, olive oil, nuts, and some wine, coffee, and dark chocolate in moderation. Recent research showed that the MIND diet lowered the risk of Alzheimer’s by as much as 53 percent in participants who adhered to the diet rigorously, and by about 35 percent in those who followed it moderately well.

Aerobic Smarts – Kosik says, “The more you move, the fewer brain cells you lose.” Exercise even boosts the production of new brain cells. The amount of activity needed and level of intensity to benefit is surprisingly low. People who worked out at least three times a week for a minimum of 15 to 30 minutes were less likely to develop Alzheimer’s disease, even if it ran in their family according to one study. Exercise increases blood flow to the brain. Exercise triggers the release of brain derived neurotrophic factor (BDNF), which promotes neuronal growth and survival, reduces inflammation, and supports the formation of long-term memories. (For more info, see How Exercise Helps Your Brain)

Resilience Smarts – Long term, unrelenting stress, anxiety, depression, and other chronic emotional problems can raise your risk of Alzheimer’s by as much as 135% says Kosik. On the other hand, meditation, deep breathing, massage, and other relaxation practices can keep your brain calm, resilient, and healthy. Not all stress is bad, but chronic stress, can actually damage the brain. Various studies have shown that too much stress and elevated cortisol levels can can generate overproduction of myelin-producing cellsinhibits the birth of new neurons and causes the hippocampus, a brain structure integral to learning and memory, to shrink.

Train-Your-Brain Smarts – The more you challenge your brain, keep it stimulated, active and out of its comfort zone, the better equipped it will be to fend off Alzheimer’s. A Mayo Clinic study showed that a college education, mentally demanding job, and intellectually engaging hobbies postponed the development of Alzheimer’s in people who carried one of the “Alzheimer’s genes” by almost a decade. People without a high risk gene, were able to delay the disease even longer. It’s thought that ongoing education and mentally challenging work build “cognitive reserve,” the capacity for the brain to cope better and keep working properly even if brain cells are damaged or die.

Sleep Smarts – In Skimping On Sleep Can Make You Sick, Fat, And Stupid, I write:

Lack of sleep slows down your thinking, impairs your memory, concentration, judgment, and decision-making, impedes learning, and contributes to depression. Sleep is absolutely essential for your brain to work properly because during sleep your brain is busy processing information, consolidating memories, making connections, and clearing out toxins. When asleep, your brain does its housekeeping and not having adequate time to do this could potentially accelerate neurodegenerative diseases.

When you sleep too few hours or not deeply enough, you not only feel foggy and less alert the next day, but an ongoing sleep deficit prematurely ages your brain and raises the risk for developing Alzheimer’s disease.

    I feel less concerned after reading this article because I’m doing most of these action items and I like to hope being an information – junky – voraciously reading to learn daily will help keep my brain healthy!

  2. hey, I’m a 25 year old male living in Sweden. I visit this website at least once everyday and it has helped me tremendously. I think I can be a candidate for alzheimers later on in life and right now i’m taking the right supplements and working out to prevent that. thank you!

    • Robert,

      Thank you for your support. You are so smart for being aware and taking care of your brain from a young age. Keep it up, and you will surely benefit. (I think I will too even though I started later!) 🙂

  3. Hi Debbie, I’ve also read that vit D is a preventative supplement worth taking and apparently many folk are deficient in this vitamin. And I can attest to lack of sleep slowing down not only my thought processes but my entire body. Thanks for this.

    • Vitamin D is essential for the brain. Many are deficient now days because of the sunscreen we wear and not getting outdoors. Our modern lifestyles do not encourage brain health. The typical American lifestyle encourages mental decline. Sad.

    I almost refrained from commenting on yet another article on how you can avoid/outsmart/prevent etc. Alzheimers. They get old (pardon the pun). I do have to say the article is very well written. However, what I do want to say is that as I sat and watched my mom sit in a wheelchair in a vegetative state, with her eyes closed and blubbering gibberish at 70 years old, these articles mean nothing to the family members of the victims who DID everything these articles suggest they “do” to prevent/avoid/outsmart. My mom was as sharp as a tack and went back to adult school at the young age of 60 to learn another language. Mom was always learning new things, doing fun things, puzzles, card games, exercising, eating healthy, you name it, she did it, and then some. At the young age of 66 she was already in the nursing home with full blown Alzheimers. I’m not looking for sympathy, so please refrain. It is what it is. She’ll be 80 this year, yes she’s still hanging on. To what is anybody’s guess really. In my opinion, no matter what you do or try to do, we don’t get to decide who this disease strikes, independent of how many of these tips you follow.

    • Iva,

      I hear your frustration and am terribly sorry that your Mother has AD. In my article, I provide backup of scientific studies that give findings of percentages of reduced risk. The other side of those percentages are people who did develop the disease.

      There are always going to be people who do everything “right”, and still go on to Alzheimer’s, cancer, Parkinson’s, heart attack, and other. Unfortunately, there are no guarantees, and I certainly did not imply that here and hope other articles do not.

      All this is saying is that doing these things reduces the chances of developing AD. If a person chooses not to adhere to these, their risk increases, which on the flip side is no guarantee that they will get it either.

      Alzheimer’s runs in my family. My paternal Grandmother became symptomatic at an early age and lived with it for 14 years. Also, I am at a higher risk having had a brain injury. I choose to follow the practices above to lower my chances, but that doesn’t mean I won’t develop AD.

      I would hate to discourage people from living healthier lives because of examples like your mother.

      Blessings to you.
