We\u2019ve covered a lot of scientific territory in this series, from the basics of Alzheimer\u2019s to the tests used to evaluate risk. This final installment is something you can follow up on right now, regardless of where you fall on the risk spectrum.<\/p>\n\n\n\n
Concerning your brain, let\u2019s say you\u2019re in one of these four situations:<\/p>\n\n\n\n
Everyone listed above will benefit from following these steps to support best brain function.<\/p>\n\n\n\n
Get regular physical exercise.<\/strong> Yes, I know, you hear this all the time, but the data showing that exercise prevents dementia grows ever more compelling. Just last week a Swedish study showed that women who were highly fit in middle age were 90% less likely to get dementia in their later decades than those who were deconditioned or even moderately fit<\/a>. 90%?! That should motivate you to walk outside several times daily, always take the stairs, and do some form of high-intensity workout. This one can be managed by people of virtually every age and ability in any location.<\/a><\/p>\n\n\n\n Tamp down the stress.<\/strong> Chronic stress from any source definitely increases your dementia risk. Make life choices based on how you answer \u201cWill the result of this choice increase or decrease my stress levels?\u201d Planning to get engaged to a heroin addict you\u2019re sure you can change? Pondering a well-paying job in the Trump administration? Get counseling if you need help making life-changing and potentially stress-inducing decisions.<\/p>\n\n\n\n Eat a ketogenic diet.<\/strong> If you\u2019ve read the words \u201cgoing keto,\u201d that\u2019s how you\u2019ll be eating. Your liver starts making specific chemicals called ketones from stored fats when it\u2019s running low on carbs. Blood levels of ketones increase, a condition called ketosis, and your brain function improves. Read more about the ketogenic diet here. <\/a>There are two steps to producing more ketones. First, switch to a low-carbohydrate, high-fat, moderate-protein diet. Second, incorporate intermittent fasting and go NPO (that\u2019s nothing by mouth except water) for 12 hours or more every day. Finish dinner by 7 pm and hold off eating breakfast until 7 am or even later.<\/p>\n\n\n\n In addition, because gluten triggers unnecessary inflammation, avoid it. Most of us can handle dairy, but purchase high-quality (organic or grass-fed) versions of milk, cream, and cheeses. Keep saturated fats low by using high-quality grass-fed beef and pastured chicken as a condiment rather than as a main course. Eating a keto diet, you\u2019ll learn to focus on lower-carb vegetables and lower-sugar fruits while you increase the amount of good fats you consume by eating more fish and avocados and using olive oil and other healthy fats<\/a>. This is low-inflammation eating. If all this seems daunting, our WholeHealth Chicago nutritionists can help you make sense of it.<\/p>\n\n\n\n Master the art of good sleep.<\/strong> It starts with a dark cool room, a quiet environment, limiting screen time, and being in bed before midnight. And since just about everyone over 45 wakes up sometime between 1 and 3 am, don\u2019t agonize over it. Go empty your bladder, get back into bed, and meditate. Morning will come.<\/p>\n\n\n\n Make a conscious effort to reduce your body\u2019s inflammation<\/strong>. Interestingly, some people can sense when they\u2019re inflamed because they have symptoms like fatigue, general achiness, skin eruptions, brain fog, and digestive problems. Your doctor can measure your inflammation with an hsCRP test. If yours is elevated, you and your doctor will need to play detective to find the sources. The big villains of inflammation are eating a nutritionally poor diet, leaky gut syndrome<\/a>, chronic infections (like Lyme disease, mold, chronic viruses such as herpes and Epstein-Barr, poor oral hygiene, and chronic sinusitis), and autoimmune diseases (like rheumatoid arthritis, lupus, and Hashimoto\u2019s).<\/p>\n\n\n\n Get your hearing checked<\/strong> and your teeth regularly cleaned.<\/strong> Untreated hearing loss equals diminished brain function, which in turn increases dementia risks. Floss daily.<\/p>\n\n\n\n Keep your hormones (thyroid, adrenal, sex hormones) at healthy levels<\/strong>. You may have to apply pressure to your doctor for cooperation on this, but \u201cborderline hypothyroid\u201d is not normal. For women, long-term sex hormone replacement (starting at the onset of menopause) definitely reduces dementia risks<\/a>. Ask your doctor for bioidentical hormones. You\u2019ll be taking a molecule that\u2019s completely identical to the one your ovaries were producing. Read more about bioidentical hormones replacement here.<\/a> Because there\u2019s an increased risk of breast cancer theoretically with any hormone replacement (1.2 times the average risk), annual mammograms are mandatory. Bioidenticals are not owned by Big Pharma, so all the studies testing the risks of hormone replacement have used the pharmaceutical Premarin. No one has performed a head-to-head study comparing the risks of Premarin with those of bioidenticals.<\/p>\n\n\n\n Keep your exposure to chemicals very low<\/strong>. If not you\u2019re not buying organic, which is ideal, wash fruit and veggies thoroughly. Most of what you\u2019ll eat on a keto diet are whole foods, but if you\u2019re buying a food with a label, read it closely. If you can\u2019t pronounce something or if it\u2019s another word for sugar, don\u2019t eat it. Challenge the necessity of any drugs you\u2019re prescribed. More than three quarters of Americans over age 50 are taking one or more prescription drugs, most of them prescribed to treat the consequences of unhealthful lifestyle choices.<\/p>\n\n\n\n Challenge your brain endlessly.<\/strong> Watch less TV and check your phone less often. Read more books, take some evening courses, join a choir, create art or write in a journal, and learn something new, like a foreign language or a musical instrument. Consider using one of the brain-fitness websites, such as brainhq.com.<\/p>\n\n\n\n Here\u2019s a list of the basic nutritional supplements that most researchers, including Dr. Bredesen of The End of Alzheimer\u2019s<\/em>, consider most helpful for maintaining optimal brain health (all are available in our Apothecary<\/a>):<\/p>\n\n\n\n This list will likely be longer if you\u2019re following the Bredesen Protocol (ReCODE) for restoring cognitive function and you\u2019ve had some abnormal test results.<\/p>\n\n\n\n
