Reducing your risk of dementia starts with your everyday habits. Although some dementia risk factors can’t be changed, such as your age and family history, you do have the option to break these bad habits that increase your risk.

You already know a nutritional, well-balanced diet is essential to your heart and weight. But food’s benefits for the mind are sometimes overlooked. “The brain needs healthy fats, lean proteins, vitamins and minerals to function properly,” says Howard Fillit, MD, founding executive director and chief scientist of the Alzheimer’s Drug Discovery Foundation (ADDF) and the ADDF’s Cognitive Vitality Program. A review of research published in the journal Neurobiology of Aging found that a link between saturated fat intake and a higher risk of cognitive issues – including dementia. The best nutrition you can give your brain is a diet full of fruits, vegetables, nuts and grains. Replace butter with healthy fats, such as olive oil, and limit your intake of red meat, instead opt for other lean protein sources including chicken and fish.

Eating too much sugar

The list of reasons why you should lower your sugar intake continue to mount, with one of the newest ones being that a diet high in sugar may trigger dementia. Researchers from the University of Bath and King’s College London tested the brain samples of 30 individuals with and without Alzheimer’s disease for glycation, or the condition of having sugar molecules in one’s system. They found that those with Alzheimer’s disease were more likely to have issues with a vital enzyme called MIF as a result of glycation, according to their research published in 2017 in Scientific Reports. This meant they were able, for the first time, to link high blood sugar with Alzheimer’s disease.

Here are 10 things that happen to your body when you stop eating sugar.

Ignoring chronic illness

Untreated hypertension and diabetes are two of the greatest risk factors for dementia such as Alzheimer’s disease, explains Dr Fillit. “Diabetics have up to 73 percent increased risk of dementia and an even higher risk of developing vascular dementia than non-diabetics,” he says. “Having hypertension in middle age also increases the risk of both Alzheimer’s and vascular dementia.” For both diseases, managing them with medication, diet and exercise can lower dementia risk significantly. To contain – or ideally, avoid – chronic illness, be sure to keep up with your doctor’s appointments. “Patients who visit doctors are less likely to get dementia, as high blood pressure, diabetes and hypertension all can be modified when they’re under a physician’s surveillance,” says Clifford Segil, DO, neurologist.

These are the things you should – and shouldn’t do – before your next doctor’s appointment.

Drinking alcohol in excess

Hitting the bottle too hard can increase your risk for many health issues, including high blood pressure, stroke, liver disease, in addition to dementia. “Drinking too much can make people’s brains atrophy or get pickled, causing early onset memory loss,” says Dr Segil. “Multiple studies have shown a correlation between prolonged alcohol use and cognitive complaints.” In addition, years of drinking alcohol can cause rare forms of memory loss that lead to confusion, known as Wernicke-Korsakoff syndrome. It is safe for your health to drink in moderation – one drink a day for women and two for men. In fact, doing so (especially red wine) may be good for your brain health – and overall well-being – as the flavonoids in red wine are linked to a lowered risk of dementia in older people.

Smoking

Cigarettes and cigarette smoke contain more than 4,700 chemical compounds, including some that are highly toxic, says Dr Fillit. In addition, studies have shown that people who smoke are at higher risk of developing all types of dementia, and a much higher risk (up to 79 percent) for Alzheimer’s disease, specifically. The good news is that former smokers have a much lower dementia risk than current smokers, so the sooner you quit the better.

Living a sedentary lifestyle

Research has found a link between Alzheimer’s disease and inactivity, according to Aging and Disease. “Strong research shows that exercise benefits the brain and can reduce your risk of falls, age-related diseases and even death,” says Dr Fillit. When exercise is pumping oxygen and blood to your heart and muscles, your brain is benefitting too. The World Health Organization recommends that adults get at least 150 minutes of moderate-intensity (or 75 minutes of vigorous-intensity) aerobic exercise every week, which equates to working out 30 minutes a day around five times a week.

Lack of mental stimulation

Just as it’s important to exercise your body, it’s equally important to exercise your mind. Spending too much time glued to your couch, passively cycling through your Netflix queue instead of actively engaging your brain may increase your risk of dementia. “Research suggests that keeping the brain active seems to increase its vitality and may build its reserves of brain cells and connections,” says Heather Snyder, PhD, senior director of medical and scientific operations for the Alzheimer’s Association. Tapping these benefits is easy, too: “Complete a jigsaw or crossword puzzle, play games which require strategic thinking like chess or bridge or take a class online or at your local community college,” Snyder suggests.

Research published in The Journals of Gerontology in 2018 found an association between loneliness and social isolation and a higher risk of dementia. “This corresponds to earlier research that lonely people had double the risk of Alzheimer’s than their more social peers,” says Dr Fillit. Even if you’re more of an introvert and enjoy your alone time, try to put more effort into pursuing social activities, for example joining a book club, volunteering at an animal shelter, or participating in community sports.

Not getting enough sleep

Dr Fillit points to research linking sleep problems – such as insomnia and sleep apnoea – with an increased risk for Alzheimer’s disease. “In addition, a recent study estimates that 15 percent of Alzheimer’s disease cases may be attributable to sleep problems.” Other research published in 2016 in the journal Alzheimer’s & Dementia involving nearly 7,500 women found that averaging less than six hours a night of sleep raised risk of dementia by 36 percent. To lower your risk, Dr Fillit suggests establishing a bedtime routine, maintaining a regular sleep schedule, and treating sleep disorders, such as sleep apnoea. It’s also a good idea not to exercise or eat within two to three hours before bedtime, as both can impair sleep.
