How you can dodge dementia

All too often, folks think that a big reward demands a big effort. True, the astounding view from the top of Mount Everest is in direct proportion to the liferisking difficulty of the climb. But down here near sea level, the risk-reward ratio is often on your side — little or no risk, huge rewards. Wearing a bike helmet reduces your risk of a serious head injury by 70%. Walk your dog daily and, according to one international study, you’ll make 15% fewer annual doctor visits than someone without a dog. Another risk-free/big-reward deal: Five easy steps can slash your risk of dementia!

In 2015, Alzheimer’s Disease International reported that globally, nearly 47 million people are living with dementia; about 10 million new cases are diagnosed annually, and by 2050 there will be 11.74 million folks in North America with dementia — a 145% increase from 2015.

Why is the risk of dementia increasing? Because of increasing lifestyle challenges: obesity, heart disease, diabetes and sedentary habits, as well as smoking, excess alcohol intake and environmental toxins. Genetic predisposition also plays a part.

Fortunately, if you use your head, you can protect your brain! In a massive study published in JAMA, researchers looked at almost 200,000 people over age 60 (52% were women) for eight years and found that you can lower your risk for dementia by making four smart choices day to day. Even if you have a family history of Alzheimer’s, the researchers found that “a favorable lifestyle was associated with a lower dementia risk among participants with high genetic risk.” Those smart choices are:

1. No smoking.

2. Regular physical activity. 3. A healthy diet.

4. Moderate alcohol consumption.

We add a fifth to that list. 5. Social interaction and involvement with people and activities that inspire and comfort you.
