Thanks to amazing medical advances, more people than ever are surviving strokes – the blood clots and leaks that block blood flow to parts of the brain. A new study finds that a stroke ages your brain by eight years. Scientists from the  University of Michigan compared memory and thinking-speed tests before and after a stroke for 4 900 people, they found that having a brain attack eroded mental skills as much as if they’d aged almost a decade overnight.

But here’s the good news: while up to one in three Americans is at higher-than-average risk for a stroke, a whopping 80% of brain attacks don’t have to happen at all! Here’s a simple, seven-step plan to protect your noggin:

1. Take high blood pressure very seriously

Out-of-control blood pressure boosts your odds for a stroke four to six times. See your doc if you don’t know your blood pressure numbers or if you’re not sure whether they’re in the healthy zone – we think 115/75 is a good target for most people. Weight loss, exercise, a produce-packed diet that’s naturally low in sodium, and taking time to de-stress can help. And if you’re prescribed BP meds, take them! Then keep a spreadsheet of your numbers. Your brain is worth it. (2)

2. Do. Not. Smoke.

Cigarettes double your risk for an ischemic stroke, the most common type, caused by blood clots. Smoking raises your risk for a haemorrhagic stroke, caused by a leaky blood vessel, four-fold. It’s never too late to quit. Best plan: an anti-crave medication, nicotine-replacement patches and other products such as sprays and gums, plus a rock-solid support system. (3)

3. Lower your “lousy” LDL cholesterol:

High LDL levels can clog your carotid arteries, the big blood vessels at the sides of your neck that send blood to your brain, with fatty plaque. That boosts stroke risk.

Rebalance your LDL cholesterol level by eating fewer saturated fats (in fatty and processed meats, full-fat dairy products and processed foods), enjoying “good” fats (such as nuts, olive oil, fatty fish and avocados) in moderation, and walking 10 000 steps every day, no excuses. (4)

If your doc recommends a cholesterol-lowering statin, take it. Studies show that folks with a high stroke risk can lower their odds for a brain attack by 21% by taking a statin. Statins also help to prevent the brain aging that results from a stroke.

4. Control diabetes

Blood-sugar problems boost stroke risk by 50%. High blood pressure and high cholesterol often come with diabetes. Keep blood sugar in line, too.

5. Eat well

A Mediterranean diet – full of produce, good fats, fish, beans, plus some nuts, olive oil and red wine in moderation – could reduce your stroke risk by 18%, according to new research from Spain. Your brain will thank you for eating like you’re on a Mediterranean vacation, relaxing on the patio with grilled fish, a big salad and a glass of wine.

6. Get sweaty

Get 10 000 steps a day. Once you’re doing that, add tennis, gardening or swimming. Any activity that challenges you a little bit cuts odds for “mini-strokes” – transient ischemic attacks, which often presage a full-blown stroke – by 40%. These little strokes double your risk for brain dysfunction and boost your odds for a full-blown stroke five-fold. And they’re common: about 11% of people between the ages of 55 and 65, and 50% of people over the age of 80, have them. (5)

7. Act fast

If you or a loved one has any signs of a stroke, call for help right away. Signs include weakness or numbness on one side of the body; sudden confusion or trouble understanding; trouble talking; dizziness, loss of balance or trouble walking; difficulty seeing or double vision; and/or severe headache. Remember, time lost is brain lost.
