1. Keep blood pressure healthy: This is the most important thing you can do. Decades before memory and thinking problems appear, high blood pressure creates microscopic scarring in the brain. It seems to damage tiny arteries that supply blood to the network of nerve fibres that brain cells use as a communication system. Take every step you can to keep blood pressure under 115/76.
2. Check your vision: You need sharp eyesight to keep Alzheimer's disease and other types of dementia at bay. But cataracts, glaucoma and other vision problems can get in the way. In one study, people with vision problems who saw an ophthalmologist were 64 per cent less likely to develop dementia than those who didn't.
3. Get help for depression: Depression doubles the risk for dementia. And in one study, a bout of major depression nearly tripled the risk among people with diabetes. The link might be high levels of the stress hormone cortisol, or the fact that it's just difficult to take care of your health when you're depressed. Ask your doctor for help getting a handle on depression.
