Eating a poor diet
Oleksandra Naumenko/Shutterstock You already know a nutritional, well-balanced diet is essential to your heart and weight. But food’s benefits for the brain 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. Also, research shows that people who have a diet high in saturated fats are more likely to develop 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 opting for other lean protein sources including chicken and fish. Here are some of the treatable causes of dementia.
Ignoring chronic illness

To manage—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 at Providence Saint John’s Health Center in Santa Monica, California.
