5 more ways to lower Alzheimer's risk

1 Ditch saturated fats and replace with good monounsaturated fats and omega-3 essential fatty acids, which are found in such foods as avocado, nuts and wild salmon.

2 Pump up your brain with a new task, like learning to play an instrument or a foreign language, taking up ballroom dancing or sharpening your brain with crossword puzzles or Sudoku.

3 Dr. David Perlmutter, author of Grain Brain: The Surprising Truth about Wheat, Carbs, and Sugar - Your Brain's Silent Killers, believes that carbohydrates (even the so-called good ones) are largely responsible for the Alzheimer's, dementia, depression, epilepsy and ADHD epidemics.

4 Practice memorization by learning poetry.

5 Bust the stress - high cortisol levels cause brain cells to atrophy; be sure to preserve your brain cells by destressing daily.
