But there are steps you can take to help keep forgetfulness at bay, according to the Johns Hopkins Health After 50 medical letter:

• Treat high blood pressure. Over time, hypertension can damage brain cells and trigger mini-strokes that may impair memory.
• Eat low-fat dairy products and nine daily servings of fruit and vegetables. This can improve alertness and energy.
• Exercise. Physical fitness and cognitive function are closely aligned.
• Drink moderate amounts of alcohol -- no more than about four ounces of wine, one ounce of spirits or 10 ounces of beer daily. This may lower your risk of significant memory loss.
• If you take prescription medications, check with your doctor about their possible impact on memory function.
• Get adequate sleep. Too little shuteye stresses the brain, which can affect your ability to concentrate, learn and recall information.
• Stay mentally active. Learn a new language, play chess, or practice the piano.
