As early as your 20s two changes in your body can affect your memory: You begin losing brain cells and you're also producing less chemical fuel to power the brain cells that remain, according to the American Academy of Family Physicians. The more you age, the more impact these changes have on your memory. While short-term (things like the name of a person you just met) and remote memories aren't usually affected by aging, recent memory -- what you did last night or what you ate for breakfast this morning -- can take a hit. Check out the information below to discover the sneaky memory-stealing culprits that may be regular players in your daily routine.
Salty and Fatty Foods
You always knew a fatty and salty diet was bad for your heart, waist and more -- now research from the June 2008 issue of the "Journal of Alzheimer's Disease" reveals that it's probably bad for your brain, too. Over an eight-week period researchers at the Medical University of South Carolina fed a high-cholesterol diet to one group of middle-aged rats and high-saturated-fat diet to another. While weight gain and food intake were similar among both groups, the saturated-fat fed rats made more memory errors in a maze test, but researchers concluded that both diets can "profoundly impair memory." Your Cell Phone
A Swedish study of memory recall in rats found that radiation from cell phones affected the rodents' brain power. Researchers at the Division of Neurosurgery, Lund University in Sweden found that rats that were exposed to mobile phone radiation for two hours a week for more than a year had poorer results on a memory test than those that had no contact with mobile phone radiation. In earlier findings from the researchers, microwave radiation from cell phones affected the brain's ability to protect against nerve cell damage. The lead researcher Henrietta Nittby has a cell phone but uses hands-free equipment to avoid holding her phone up to her ear, according to ScienceDaily.com. Poor Sleep
People with sleep apnea -- a sleep condition where sufferers stop breathing temporarily many times throughout the night -- score worse than others on memory and cognitive tests, according to Harvard Health Publications. Using a continuous positive airway pressure (CPAP) machine -- a sleep-and-breathing aide -- helps improve scores on memory tests if sleep is improved. This is corroborated by a 2008 study that found that people with sleep apnea show tissue loss in brain regions that help store memory. Other studies have linked sleep deprivation to short-term memory loss and poor sleep to trouble remembering.
