Memory Loss Causes You Don't Know About

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 photo gallery 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 amongboth 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.

Your Diet

A new study from Tufts University's psychology department pitted the memory recall of low-calorie dieters against low-carb dieters, with some mixed results. Initial testing revealed that going completely carb-free may lead to lower performances on memory-based tasks. Memory improved after participants reintroduced carbohydrates -- though still sticking to a low-carb diet. Where low-carb dieters have the upper-hand is in reporting less confusion and a greater attention span compared with their low-cal dieter counterparts.

Being Underweight

. Obesity, associated with a slew of health problems including heart disease and diabetes, may not lead to memory problems in old age, according to a 2007 study published in "Neurology." Over the course of the six-year study, tests were administered to a group of about 4,000 people over age 65, of whom nearly 25 percent were obese. As time passed, neither obese nor overweight participants exhibited significant changes in memory or cognitive function. In fact, underweight participants demonstrated more brain drain over time -- which the authors note is consistent with

previous findings that weight loss or low (Body Mass Index) BMI in old age may be a precursor of cognitive decline or Alzheimer's disease.

Taking Too Much Medicine

You may want to rethink just how easily you pop that pill. For one, there's a slew of medicines known to cause confusion or decreased alertness, including steroids, heart medicines and antihistamines. Overuse of medicines may be the single biggest memory snatcher or cause of confusion in older adults, according to Jan Nissl, RN. This may be because how your body uses medicine changes as you age and because taking multiple drugs can enhance these effects.

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.

Menopause

Women often experience memory lapses and difficulty concentrating leading up to and during menopause. Estrogen therapy has been shown to help, but the Women's Health Initiative found that this seemed to increase the risk of dementia and cognitive problems, according to Harvard Health Publications. A recent study from the University of Illinois at Chicago found that the verbal memory problems women experience in midlife may go hand in hand with hot flashes. Other memory troubles -- shorter attention spans, working memory and visual memory -- were not associated with hot

flashes, but poor sleep, often a product of nighttime hot flashes, did impact these areas of memory.

Certain Surgeries

Weight loss surgeries, such as gastric bypass, can lead to a vitamin deficiency, which if left untreated, can cause memory loss and confusion, according to a 2007 study published in "Neurology." Deafness, vomiting and seizures were also reported symptoms. Another kind of bypass surgery, of the coronary artery variety, can also lead to confusion, fuzzy thinking, trouble concentrating, difficulty remembering and solving problems, according to Harvard Health Publications.

Experimenting With Drugs (Just One Time)

While you may know that alcohol and drug use can lead to impaired judgment, coordination and memory, some scientists assert that trying ecstasy just once could damage your memory. Researchers from the University of Hertfordshire's School of Psychology have found that compared with non-users those who've tried ecstasy show significantly impaired memory and that the amount of ecstasy consumed is largely irrelevant, according to reporting from ScienceDaily.com.
