Improving Memory

In many ways, our memories shape who we are. They make up our internal biographies—the stories we tell ourselves about what we've done with our lives. They tell us who we're connected to, who we've touched during our lives, and who has touched us. In short, our memories are crucial to the essence of who we are as human beings.

That means age-related memory loss can represent a loss of self. It also affects the practical side of life, like getting around the neighborhood or remembering how to contact a loved one. It's not surprising, then, that concerns about declining thinking and memory skills rank among the top fears people have as they age.

What causes some people to lose their memory while others stay sharp as a tack? Genes play a role, but so do choices. Proven ways to protect memory include following a healthy diet, exercising regularly, not smoking, and keeping blood pressure, cholesterol, and blood sugar in check. Living a mentally active life is important, too. Just as muscles grow stronger with use, mental exercise helps keep mental skills and memory in tone.

Are certain kinds of "brain work" more effective than others? Any brain exercise is better than being a mental couch potato. But the activities with the most impact are those that require you to work beyond what is easy and comfortable. Playing endless rounds of solitaire and watching the latest documentary marathon on the History Channel may not be enough. Learning a new language, volunteering, and other activities that strain your brain are better bets.

Boost your memory by eating right

  Diet can help or harm brain health. Eating foods loaded with saturated fat boosts unhealthy low-density lipoprotein (LDL) cholesterol, which is bad for the heart and the brain. A Mediterranean-type diet, in contrast, can help preserve memory.   More »

Overeating may reduce brain function

High caloric intake could raise the risk of memory loss. A recent study suggests that high caloric intake over time may actually raise your odds of developing memory loss, or mild cognitive impairment (MCI), later in life. The study found that consuming between 2,100 and 6,000 calories per day may double the risk of MCI among people age 70 and older.  (Locked) More »

A possible brain food that you've probably never heard of

There's some research that lends some credence to claims that the nutrient Choline may be something of a "brain food" that fends off cognitive decline in old age. In the brain, choline speeds up the creation and release of acetylcholine, a protein that carries signals among brain cells and is important for memory and assorted other brain functions.  (Locked) More »

Putting more brain in the bank

Mental and physical activity seem to be equally important in keeping the brain active to ward off cognitive decline in older age. Exercise seems to affect the brain directly, increasing the number of synapses and enhancing the action of neurotransmitters, the chemicals that make brain cell–to–brain cell communication possible. It also increases the production of brain-derived neurotrophic factor (BDNF), a "brain juice" protein that promotes the production of new brain cells and the survival of existing ones.

Mild cognitive impairment: More than the usual forgetfulness

Some difficulty with remembering things (like names) and forgetting where you put things (like keys) is so typical that it's considered a normal part of aging. But some people experience a middle ground of cognitive impairment that's worse than normal age-related problems but not as bad as dementia from Alzheimer's disease or other brain diseases. Researchers labeled this intermediate state "mild cognitive impairment" in the 1980s, and the name stuck. Mild cognitive impairment stays mild in many cases. At the same time, studies have shown that people with the condition are about three times more likely to develop full-blown dementia than those without it. The problem is that doctors really don't yet have a reliable way of predicting who is going to "progress" to dementia and who isn't. (Locked) More »

More than the usual forgetfulness

Age-related memory loss is common, but forgetting things like significant dates or events could be a sign of mild cognitive impairment, which increases the likelihood of progression to dementia. The problem is that doctors really don't yet have a reliable way of predicting who is going to "progress" to dementia and who isn't. Moreover, memory impairment is a symptom of many conditions that affect older people that are unrelated to Alzheimer's disease. People with mild cognitive impairment are often aware of their memory problems, but self-reporting can be unreliable. Worriers may fret that they're impaired when they're experiencing completely normal forgetfulness, while others with true problems may try to bluff their way through them.  By briefly discussing current events or family matters with a patient, a doctor can sometimes get a sense of the person's memory and cognitive shortcomings. Information from family members and loved ones is extremely important. More »
