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.

Hearing aids may help improve brain function

More than nine million adults ages 65 and older have some level of hearing loss, but only 20% who need hearing aids wear them. A new study found that hearing aids can not only improve the ability to hear, but also restore lost brain function in terms of working memory, selective attention, and processing speed.  More »

The genetic link between Alzheimer's and heart disease

When told they have a genetic risk for Alzheimer’s disease, people may experience less distress if they learn that the same gene variant also increases their risk of heart disease. The gene, APOE, encodes for a protein that transports cholesterol in the bloodstream. People with one copy of the undesirable APOE variant, called e4, face double the risk of Alzheimer’s disease than those without that variant. They also have a slightly higher risk of cardiovascular disease. Learning about the heart-related risk appears to spur people to make healthy behavior changes, such as improving their diets, reducing their stress levels, and being more physically active.  (Locked) More »

A stronger heart may help keep your brain young

People with higher levels of cardiovascular fitness may do better on tests that measure memory, motor skills, and executive function (mental skills to manage time, plan and organize, and recall details) than people who aren’t as fit. Exercise delivers extra oxygen to the brain and also seems to stimulate the growth of new cells and blood vessels in the brain. Experts believe that meeting the federal physical activity guidelines may help keep a person’s brain young, or at least slow down the normal decline in age-related thinking skills. (Locked) More »
