Challenges

Mortgages, kids, job pressures: It's no secret that the older we get — and the more responsibilities we take on — the more we worry. Blame it on your brain: an October 2009 review in the international journal Biochimica et Biophysica Acta shows that as we age, neurological shifts can increase cautiousness, anxiety and negative thinking while boosting levels of stress hormones.
"This can happen to anyone and is part of normal aging," says Anthony Doran, a psychologist and professor of neuropsychology at Johns Hopkins University. "It's a result of the gradual breakdown of regenerative processes that occur in many tissues, including the brain."
Roughly 20 percent of older adults experience Generalized Anxiety Disorder (GAD) — excessive worry that interferes with daily life — compared with just 3 to 7 percent of the general population, according to the review. The actual percentage of older adults with GAD may be even higher, since the condition is often undiagnosed.
Fortunately, you can fight back. Just as you can take steps to reduce your risk of cancer, you can combat anxiety and improve brain function. Here are four steps to keep your mind healthy, positive and ready for new adventures.
