This heart rhythm disorder is linked to thinking and memory problems. But anti-clotting drugs may lower the risk.

Bouts of atrial fibrillation, or afib — a rapid, chaotic heartbeat — make some people feel lightheaded and dizzy, while others don't notice any symptoms. But the most serious threat of this condition is the higher risk of stroke among people with afib compared with those without the disorder (see "Blood clot dangers, large and small"). Now, there's a growing recognition that people with afib also face an increased risk of thinking and memory problems — even if they do not experience a stroke.

Known as cognitive impairment, these problems include trouble remembering, learning new things, concentrating, or making routine decisions. The presumed underlying cause? Tiny blood clots that cause "silent" (that is, unrecognized) strokes and gradually injure parts of the brain involved with cognition.

Mindfulness is the practice of purposely focusing your attention on the present moment, such as how the air smells and feels as you walk your dog, or how a bite of bread tastes with dinner. The ultimate goal is to help shift your thoughts away from your usual preoccupations toward an appreciation of the moment and a larger perspective on life.

Scientific examination of mindfulness shows that it can improve both physical and psychological symptoms and create positive changes in health attitudes and behaviors.

Strengths are built-in capacities for certain thoughts, feelings, and behaviors. Everyone has these capacities to one degree or another. Your particular pattern of strengths is part of what makes you unique.

When you play from your strengths, you are likely to feel more energetic and perform better than when you are trying to use a capacity that comes less naturally. For example, one person trying to influence a local school board to ban soft drink sales might have the strength to speak up forcefully and clearly at a general meeting (despite the almost-universal fear of public speaking). Another person strong in team-building might feel uncomfortable speaking out in a meeting but could successfully build consensus among parents, nutritionists, and others to weigh the issue and come to a decision.

We all experience pain in our lives, but can the cure be worse than the condition? In this seminar, Harvard Medical School experts explore the science of pain, the realities of prescription drug dependence and new discoveries and treatments that may lead to better, safer pain management.

Each spring, Harvard Medical School's Office of Communications and External Relations organizes a series of four free "mini-med school" classes for the general public in the heart of Boston's Longwood Medical Area. At the end of the seminar series, participants who attend three out of the four sessions receive a certificate of completion. Topics are selected for their appeal to a lay audience and have included the human genome, nutrition, sleep dynamics and health care access. Faculty from Harvard Medical School and its affiliate hospitals volunteer their time to present these lectures to the community.

Benefits such as mental stimulation and social engagement are associated with staving off chronic disease.

Punching a time clock is still part of the regular routine for an increasing number of older adults. They're staying employed or going back to work, even though they're beyond the traditional retirement age of 65.

"For well over 100 years, men had been retiring at earlier and earlier ages. Something shifted in the 1990s, and they began working longer. The story for women is different. They weren't always in the labor force. But now we see employment rates rising for women at every age," says Nicole Maestas, an associate professor of health care policy at Harvard Medical School. She studies the economics of aging, health, and disability.

These strategies may offer greater protection.

While there's no cure for Alzheimer's disease, ongoing research has suggested there may be ways to lower your risk.

"Much of the existing science supports how certain behavioral changes made in middle age can protect people as they grow older," says Dr. Kirk Daffner, director for the Center for Brain/Mind Medicine at Harvard-affiliated Brigham and Women's Hospital. "However, there is evidence that adopting certain healthy lifestyle habits can benefit older adults too."
