Aging is more a winding path than a downhill slalom. Changes in brain function as well as our outlook on life can influence the journey ahead. If you forget a name or two, take longer to finish the crossword, or find it hard to manage two tasks at once, don't assume you're on the road to dementia. What you're experiencing is age-related changes in the way your brain works. And in many ways it's actually working better.

MRIs taken of a teenager working through a problem show a lot of activity on one side of the prefrontal cortex, the region we use for conscious reasoning. In middle age, the other side of the brain begins to pitch in a little. In seniors, both sides of the brain are sharing the task equally. A host of studies in the l

Nearly 70% of Americans report getting insufficient sleep on a regular basis, and approximately 20% of Americans suffer from chronic pain. Recently, the intersection between these two conditions has become more apparent. The association between sleep deficiency or poor quality sleep and increased perception of pain from various medical conditions is well known; poor sleep quality predicts greater intensity of pain from conditions such as back strain, arthritis, and fibromyalgia. In many cases, the relationship is bi-directional. For example, my colleagues and I have documented that heartburn is worse after a poor night's sleep, and conversely heartburn can re
