Exergames -- exercise combined with virtual reality -- might give a cognitive boost to older people more than regular workouts, researchers have found. A study published in the February issue of the American Journal of Preventive Medicine focused on 79 men and women ages 58 to 99 who did three months of regular exercise on a stationary bicycle or three months of exergaming on cybercycles. The cybercycles had a virtual reality display that let riders take part in 3-D tours and compete against a ghost rider avatar.

Chronic pain can bring on depression , problems of memory and concentration, and general brain fog -- a fact well known to many of the 50 million American adults who live with pain that has settled in for a long stay. But a study published Wednesday finds that changes in the brain that come with chronic pain can be reversed when the hurt is treated effectively. The study , published in the Journal of Neuroscience, looked at sufferers of chronic low-back pain--a substantial slice of those with daily pain -- and compared their brain responses to cognitive tests and their brains' structures before and after they got treatment.

The cellphone conversations going on around us — in the grocery store, mall, airport, elevator, on the bus, etc. — are by now ubiquitous. But they still feel intrusive. A new study suggests our brains simply don't like these one-sided chats. Researchers at Cornell University conducted a series of tests to gauge people's reactions when exposed to four background noise settings: silence, a monologue, a conversation between two people and half a conversation (called a halfalogue)

Type 2 diabetes is linked with a number of health problems, but a new study finds that older diabetics who have high blood pressure, gait and balance problems or think their health is poor may be at higher risk for cognitive problems. Researchers looked at 13 potential variables that could affect cognition, including grip strength, blood pressure, involvement in physical activities, social engagement, gait and balance, and a subjective measure of a person's health. The study participants, from British Columbia, included 41 people with Type 2 diabetes age 55 to 81, and a matched group of 458 healthy people that served as a control.

Middle-aged men who smoke suffered more rapid cognitive decline than peers who have never smoked or who have been ex-smokers for at least 10 years, researchers reported Monday in the Archives of General Psychiatry . Smoking is known to be a risk factor for dementia in the aged, but the extent to which it is a risk factor for cognitive problems earlier in life is less-well understood, wrote the team. Led by Severine Sabia of University College London's Department of Epidemiology and Public Health, the researchers looked at data collected from 5,099 men and 2,137 women.

There's a phrase that has haunted America for decades, one fraught with failure: "Breaking the cycle of poverty. " Despite the ongoing efforts of government and a host of private foundations, income inequality continues to grow and the poor are ever more likely to remain poor. Many factors favor the rich getting richer while the poor stagnate. The wealthy benefit from economies of scale, as the best prices and lowest interest rates are more readily available to those who least need them.
