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.

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.

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.

Concussion research has yet to turn up therapies that can diminish the consequences of a mild traumatic brain injury or shorten the duration of its symptoms, the nation's leading group of neurologists concluded on Monday. But in athletics, there is one step that can avert lengthening symptoms or exacerbating damage from a blow to the head, the American Academy of Neurology wrote: Take the athlete out of the game or off the practice field when a concussion is suspected, and delay his or her return to play until the all-clear has been issued by a trainer or physician skilled in diagnosing and treating brain injury.

Diagnosing Alzheimer's disease will one day be accomplished with biological markers, such as tests of blood or spinal fluid. Already several biomarker tests are in development. But a new study shows that, for now, the old-fashioned cognitive tests using pen and paper are the most accurate. Researchers looked at 116 people with mild cognitive impairment who developed Alzheimer's disease in two years, 204 people with mild cognitive impairment that did not develop the disease and 197 cognitively healthy people.
