Heart patients with dementia are more likely to get pacemakers than heart patients who do not have cognitive difficulties
Running - even just a few minutes a day - appears to lower a person's risk of dying from cardiovascular disease. Researchers in Iowa looked at 55-thousand adults during a 15 year period. They found runners who ran consistently lowered their risk the most. But people who ran less than an hour, and people who ran fewer miles at a slower pace--  still had a 45 percent lower  risk of death from heart disease or stroke compared to non-runners.
Heart patients with dementia are MORE likely to get pacemakers than heart patients who do NOT have cognitive difficulties. That's the surprising finding of a new study out of the University of Pittsburgh. Researchers found those WITH dementia were 1.6 times more likely to get the implant than those who had no memory problems. Researchers say their finding calls into question whether the aggressive treatment is appropriate for patients with such a disabling and incurable disease.
And a new study finds preschoolers with special needs benefit when they are surrounded by peers who have strong language skills. Researchers from Ohio found the opposite was also true -- when special needs children were surrounded by children with weak language skills, their language development suffered.
