4 Your Health: art helps bedside manner; friends really do think alike; brain injuries link to dementia

Posted: Updated:

Traumatic brain injuries increase the risk of dementia, even decades later.

That's according to a new long-term study conducted in Sweden. People who suffered a brain injury were four to six times more likely to develop dementia within the first year. And while that risk declined over time it was still significant more than 30 years after the injury.

Patients with more severe, or multiple, brain injuries had the highest* risk of developing dementia.

Friends have like-minded brains

Researchers, at Dartmouth College, monitored a group of students as they watched a series of video clips. Friends had the most similar brain response to the videos followed by friends of friends and then those with no social ties.

The arts helping doctors relate

Exposure to arts and humanities in medical school may benefit future doctors.

A new Tulane University study found med students who took art, music, and theater classes, had more empathy and tolerance than their peers. These students were also less likely to feel physically and emotionally burned out.
