People in Southern California with relatively high exposures to wildfire smoke over a decade also had significantly higher risks for dementia, a new study warns.

After a hit to the head or a fall, people, especially seniors, can develop a dangerous pooling of blood and fluid between the brain's surface and it's protective covering, the dura.

These "subdural hematomas" typically require surgery to fix, but a new study suggests a better approach, one that makes sure repeat surgeries aren't required.

A person’s brain performs an intricate juggling act while watching a movie, a new study demonstrates.

Scans showed that 24 different brain networks and regions engage from scene-to-scene, based on hard it is to follow the movie or what’s currently on the screen, researchers reported.

The brain’s “executive control” networks -- regions related to plannin...

Alzheimer’s disease patients prescribed fistfuls of daily drugs are at greater risk of harm, a new study warns.

Are people with autism less able to "read" the nefarious intent of criminals, leaving them more vulnerable to scams or coercion into criminal activity?

It's been a common notion among trial lawyers, the Australian researchers behind a new report say, but it's not grounded in any real evidence.
