Both President Biden and former President Trump have experienced public memory lapses. Experts say that's common for people of their age and not necessarily a sign of cognitive impairment or dementia.

Now that there are drugs to treat Alzheimer's, blood tests to detect it will likely become an attractive, low-cost option to decide who can get treatment. Some tests are more accurate than others.

Our brains have a remarkable ability to take a mix of sounds and translate them into meaning. A team of scientists monitored the brain activity of people as they listened to English sentences.

A study suggests that deep brain stimulation can improve focus and attention in people recovering from a traumatic brain injury. This could offer a path for those living with debilitating impairments.

Two brain circuits help regulate salt intake: One adjusts salt cravings, the other determines whether we find salty food delicious or disgusting. (Story aired on ATC on Nov. 20, 2023.)

Two different brain circuits help regulate salt intake, according to a study in the journal Cell. One adjusts salt cravings, the other determines whether we find salty food delicious or disgusting.
