What's the connection between the gut and brain health?

Gut bacteria may influence our emotions and cognitive capabilities. For example, some bacteria make oxytocin, a hormone the body produces that encourages increased social behavior. Other bacteria make substances that cause symptoms of depression and anxiety. Still others make substances that help people to be calmer under stress. Gut bacteria also have been shown to influence people's vulnerability to certain brain diseases, including Alzheimer's disease, Parkinson's disease, and autism. For example, a substance found in the brains of people with Parkinson's disease (synuclein) is made by gut bacteria and can travel via nerves from the gut to the brain.

Do you need aspirin therapy?

The medical world agrees that daily aspirin can help people with cardiovascular disease lower their risk of heart attacks and strokes. However, most people over age 70 without cardiovascular disease should avoid aspirin as a way to prevent a heart attack or stroke. Even if a person has taken aspirin for a long time as primary prevention of heart disease, it's time to talk to your doctor about potentially stopping it.

Scroll smarter to protect your mental health

Research has found associations between social media use and negative mental health effects in both youth and adults. These ill effects may reflect the particular ways people use social media. People may have a healthier online experience if they focus on interacting with others, rather than just scrolling through posts. Some additional strategies that can help improve the experience are avoiding posts from unpleasant people, discussing contentious subjects in person rather than online, and using social media to enhance real-life relationships.

New details about loneliness and dementia risk
