Researchers have conducted the world’s first meta-analysis of the relationship between PTSD and dementia. Encompassing over a million subjects the study found PTSD can double a person’s risk of developing dementia in their senior years.

Researchers at the Mayo Clinic have developed a test, called the Gut Microbiome Health Index, that can predict a person’s general health status by measuring the levels of 50 gut microbial species.

Whether it occurs in a car, plane, boat or VR environment, motion sickness is no fun. According to new research, though, it's possible for people to "train their brain" out of the condition, potentially reducing the symptoms by more than half.

In order to see if an antidepressant works, patients have to take the drug for at least a month. New research, however, suggests that by monitoring a sleeping patient's brainwaves, the effectiveness of an antidepressant can be gauged in a week.

The idea alone of a massage might do wonders for some people’s stress levels, but a new study has delved into the physiological details of how these short and sweet treatments can kick the body’s relaxation systems into gear.

A new CDC study has found restaurant dining to be the most commonly shared activity amongst a number of adults with COVID-19. The CDC study suggests eating at a restaurant is an especially high-risk activity during this ongoing pandemic.

New research has shown depression can be detected by monitoring a person's heart rate over a 24-hour period. The small study needs more verification but it points to a biomarker that could be easily integrated into patient monitoring systems.

Following a swift independent investigation, large-scale trials for a COVID-19 vaccine developed by scientists at the University of Oxford are recommencing across the UK after a suspected adverse reaction triggered a global halt to trials last week.

In order to track how someone's body position changes as they sleep, they typically have to be rigged up with sensors, or filmed by a video camera. MIT's new BodyCompass system, however, offers a third alternative that many people may prefer.

Three years ago, scientists from the University of Arizona reported that exposure to green light appeared to reduce neuropathic pain in rats. Now, the researchers believe that such light could also be used to treat migraine headaches in humans.

COVID-19 vaccine trials conducted by Oxford University and AstraZeneca have been paused, according to a new report. One participant has fallen ill with an unknown illness, prompting investigations into whether it’s an adverse reaction to the vaccine.

A UC Berkeley study has found an association between poor sleep and accumulation of the toxic proteins thought to cause Alzheimer’s disease. The researchers suggest poor sleep could be a way to predict those at risk of developing the degenerative disease.
