Caffeine has been associated with a reduced risk of developing Parkinson’s disease, but a new study says a coffee jolt might not be good for people already diagnosed with the brain disorder. Consuming caffeine appears to blunt the brain’s ability to use dopamine, the hormone that lies at the heart of Parkinson’s symptoms, researchers reported… read on > read on >
California skateboarder Jared Hager has become the first person to receive a transparent skull replacement, which allows doctors to better view the function of his brain. The window has allowed doctors to both monitor his progress and test new and better scanning methods for assessing brain health. Hager, 39, of Downey, Calif., sustained a traumatic… read on > read on >
America’s college students seem to be more stressed than ever, with a new report finding a sharp rise in cases of post-traumatic stress disorder (PTSD) and acute stress disorder (ASD) on campuses across the country. In a “national sample of U.S. college students, we found a notable increase in the prevalence of PTSD and ASD,”… read on > read on >
