UNIVERSITY OF MARYLAND SCHOOL OF MEDICINE Substance use disorder affects 20 million Americans, and more than 100,000 people died from a drug overdose in 2021, according to the Centers for Disease Control and Prevention. While the medication methadone has the strongest evidence-based effectiveness to prevent relapse, about half of patients drop out of their treatment within...

Credit: Salk Institute Brains are like puzzles, requiring many nested and co-dependent pieces to function well. The brain is divided into areas, each containing many millions of neurons connected across thousands of synapses. These synapses,...

By Michael Irving April 11, 2023 Scientists may have a new weapon against the historically tricky-to-treat stomach bug norovirus Depositphotos If you’ve ever eaten something questionable and then paid for it from both ends for a few days, chances are you’ve had a norovirus. But this common pathogen is surprisingly tricky to treat or prevent....

by Yale School of Public Health Credit: Unsplash/CC0 Public Domain A Yale School of Public Health study has found that older persons with mild cognitive impairment (MCI), a common type of memory loss, were 30% more likely to regain normal cognition if they had taken in positive beliefs about aging from their culture, compared to those...
by Karolinska Institutet Credit: CC0 Public Domain Alzheimer’s disease begins decades before the onset of any symptoms, such as memory loss. Consequently, early diagnosis increases the chances of slowing the disease down with drugs. A new study on an inherited form of the disease shows that a protein called GFAP is a possible biomarker for very...
