In mouse models of Rett syndrome -- which in humans is seen overwhelmingly in females -- researchers have demonstrated how failure of Mecp2, the mouse equivalent of the human gene of the same name, has biological consequences that prevent adult females from learning how to gather newborn pups in the days immediately following the pups' birth. They reversed the defect.
Teenagers who play video games for more than four hours a day suffer from symptoms of depression, but frequent use of social media and instant messaging may mitigate symptoms of game addiction in these teens, new Johns Hopkins Bloomberg School of Public Health-led research suggests.
New research has found concussions accelerate Alzheimer's disease-related brain atrophy and cognitive decline in people who are at genetic risk for the condition. The findings, which appear in the journal Brain, show promise for detecting the influence of concussion on neurodegeneration.
This study shows how high estrogen release during the estrus cycle increases the pleasure felt via the brain's reward pathway
Experiments in mice by researchers at Johns Hopkins suggest that if the goal is to ease or extinguish fearful emotional memories like those associated with post-traumatic stress disorder, alcohol may make things worse, not better. Results of their study demonstrate, they say, that alcohol strengthens emotional memories associated with fearful experiences and prevents mice from pushing aside their fears.
Study suggests that CDC guidelines for who should be on Preexposure prophylaxis (PrEP) don't go far enough because current standards could miss some people who should be on it. Working with the Los Angeles LGBT Center, UCLA-led researchers developed an online PrEP risk calculator that may fill that gap.
In a new study of indoor tanning and skin cancer risk, the use of indoor tanning among non-heterosexual black male teens was found to be nearly equal to that of heterosexual white females. The study led by San Diego State University researcher Aaron Blashill, was recently published in the journal JAMA Dermatology.
Now you can find help for depression and anxiety on your smartphone as quickly as finding a good sushi restaurant. A novel suite of 13 speedy mini-apps called IntelliCare significantly reduced depression and anxiety in study participants, who used the apps on their smartphones up to four times a day. The reductions of 50 percent in anxiety and depression are comparable to results expected in clinical practice using psychotherapy or with antidepressant medication.
Scientists at the Virginia Tech Carilion Research Institute have discovered that observing fear in others may change how information flows in the brain. The finding in a rodent model may have bearing on people who suffer post-traumatic stress disorder.
Patients who take medication for depression report more side effects if they also suffer from panic disorder, according to a new study led by researchers from the University of Illinois at Chicago published in the Journal of Clinical Psychiatry.
