New research using genome editing technology has allowed scientists to create a model and assess a gene mutation associated with neuropsychiatric disorders in humans. The study has revealed how the mutation functions in the brain and affects anxiety and sociality.
With the advent of rapid whole genome sequencing, children presenting with an intellectual disability or developmental delay are recommended to have their DNA sequenced to identify the underlying genetic cause. Researchers have now published the results of an analysis of data from almost 2,800 young people with rare genomic variants -- changes to their DNA -- that are associated with intellectual disability.
It is well known that whole-body exposure to high frequency ultrasound increases brain activity in humans. However, little is known about its impact and associated mechanisms on emotional states like depression. Now researchers have recently demonstrated the anti-depressant effects of ultrasound exposure in a rodent model of depression. Their findings shed light on the potential of ultrasound exposure as a non-invasive treatment for mental disorders.
It may feel like an anvil hanging over your head, but that looming deadline stressing you out at work may actually be beneficial for your brain, according to new research. The study found that low to moderate levels of stress can help individuals develop resilience and reduce the risk of developing mental health disorders, like depression and antisocial behaviors. Low to moderate stress can also help individuals to cope with future stressful encounters.
Being exposed to work requirements in order to receive food stamps from the U.S. government significantly increased use of mental health care resources for depression and anxiety, a new study has found. The policy's negative effects occurred much sooner for women than men.
People who reported experiencing discrimination more than once a week early in the pandemic had seventeen-fold increased odds of moderate to severe depressive symptoms and ten-fold increased odds of suicidal ideation, according to a new study.
A new analysis dives into the use of service dogs by U.S. veterans who have posttraumatic stress disorder (PTSD), illuminating factors and mechanisms that may underlie the mental health effects of these relationships.
