Researchers have identified a biomarker in human platelets that tracks the extent of depression.
Scientists investigating the DNA outside our genes - the 'dark genome' - have discovered recently evolved regions that code for proteins associated with schizophrenia and bipolar disorder.
Scientists report that norepinephrine, a fundamental chemical for brain performance, is locally regulated in a brain region called the visual cortex.
Middle-aged women who practiced self-compassion had lower risk of developing cardiovascular disease, irrespective of their blood pressure, insulin resistance and cholesterol levels.
Use of assisted reproductive techniques (ART) does not lead to poorer mental health in children across adolescence and young adulthood, according to a large observational study. The study found a slightly higher risk of obsessive-compulsive disorder for those born after ART but this was explained by parental background factors.
Computer- and smartphone-based treatments appear to be effective in reducing symptoms of depression, and while it remains unclear whether they are as effective as face-to-face psychotherapy, they offer a promising alternative to address the growing mental health needs spawned by the COVID-19 pandemic, according to new research.
Neuroscientists have discovered a set of brain cells that influence the motivation of mice to perform tasks for rewards. Increasing the cells' activity makes a mouse work harder or more vigorously. The neurons come with a feature that prevents the mouse from overdoing it and becoming addicted to the reward. The findings reveal new possible therapeutic strategies for treating mental illnesses like depression that impair motivation.
The causes of psychiatric disorders are poorly understood. Now there is evidence that a wide range of early onset psychiatric problems (from depression, anxiety and addictions to dyslexia, bulimia, and ADHD) may be largely due to the combination of just three factors. The first is biological --i n the form of individual variability in the brain's dopamine reward pathway. The second is social -- and points to the important role of early childhood neglect or abuse. And the third is psychological--and relates to temperament, and particularly to tendencies toward impulsivity and difficulty controlling emotions. These findings have implications for understanding both the causes of a wide range of psychiatric disorders and the features worth targeting in early intervention efforts.
Psychologists have revealed a surprising finding that could help those who struggle with schizophrenia: While people with the illness tend to manage low-level negative emotions, they struggle to do so as those negative emotions increase.
Researchers analyzing 21 years of data found that the percentage of psychiatrist visits involving psychotherapy has declined by half -- dropping to only 21.6 % of patient visits. Over half of U.S. psychiatrists no longer practice any psychotherapy at all. The study found that for rural, Black, Hispanic, and Medicaid patients psychiatrists' provision of psychotherapy was exceedingly rare.
