Jul 30, 2018 - Poor mental health may cost businesses nearly as much as physical health problems, according to researchers. A single extra poor mental health day in a month was associated with a 1.84 percent drop in the per capita real income growth rate, resulting in $53 billion less total income each year.
Jul 30, 2018 - A majority of young adults with severe mental illness -- bipolar disorder, schizophrenia or major depression -- consider religion and spirituality relevant to their mental health, according to a new study.
Jul 20, 2018 - Greening vacant urban land significantly reduces feelings of depression and improves overall mental health for the surrounding residents, researchers show in a new randomized, controlled study. The findings have implications for cities across the United States, where 15 percent of land is deemed ''vacant'' and often blighted or filled with trash and overgrown vegetation.
Jul 19, 2018 - A group of researchers has discovered that neural inflammation caused by our innate immune system plays an unexpectedly important role in stress- . This insight could potentially lead to the development of new antidepressants targeting innate immune molecules.
Jul 19, 2018 - A preliminary study shows an intervention program that includes a personalized app could make a difference: Researchers found the rate of attempted suicides by teenagers who received the intervention was halved compared to those who received the standard care during their hospitalization.
Jul 19, 2018 - Contrary to popular belief across college campuses, attention deficit hyperactivity disorder (ADHD) medications may fail to improve cognition in healthy students and actually can impair functioning.
Jul 17, 2018 - Teens who spend lots of time using digital devices are prone to psychiatric problems, reports a team of scientists in a new study. Children who are heavy users of digital devices are twice as likely as infrequent users to show symptoms of attention-deficit/hyperactivity disorder (ADHD), the study finds.
Jul 17, 2018 - A new study found that young adults who had a parent incarcerated during their childhood are more likely to skip needed healthcare, smoke cigarettes, engage in risky sexual behaviors, and abuse alcohol, prescription and illicit drugs. These findings have a potentially broad impact, as more than five million US children have had a parent in jail or prison.
Jul 11, 2018 - Stressful situations affect the brain and body differently in people with schizophrenia compared to people without the mental illness or individuals at high risk for developing psychosis, a new study shows. The relationship between two chemicals released when people experienced stress -- one released in the brain and the other in saliva -- differs ...
Jul 9, 2018 - The origins of the violent behavior are multifactorial and respond to the interaction of several factors --biological, cultural, social, etc. -- which can modify the expression of the human behavior. Now, an international study has identified forty genes related to aggressive behavior in humans and mice.
Jul 3, 2018 - Researchers have recently begun to realize that biological sex plays a key role in disease risk. Sex plays a role in hypertension, diabetes, arthritis -- and in many neurological and psychiatric disorders. Depression and anxiety affect females more, while neurodevelopmental disorders, including autism spectrum disorders, early onset schizophrenia, ...
Jul 2, 2018 - Maternal use of the antidepressant fluoxetine (Prozac) can alter the brain circuits in her offspring that control behaviors reminiscent of autism spectrum disorder, suggests a study in mice. These results have no immediate bearing on the treatment of depression in pregnant women.

Jun 22, 2018 - A new study shows that people with schizophrenia account for more than one in 10 cases of suicide in Ontario, and that young people are disproportionately affected. People with schizophrenia also had more contact with the health care system, pointing to an opportunity to intervene. The researchers emphasize the need for early suicide risk assessments to reduce risks.
Jun 21, 2018 - Researchers explored the genetic connections between brain disorders at a scale far eclipsing previous work on the subject.

A new study has found psychedelics, specifically DOI, DMT, and LSD, can change brain cells in rats and flies, making neurons more likely to branch out and connect with one another. The work supports the theory that psychedelics could help to fight depression, anxiety, addiction, and post-traumatic stress disorder.
