A study led by UCLA Health scientists finds that highly creative people's brains exhibit an atypical approach to connectivity, enabling them to bypass traditional hubs and form distant connections. This 'road less traveled' pattern is more efficient for creative thinking but may not be optimal in all situations.
A study published in International Journal of Geriatric Psychiatry found that antidepressants were associated with a lower risk of suicide among residents aged 75+, who had a significantly increased risk if taking sleep medication or having a history of self-harm. The research highlights the need for early recognition and quality care ...
A new study finds that maternal feedback, not biological predisposition, influences reward-related brain activity in children of mothers with clinical depression. The research suggests that interventions coaching parents to encourage positive emotions may have a powerful impact on child development.

The opioid crisis in the US has reached epidemic levels, with over 100,000 drug overdose deaths reported for the first time. The US Centers for Disease Control and Prevention attributes the rise to abuse of synthetic opioid fentanyl and the COVID-19 pandemic.
A recent study found an increase in intentional drug overdose deaths among young people aged 15-24, older adults aged 75-84, and non-Hispanic Black women. Despite a downward trend in overall deaths, these subgroups saw a rise in intentional overdose death rates, with women ages 45 to 64 having the highest rates.

The study involved 2,511 families with children aged 6-14 and showed that girls with externalizing disorders were more likely to be held back a grade.
A University of Ottawa study found that trying to suppress emotions with a poker face or smile has little impact on mood and memory, contradicting past research. Instead, participants used alternative strategies like changing their perspective to cope with distressing moments.
Researchers at Massachusetts General Hospital have developed a portable brain imaging procedure using functional near-infrared spectroscopy (fNIRS) to detect acute impairment from THC intoxication. The technique shows promise in distinguishing between impairment and mild intoxication, with accuracy confirmed by machine learning models.

Racial and ethnic disparities are also evident, with Black, Hispanic, and Asian adults facing higher odds of certain conditions.
Middle-aged women with higher self-compassion had thinner carotid artery walls and less plaque buildup, linked to lower cardiovascular disease risk. The findings persisted even when controlling for behaviors and psychological factors.
A large observational study found that children conceived through assisted reproductive techniques (ART) have generally good mental health throughout adolescence and young adulthood. However, those born after ART had a slightly elevated risk of obsessive-compulsive disorder, which was explained by parental background factors.
A study published in PNAS found that individuals with severe schizophrenia have a higher number of rare mutations than those with typical forms of the illness. This discovery could lead to more precise treatments for this chronic disease, which affects over 3 million Americans.
A study in young psychiatric outpatients with episodic or chronic depression found differences in one-carbon and energy metabolism, which could aid in diagnosis and targeted treatments. The preliminary results suggest potential mechanisms behind chronicity, highlighting the need for larger cohorts to confirm findings.
