New research shows that psilocybin, the active compound in psychedelic mushrooms, can reduce both chronic pain and pain-related depression by modulating brain circuits rather than acting at the site of injury. In mouse studies, a single dose provided pain relief and mood benefits lasting nearly two weeks by targeting the anterior cingulate cortex.
New research shows psilocybin, often studied as a treatment for mental health disorders, may worsen symptoms of postpartum depression in mice. Mothers given the drug showed more anxiety, avoidance of their pups, and lasting depressive-like behaviors.
A large-scale neuroimaging study of over 10,000 U.S. children reveals that income inequality in society is tied to structural and functional brain changes that predict poorer mental health outcomes. Unlike individual family income, societal inequality impacts children across socioeconomic groups, suggesting that social environments exert powerful biological effects.
A U.S. study combining pollen and suicide data from over a decade shows that high pollen days are linked to a measurable rise in suicide risk. The risk increased incrementally with pollen levels, peaking at a 7.4% rise on the highest days.
A study tracking more than 2,000 Quebec children found that girls who regularly overate in the preschool years were more likely to report anxiety, impulsivity, and hyperactivity during adolescence. The association was not found in boys, pointing to possible sociocultural influences such as closer monitoring and restrictive food environments for girls.
Researchers emphasize that the heart and brain are deeply interconnected, with every heartbeat influencing cognition and emotion within milliseconds. This link helps explain why cardiovascular diseases like hypertension often coincide with mental health disorders such as depression and anxiety.
A new study shows that fluoxetine, better known as Prozac, does more than increase serotonin—it changes how brain cells handle energy and rebuild connections. After two weeks of treatment, parvalbumin interneurons in the prefrontal cortex became less rigid, with mitochondrial energy genes reduced and plasticity genes upregulated.
A large Swedish study of 1.8 million pregnancies found that mental ill health around pregnancy has risen in recent years, with risks spiking after childbirth. While depression and psychosis rates drop during pregnancy, postpartum depression is 20% more likely within weeks 5–15, and psychosis risk is up to seven times higher in the first 20 weeks.
A new study shows that sugary drinks don’t just affect physical health—they may also raise the risk of depression in women by disrupting the gut microbiome. Researchers found that high consumption of soft drinks was linked to both a greater likelihood of major depressive disorder and more severe symptoms, particularly among women.
A new study reveals that recalling positive memories before stepping on stage can significantly boost musicians’ performance. Professional wind instrumentalists who reflected on positive experiences showed higher nervous system activity, greater emotional positivity, and stronger arousal compared to those recalling negative or no memories.
