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.
For the first time, lab-grown mini brains have revealed how neurons misfire in schizophrenia and bipolar disorder. Using machine learning to analyze electrical activity, researchers identified distinct firing patterns that served as biomarkers, distinguishing patient-derived organoids from healthy ones with over 90% accuracy.
A new study shows that both mothers and fathers significantly shape their adolescent children’s social anxiety, but in different ways. Warmth, affection, and acceptance from either parent reduce anxiety, while rejection, coldness, and controlling behaviors heighten it.
