TL;DR: Women who reported 10+ brain injuries from a partner performed on a speed test like someone about 21 years older than their actual age. They scored about 11 years “older” than survivors with no brain injury; the study of 207 women found a link, not proof that the injuries caused the difference. Key Findings …
TL;DR: A 2026 pooled analysis in CNS Drugs combined two six-week trials of adults whose depression hadn’t responded well enough to an antidepressant. Adding the antipsychotic lumateperone instead of a placebo raised the share of people with side effects from 45.1% to 68.1% and the share who quit because of them from 0.8% to 8.7%. …
TL;DR: A 2026 meta-analysis in Neurological Sciences pooled 10 studies that gave people with Parkinson’s disease, tested while on their dopamine medication, and healthy adults the same “think of as many ideas as you can” tasks. On average, the two groups scored about the same, with neither a creative boost nor a clear deficit. Key …
TL;DR: A meta-analysis pooling 63 studies and 265,079 people found that cannabis users had about twice the odds of committing violence as non-users (2.05 times in the general population, 2.49 times among psychiatric patients). The gap shrank to 1.17 times in studies that followed people over time. The design shows an association, not that cannabis …
TL;DR: In an online survey of 126 mothers of toddlers in Taiwan, mothers who reported more depressive symptoms also tended to describe their toddler’s sleep as more of a problem and to report longer times to fall asleep. The link with perceived sleep problems showed up in families where the toddler shared a sleeping surface …
TL;DR: In a small German study of 24 refugee women with trauma symptoms, scores on three symptom questionnaires stayed flat during an 8-week wait, then dropped after 8 weekly dance movement therapy sessions. The group’s average PTSD checklist score slipped just under the usual clinical cutoff. There was no separate comparison group, so the study …
TL;DR: A review of 17 randomized trials found that women who exercised had lower depression scores than women given usual care, both during pregnancy and after birth. The evidence is rated low to very low certainty, and the studies varied a lot. For anxiety during pregnancy, the review found no clear difference. Key Findings Depression …
TL;DR: In a controlled Dutch feeding trial, 41 healthy young adults ate a diet made almost entirely of ultra-processed foods for two weeks, twice. Afterward, the gut hormones that help signal fullness responded to a test meal about the same as they had on the participants’ usual diets. Hunger and fullness ratings shifted only a …
TL;DR: In a crossover trial of 119 adults living near busy highways, a month with a real HEPA air purifier did not clearly speed up a thinking test across the whole group. Among adults 40 and older, though, participants finished the harder test 12% faster after the real-purifier month than after the fake-purifier month. That …
TL;DR: Researchers used wrist trackers to estimate the sleep stages of 95,559 British adults, then followed their hospital records for about 9 years. Adults who spent more time in REM sleep had lower risk of 83 different diagnoses, and adults sleeping under 5 hours a night had higher risk of many conditions than those sleeping …
