|  | | | | |  In a famous Blue Zone, daily movement was tied to fewer memory complaints Older adults in Sardinian Blue Zone communities who took more daily steps, spent less time sedentary, perceived their physical health more positively, and had greater confidence in their memory reported fewer memory complaints. Sleep efficiency was not significantly associated with memory complaints, and the cross-sectional study cannot establish cause and effect. | |  | | | | |  Neurogenesis stalls in the brains of adults with major depressive disorder, study shows Most of our brain's 100 billion neurons are created before we're born, but the trickle of neurons created in the adult brain hippocampus could be instrumental in preventing depression, suggest findings from a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons. | | | | | | |  Early-life stress rewires brain epigenetics to heighten sensitivity to future stress . Early-life stress increased SETD7 and H3K4me1 in the ventral tegmental area of mice, creating an epigenetically primed state that heightened later transcriptional, neuronal, and behavioral responses to stress. Reducing Setd7 during development lowered H3K4me1 and weakened these stress-sensitizing effects, identifying a mechanism that may help explain how early adversity leaves lasting biological effects. | |

|  | | |  Overreactions to ordinary sensory stimuli - a scratchy shirt tag, a roaring vacuum cleaner, an unfamiliar smell - are commonly associated with autism. | | | | |  How does autism manifest in the brain? Researchers from the University of Southern Denmark and Odense University Hospital have investigated this question in a new study involving 60 adults. | | | | |  A study led by the University of Oxford has identified the brain mechanisms that help us work out whether the consequences we experience are caused by our own actions or by circumstances beyond our control. | | | | |  About one in 10 teenagers experience social anxiety-persistent and disruptive worries about being judged by their classmates and other peers. | | | | |  The first days after childbirth are a time of profound change – not only physically, but emotionally as well. Although the rooming-in model, in which mothers and newborns stay together around the clock, is standard practice in maternity wards, not every woman feels ready to care for her baby independently from the very first hours after delivery. | | | | |  The brain's immune cells are increasingly recognized as key players in Alzheimer's disease, but exactly how they change as the disease develops has remained unclear. | | | | |  A new systematic review published in Frontiers in Psychiatry brings together 68 studies from the first two years after the October 7 attacks, offering insights that extend far beyond Israel into how prolonged conflict, cumulative exposure and continuing threat can shape post-traumatic stress, anxiety, depression and addiction-related outcomes. | | | | |  New research led by the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London, in collaboration with an international partnership of researchers, has, for the first time, compared the genetics of people with binge eating versus those without any eating disorder. | | | | |  A landmark five-year study by Monash University has found psychedelics reorganise brain patterns, giving clinicians powerful new insights into their therapeutic potential. | | | | |  UK Biobank researchers examined whether sugar rationing during pregnancy and the first two years of life was associated with adult sweet-food preferences, sugar intake, brain structure, anxiety, and depression. | | | | | Research from the University of East Anglia shows how our memories change with age and why specific details associated with past events can fade over time. | | | | | A study examined the brains of children at increased risk of developing schizophrenia to determine whether signs of vulnerability can be detected during childhood. | | | | | A five-week training intervention taught college students to better regulate their emotions in response to negative events, a new study finds. | |
