Summary: A new study suggests that oral microbiota transmission between newlywed couples may influence the onset of depression and anxiety symptoms. Researchers observed that healthy spouses of partners with insomnia, depression, and anxiety developed similar mental health symptoms and microbiota profiles within six months of marriage. The study found strong correlations between shared bacterial strains, … Read more
Summary: New research reveals that small, shallow grooves in the human brain—called tertiary sulci—are closely tied to reasoning ability and brain connectivity in children and adolescents. These uniquely human folds appear to bring critical brain regions closer together, enhancing communication and cognitive function. In an fMRI study, deeper tertiary sulci in the lateral prefrontal and … Read more
Summary: Scientists have engineered dozens of adeno-associated virus (AAV) systems that ferry genes to specific neuron and glial subtypes in the brain and spinal cord with unprecedented accuracy. Powered by AI-selected DNA “light switches,” the vectors can switch on therapeutic or research genes only in targeted cells, eliminating the need for transgenic animals and enabling … Read more
Summary: A groundbreaking study has shown that multiple sclerosis (MS) can now be accurately diagnosed with a specialized MRI scan, eliminating the need for invasive and often painful lumbar punctures. The scan, which takes just 8 minutes, detects brain lesions centered on veins—a hallmark of MS—using a technique called T2*-weighted MRI. Researchers introduced a simple … Read more
Summary: A new study has uncovered a biological link between inflammation and motivational deficits in people with schizophrenia, identifying a promising treatment target for symptoms that current medications fail to address. Higher levels of the inflammatory marker C-reactive protein were associated with reduced activity in brain regions involved in reward and motivation, such as the … Read more
Summary: Infants hospitalized with severe COVID-19 mount an immune response that looks entirely different from that of adults or older children. Researchers found both interferon responses and inflammation were elevated simultaneously—something never before observed in other viral infections. T and B cells in these infants were still naïve yet highly activated, and some even produced … Read more
Summary: A new study finds that elevated cortisol levels in midlife are linked to increased brain amyloid deposition—a key marker of Alzheimer’s disease—specifically in post-menopausal women. Researchers tracked 305 cognitively healthy individuals over 15 years and discovered that high cortisol predicted amyloid buildup later in life, but only among women who had gone through menopause. … Read more
Summary: New research suggests that personality testing could help tailor treatment for people with bipolar disorder by predicting who is more likely to experience recurrent depression or struggle with daily life functioning. Analyzing data from over 2,500 individuals, researchers identified combinations of personality traits—called personality styles—that either increase or protect against long-term mental health risks. … Read more
Summary: Frontotemporal dementia (FTD), a common form of early-onset dementia, is often misdiagnosed due to its overlapping symptoms with psychiatric and neurological disorders. In a new NIH-funded study, researchers identified key protein changes in spinal fluid that may serve as the first specific biomarkers for FTD in living patients. These proteins point to problems in … Read more
