TL;DR: A 2026 Nature Neuroscience study found that multiple sclerosis lesions rich in lipid-filled foamy microglia had a molecular profile tied to faster disability progression, cerebrospinal-fluid oxylipins, and a druggable lipid enzyme called MAGL. Key Findings 250 MS donors: Across Netherlands Brain Bank records, a higher proportion of lesions with foamy microglia correlated with faster …
TL;DR: A 2026 mouse study in Alcohol: Clinical and Experimental Research found that chronic intermittent ethanol plus repeated forced-swim stress left mice drinking more alcohol months later and impaired reversal learning in midlife, alongside locus coeruleus signs of oxidative stress and weaker adrenergic autoregulation. Key Findings Persistent effects reached midlife: The experiment followed 55 C57BL/6J …
TL;DR: A 2026 open-label study in Communications Medicine found that Bacillus Calmette-Guerin (BCG) immunotherapy changed cerebrospinal-fluid immune-cell responses and Alzheimer-related biomarkers in 23 older adults. Key Findings Small trial context: 2 related 1-year open-label trials enrolled 23 adults aged 55 or older at one academic medical center. BCG dosing was simple: Participants received 2 intradermal …
TL;DR: A 2026 review in Translational Psychiatry argues for a biologically meaningful inflammatory depression subgroup, with CRP, IL-6, TNF-alpha, glial activation, kynurenine metabolism, and synaptic plasticity linking immune signaling to symptoms and treatment response. Key Findings One-third treatment gap: The review notes that current pharmacological treatments fail to produce adequate responses in approximately one-third of …
TL;DR: A 2026 Neuron study proposed that developing brain cells can gain positional information partly from lineage, because cells descended from the same progenitor tend to stay near one another as tissue grows. Key Findings Lineage as position signal: The model argues that shared ancestry can help cells infer where they are without relying only …
TL;DR: A 2026 methodology paper in European Archives of Psychiatry and Clinical Neuroscience describes EMBER-MDD, a research-only multi-omic study designed to find treatment-resistance and esketamine-response biomarkers in about 420 adults with major depressive disorder. Key Findings About 420 adults: EMBER-MDD will analyze biomaterials from approximately 420 adults with major depressive disorder. 210 versus 210 design: …
TL;DR: A 2026 study in Nature Machine Intelligence reported that a textile soft hand exoskeleton with thumb control and surface electromyography (sEMG) intent detection restored practical grasping in one person with severe ALS-related hand paralysis and helped the most severely impaired stroke participants more than moderately impaired users. Key Findings 97% intent sensitivity: A non-invasive …
TL;DR: A 2026 cohort study in PLOS One found that higher fasting plasma vitamin C levels were independently associated with larger MRI-measured gray matter and stronger default mode network (DMN) structural connectivity in 2,044 older adults, but the cross-sectional design cannot show that vitamin C caused the brain differences. Key Findings Large MRI cohort: The …
TL;DR: A 2026 feasibility study in the Journal of Activity, Sedentary and Sleep Behaviors found that pregnant participants could use a research-grade accelerometer plus text-message sleep diaries across much of pregnancy, although third-trimester wear declined. Key Findings 10 pregnant participants: The pilot recruited Kaiser Permanente Northern California members at 10 weeks’ gestation and followed them …
TL;DR: A 2026 study in Brain, Behavior, & Immunity – Health linked composite inflammatory biomarkers during pregnancy and postpartum with postpartum anxiety symptoms, but the strongest associations ran in the unexpected direction of lower anxiety risk at higher biomarker levels. Key Findings 14,419 postpartum women were screened: Researchers calculated inflammatory biomarkers during the 2nd trimester, …
