TL;DR: A 2026 preprint in medRxiv warned that a standard Alzheimer’s disease biomarker-clock analysis can create a countdown paradox, where later biomarker-clock ages appear linked to faster mild cognitive impairment onset because of the way remaining time is calculated. Key Findings 100% false positives in simple null simulations: The standard countdown analysis rejected the null …
TL;DR: A 2026 review and activation-likelihood estimation study in European Journal of Pain found that the dorsolateral prefrontal cortex (dlPFC), a frontal control region, was repeatedly engaged in acute pain, chronic pain, and placebo analgesia, mainly across Brodmann areas 8, 9, and 46. Key Findings 138 studies included: The review screened 4810 deduplicated records and …
TL;DR: A 2026 randomized follow-up study in Maternal & Child Nutrition found no overall hair-cortisol difference at ages 9-11 after early-life small-quantity lipid-based nutrient supplementation, but children whose mothers had 0-5 years of schooling had lower cortisol if they received SQ-LNS. Key Findings No overall cortisol shift: Usable hair cortisol data from 680 children showed …
TL;DR: A 2026 study in eLife found that infants’ brains responded more strongly to structured children’s music than shuffled music by 3 months, while clearer music-linked movement patterns appeared mainly by 12 months. Key Findings 79 infants tested: Researchers recorded electroencephalography (EEG), a scalp measure of brain electrical activity, and video-based body movement in 3 …
TL;DR: A 2026 mouse study in Nature Communications found that deleting ankyrin-2 (Ank2) from hippocampal astrocytes left recent memory intact but weakened remote memory, pointing to astrocyte structure as part of how memories stay stable over time. Key Findings Recent recall stayed intact: Mice lacking astrocytic Ank2 performed normally in the day-1 contextual fear memory …
TL;DR: A 2026 narrative review in Clinical Drug Investigation argued that desvenlafaxine, a serotonin-noradrenaline reuptake inhibitor (SNRI), may be a first-line major depressive disorder option for selected patients, especially when fatigue, cognitive complaints, polypharmacy, or tolerability concerns shape the treatment choice. Key Findings Review plus consensus: The source combined a PubMed-based narrative review with a …
TL;DR: A 2026 preprint in medRxiv found that stroke survivors doing motor imagery showed changing brain-heart coupling across rehabilitation sessions, especially between cardiac sympathetic activity and electroencephalography (EEG) beta-band network clustering. Key Findings 15 stroke survivors: Researchers analyzed two cohorts with upper- or lower-limb motor impairment after stroke. 2 motor-imagery protocols: Dataset 1 used gait …
TL;DR: A 2026 crossover study in Clinical Physiology and Functional Imaging found that adding electrical muscle stimulation to low-intensity resistance exercise improved inhibitory control in young men, while stimulation alone showed a delayed 15-minute benefit. Key Findings 17 young men: Participants completed low-intensity resistance exercise, electrical muscle stimulation alone, and combined low-intensity exercise plus stimulation …
TL;DR: A 2026 pilot randomized trial in Nursing in Critical Care found that an 8-week home-based program combining exercise with computerized cognitive training was feasible in 36 ICU survivors and produced larger reductions in patient-reported post-intensive care syndrome severity than attention control, while exploratory cognitive and quality-of-life effect sizes generally favored the combined program over …
TL;DR: A 2026 study in European Archives of Psychiatry and Clinical Neuroscience linked sustained quetiapine treatment with better high-working-memory cognitive performance in schizophrenia spectrum disorder, but the genetic tests did not support the proposed remyelination-moderation mechanism. Key Findings 166 matched pairs: The extended PsyCourse analysis included 166 quetiapine-treated schizophrenia-spectrum patients and 166 age- and sex-matched …
