A 2026 PLOS One computational study linked Trichostatin A to 949 predicted targets and 8 machine-learning-selected Alzheimer’s disease core genes, but 100 ns molecular dynamics simulations suggested the compound did not stably bind those candidate proteins.1 That makes the result more useful as an epigenetic network hypothesis than as evidence for a near-term Alzheimer’s drug. …
A 2026 Spanish Rett Syndrome Behavior Questionnaire validation preprint found strong test-retest reliability across 51 caregivers, including an intraclass correlation coefficient of 0.907 and a 31-person short-interval subset with Pearson r2 = 0.8663.1 The result supports Spanish-language research access, but it is linguistic validation rather than proof that the scale diagnoses Rett syndrome or measures …
A 2026 study of 250 mothers of children with intellectual and developmental disabilities (IDDs) found that family burden was strongly tied to lower social support, lower family quality of life, and lower happiness. In the structural model, the burden-happiness link was explained by perceived support and family quality of life rather than a direct burden-to-happiness …
A self-localized ultrafast pencil beam is not a brain treatment, but it could become useful imaging infrastructure for neuroscience and drug-delivery research. In an arXiv preprint, Cao et al. generated a stable ultrafast beam inside a standard multimode fiber and used it for volumetric multiphoton imaging of intact mouse enteric nervous tissue and a live …
A 2026 mouse study found that long-term CoQ10 exposure reduced working-memory errors in Purkinje-cell-specific Drp1-deficient mice, tying the behavioral rescue to Coa6 binding and support for mitochondrial respiratory-chain function.1 The result supports a narrow mechanistic CoQ10-Coa6 pathway under neuronal mitochondrial dysfunction while leaving human memory-supplement claims untested. Research Highlights Working memory improved in a mouse …
A 2026 Molecular Psychiatry analysis from the Rhineland Study found that blood-derived microRNA signatures were associated with hippocampal brain structure: 6 microRNAs linked cross-sectionally to left hippocampal volume, and 5 different microRNAs linked longitudinally to hippocampal atrophy rates.1 The result is biomarker-discovery evidence for brain aging, not a ready dementia blood test. Research Highlights Baseline …
A 2025 Science Advances mouse study found a more brain-dependent metformin mechanism than the usual liver-gut framing suggests: low-dose metformin lost its glucose-lowering effect when brain Rap1 signaling could not be reduced, and 36 of 47 ventromedial-hypothalamus SF1 neurons responded directly to metformin.1 Research Highlights Low-dose metformin needed brain Rap1: Control mice lowered glucose after …
