A 2026 medRxiv genetic analysis linked type 2 diabetes and 2-hour postprandial glucose — the blood-sugar rise after an oral glucose challenge — to higher lacunar stroke risk, with a stronger direct signal for post-meal glucose than for HbA1c after adjustment for brain small-vessel imaging markers.1 Research Highlights Lacunar stroke was the clearest endpoint: genetically …
A 2025 paper by Gu et al. in Molecular Psychiatry — the largest study of its kind — finds that higher common-variant genetic risk for autism predicts lower cortical neurite density in 31,748 UK Biobank adults and 4,928 ABCD children.1 The effect is small in absolute terms but replicates across cohorts and methods. Research Highlights …
A 2026 study by Bai et al. in Dialogues in Clinical Neuroscience uses Mendelian randomization (MR) — inherited genetic variants as a natural experiment to test causality — and concludes that migraines causally lower cognitive performance in a Han Chinese sample.1 The headline conclusion is plausible; the effect-size numbers in the popular MR shorthand (odds …
For two decades, headlines have linked autism to maternal obesity, depression, anxiety, gestational diabetes, infection, autoimmune disease, and antidepressant use. The studies behind those headlines are well-replicated registry associations. A new design from the Aarhus University iPSYCH group offers the most careful answer yet to what they mean for an individual pregnancy. Most “maternal X …
