SYNGAP1 Autistic Behaviors Linked to Seizure Type, Not Frequency

by GLOOM

MHD featured image for SYNGAP1 seizure semiology and autistic behaviors.

A 337-person SYNGAP1-DEE registry preprint found caregiver-reported autistic behavior scores linked most strongly to atypical absence seizures (n = 77; FDR-adjusted p = .001), while peak seizure-frequency ratings were not detectably associated with those behavior scores.1 Research Highlights Seizure type carried the signal: atypical absences were associated with higher caregiver-reported autistic behavior scores in 77 …

Post-Meal Glucose Genetics Linked to Lacunar Stroke Risk

by GLOOM

MHD featured image for post-meal glucose genetics and lacunar stroke risk.

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 …

Autism Polygenic Scores Linked to Lower Neurite Density

by GLOOM

Editorial card showing diffusion-MRI cortical microstructure overlaid on a polygenic-score schematic, illustrating the association between autism PGS and reduced neurite density.

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 …

Migraine Linked to Cognitive Impairment in Chinese MR

by GLOOM

Editorial card showing a brain with migraine pain pathways overlaid on genetic instrument schematic for Mendelian randomization.

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 …

Parkinson’s Metabolite Biomarkers Split 3 Patient Groups

by GLOOM

MHD featured image for Parkinson's disease metabolite biomarkers and patient metabolic subgroups.

A 2026 Parkinson’s disease study used gene-expression data and genome-scale metabolic modeling to predict patient-level metabolite patterns, then separated 104 patients into 3 metabolic subgroups that were partly reproduced in an independent 81-patient validation dataset. Research Highlights Patient-level modeling found heterogeneity: Abdik et al. predicted secretion tendencies for 802 analyzable metabolites across 104 postmortem substantia …

Schizophrenia Risk Genes Reshape Microglial Pruning in CRISPR Screen

by GLOOM

Stylized microglial cell engulfing synaptic material with CRISPR gene-editing elements, representing schizophrenia risk genes altering synaptic pruning.

Schizophrenia’s genetic architecture sits awkwardly between neurons and the immune system. A 2026 CRISPR screen of 30 schizophrenia-associated genes in human microglia-like cells found that several risk genes meaningfully alter how microglia engulf synaptic material, supporting the synaptic-pruning model at the functional gene level.1 Research Highlights 30 schizophrenia risk genes were knocked out one by …

Late-Diagnosed PKU Linked to Depression in Children

by GLOOM

MHD featured image for depression and quality of life in children with phenylketonuria.

A 2026 Egyptian study of 76 children found a sharp mental-health gradient in phenylketonuria (PKU): late-diagnosed children had higher depression scores, lower quality of life, lower IQ, and a 21.4% rate of reported suicidal thoughts. Early-diagnosed children still differed from controls on some functioning measures, but the late-diagnosed group carried the heaviest psychiatric and cognitive …
