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 …
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 …
Suicide remains a leading cause of death worldwide, with its prevention a top priority for both public health initiatives and individual care strategies. Recent research in the US Army offers new insights into the genetic underpinnings of suicide attempts, suggesting that polygenic risk scores (PRS) could become a valuable tool in identifying individuals at risk. …
Executive functioning (EF) is a cognitive cornerstone essential for goal-directed behaviors and complex thinking. Recent research leveraging the massive UK Biobank dataset has shed new light on the genetic underpinnings of EF, revealing its distinct genetic profile from intelligence (IQ) and its intricate link with psychiatric disorders. This study underscores the importance of EF in …
Recent research has shed light on the complex relationship between Autism Spectrum Disorder (ASD) and alterations in the cortical surface area (SA) of the brain. By analyzing large-scale genetic data, scientists have begun to unravel the intricate genetic correlations and causal connections between these two factors. Highlights: Genetic Correlation Identified: The study found a nominal …
Recent advancements in genetics have illuminated the complex interplay between genetic factors and early vocabulary development in children. A comprehensive meta-genome-wide association study (meta-GWAS) delves into how genetic variations influence the acquisition of vocabulary in infancy and toddlerhood. This research not only enhances our understanding of language development but also sheds light on its genetic …
In a study utilizing data from the TOMMORROW trial, researchers have embarked on a novel exploration of genetic associations with cognitive change in older individuals. Employing a genome-wide association study (GWAS) approach, they’ve identified specific genetic variants linked to cognitive dynamics, providing new insights into the genetic underpinnings of cognitive change with aging. Highlights: Novel …
