Polygenic Scores May Improve Accuracy of ADHD Diagnosis when Combined with Standard Diagnostic Scales (2024 Study)

by

The ADHD polygenic score (PGS) adds slight yet statistically significant value to existing ADHD diagnostic tools, though it currently lacks clinical utility. Highlights: Study Overview: Researchers tested if adding a genetic score (ADHD PGS) to traditional diagnostic tools (ASRS and WURS scales) and family history could better predict ADHD. Improvement in Diagnosis: Adding the ADHD …

Genetics Linked to Intelligence (IQ), Health, Longevity: Polygenic Scores

by

Intelligence predicts health and mortality – but why? New research reveals some genes are implicated in both. Key facts: Intelligence test scores predict mortality, illnesses, and health behaviors. Higher scores indicate lower risk. Both intelligence and health/disease outcomes are highly polygenic – many genetic variants of small effect contribute. Genetic correlations exist between intelligence and …

Genetics & Specific Cognitive Abilities: Highly Heritable (50%)

by

General intelligence, known as g or IQ, has long been the focus of cognitive genetics research. But what about more specific cognitive abilities, the building blocks that make up IQ? A sweeping new meta-analysis of over 740,000 twins surprisingly suggests: Specific cognitive abilities (SCA) like reading, math and processing speed are just as heritable as …
