Summary

Story summary

Researchers from Aarhus University identified rare genetic variants in MAP1A, ANO8, and ANK2 that increase ADHD risk up to 15 times.
The study analyzed genetic data from nearly 9,000 ADHD patients and 54,000 controls, showing the variants disrupt dopaminergic and GABAergic neurons involved in attention.
Carriers also show lower IQ scores and poorer educational and socioeconomic outcomes.
The findings may guide future ADHD treatments and highlight the disorder's genetic underpinnings.
