Summary

Story summary

A UK Biobank study examined the relationship between rheumatoid arthritis and brain diseases, including depression and dementia, using data from 2,534 RA patients and nearly 490,000 controls.
Researchers analyzed blood markers and diffusion tensor imaging measures and used Cox proportional hazards models to assess brain disease risk.
They applied Mendelian randomization to explore causal links and clarify how RA influences brain health via immunometabolic pathways and structural changes, informing interventions.
