UK researchers have analyzed rheumatoid arthritis (RA) patients from the UK Clinical Practice Research Database and shown that chronic conventional DMARD (cDMARD) use was associated with 40% lower risk of dementia (nearly 50% with methotrexate use).
They compared 3876 cDMARD users to 1938 nonusers among incident RA and found a reduced risk of dementia (hazard ratio: 0.60; 95% confidence interval: 0.42-0.85). The effect was strongest in methotrexate users (hazard ratio: 0.52; 95% confidence interval; 0.34-0.82).
These results suggest a new potential therapeutic role for DMARDs and the possible contribution of inflammation on dementia.
