Background/Purpose: Only few studies investigated the prevalence and risk factors of cognitive impairment in patients with rheumatoid arthritis (RA), however, results are controversial. Therefore we performed this study to determine the prevalence and risk factors of cognitive impairment and their association with RA disease activity.
Methods: Patients with RA and osteoarthritis (OA) were recruited from 3 university hospitals and physical, psychosocial, laboratorial, and medication statuses were assessed. Patients under 45 years old or with illiteracy were excluded. The activity and functional status of RA were assessed by Disease activity score (DAS)-ESR and Routine Assessment of Patient Index Data 3 (RAPID 3) score. Cognitive function was evaluated by Korean version of Mini-Mental State Examination (MMSE-K). Cognitive impairment was defined as MMSE-K scores ≤ 23.
Results: A total of 506 RA and 202 OA patients were recruited. Cognitive impairment was observed in 10.5%in RA and 13.4% in OA (P=0.272). In subgroup analysis between RA patients with cognitive impairment (n=53) or not (n=453), education level (OR 0.72, 95% CI 0.64-0.80), marriage status (OR 2.12, 95% CI 1.02-4.41), and high disease activity (OR 2.84, 95% CI 1.08-7.48) were independently predicted cognitive impairment after multivariate analysis controlling for age, hypertension, exercise, RAPID 3 score, fatigue, depression, and medication use. In subgroup analysis between RA patients with high disease activity (DAS28-ESR>5.1, n=55) or without (n=448), high disease activity was strongly associated with cognitive impairment (25.5% vs 8.5%, P=0.001). The education level was 63.8±9.96 and 62.1±8.51 (P=0.250) and age was 7.9±4.42 and 8.8±3.82 (P=0.111). In addition, DAS28-ESR score showed negative correlation with MMSE-K score (ρ=-0.110, P<0.05).
Conclusion: High disease activity is strongly associated with cognitive impairment in patients with RA. Thus, controlling disease activity may help preserving cognitive function in RA.
