ABSTRACT
Introduction@#Cognitive impairment (CI) in patients with systemic lupus erythematosus (SLE) presents with or without overt signs of central nervous involvement. The prevalence of CI is variable, ranging from 19-80%. It is often overlooked, leading to high healthcare costs and productivity loss. The usual tools for detection are expensive, time-consuming and not locally available. Detection of CI using the Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment Test (MoCA) is more clinically relevant and practical. The objectives of this study are to determine the prevalence of CI in SLE patients using MMSE/MoCA, to determine the degree of impairment in the different cognitive domains, and to characterize patients with CI in terms of disease activity, education, and employment.@*Methods@#This is a cross-sectional study of 62 SLE patients, 19 years or older, at a rheumatology clinic. Demographic and disease characteristics were collected. The validated Filipino versions of the MMSE/MoCA test were administered. Descriptive and non-parametric statistics were applied.@*Results@#Most patients are female (96.77%), below collegiate level of education (58.06%), and unemployed (70.97%). Mean disease duration is 8.92 (SD±7.03) years. Mean age at diagnosis is 28 (SD±10.30) years. Hypertension is the most common co-morbidity. Most have low lupus disease activity or are in remission (80.65%). Most are on prednisone (72.58%), with an average dose of 11.88mg/day (SD±10.66). The prevalence of CI is 38.71% (MMSE-P) and 77.42% (MoCA-P). The presence of CI is not related to educational level, employment, and disease activity.@*Conclusion@#Cognitive impairment (CI) is common in this cohort of SLE patients. Disease activity, level of education and employment do not seem to affect its occurrence. The MMSE-P and MoCA-P are rapid tools to assess the presence of CI and should be used in clinical practice to improve the quality of care for patients with lupus.
