          Abstract

          Rheumatoid Arthritis (RA) is a form of arthritis characterized by joint pain, stiffness, swelling and deformity. There has been plethora of researches in the area of rheumatoid arthritis which focused on immune system, genetic predisposition and newer treatment modalities. Researchers have also examined the cognitive decline, physical deficits and their interrelationship in patients with RA. Among several psychological aspects depression, anxiety and stress emerge as significant psychological co morbidity. RA is a multifactorial, chronic, inflammatory disease primarily affects physical functioning as well as psychological aspects. Pain, fatigue, duration of disease, disease activity and functional disability are very common in rheumatoid arthritis which is leading cause of psychological distress and functional disability. Various types of neuropsychological battery were used to assess the decline in specific areas like attention, executive functioning, visuo-spatial learning, verbal learning/memory etc. These functions were compared with other type of arthritis disease. Also, various other factors like depression, cardiovascular diseases, other systemic and chronic disease and concomitant drugs intake etc. also affected cognitive functioning in Rheumatoid Arthritis patients. The objective of this review was to identify and explore the rates and types of cognitive impairment in RA. This present review paper systematically examines and summarizes the cognition related decrement in arthritis patients. Multiple research articles between 1990 to 2018 were searched. These reviews were evaluated and synthesized using a narrative and descriptive approach.

          Cumulative impact of sustained economic hardship on physical, cognitive, psychological, and social functioning.

          J. Lynch, Jay R. Kaplan, S J Shema (1997)
          Although the relation between low income and poor health is well established, most previous research has measured income at only one time. We used income information collected in 1965, 1974, and 1983 from a representative sample of adults in Alameda County, California, to examine the cumulative effect of economic hardship (defined as a total household income of less than 200 percent of the federal poverty level) on participants who were alive in 1994. Because of missing information, analyses were based on between 1081 and 1124 participants (median age, 65 years in 1994). After adjustment for age and sex, there were significant graded associations between the number of times income was less than 200 percent of the poverty level (range, 0 to 3) and all measures of functioning examined except social isolation. As compared with subjects without economic hardship, those with economic hardship in 1965, 1974, and 1983 were much more likely to have difficulties with independent activities of daily living (such as cooking, shopping, and managing money) (odds ratio, 3.38; 95 percent confidence interval, 1.49 to 7.64), activities of daily living (such as walking, eating, dressing, and using the toilet) (odds ratio, 3.79; 95 percent confidence interval, 1.32 to 9.81), and clinical depression (odds ratio, 3.24; 95 percent confidence interval, 1.32 to 7.89) in 1994. We found little evidence of reverse causation -- that is, that episodes of illness might have caused subsequent economic hardship. Sustained economic hardship leads to poorer physical, psychological, and cognitive functioning.

            The impact of chronic pain in the community.

            B Smith, A. M. Elliott, W A Chambers … (2001)
            Chronic pain is known to be very common in the community. Less is known about the epidemiology of more significant or severe chronic pain. The impact of chronic pain in the community, in terms of general health, employment and interference with daily activity, has not been quantified. The aim of this study was to describe the prevalence and distribution in the community of chronic pain defined as 'significant' and 'severe', and to explore the impact of chronic pain on health and activity. A questionnaire survey was carried out of a sample drawn from the general population in the Grampian region of SCOTLAND: Questionnaires were sent to a random sample of 4611 individuals aged 25 years and over, stratified for age and gender, selected from the practice lists of 29 general practices (total practice population 136,383). The study instrument included a case definition questionnaire, from which were identified individuals with 'any chronic pain' (pain of at least 3 months duration). The instrument also included a level of expressed need questionnaire and the chronic pain grade questionnaire, from which were derived definitions for 'significant chronic pain' (based on the reported need for treatment and professional advice) and 'severe chronic pain' (based on reported intensity and pain-related disability). The SF-36 general health questionnaire and demographic questions were also included. Of the sample, 14.1% reported 'significant chronic pain', and this was more prevalent among women and older age groups. A total of 6.3% reported 'severe chronic pain', and this was more common in older age groups. On multiple logistic regression modelling, female gender, housing tenure, employment category and educational attainment were found to be independently associated with both 'significant' and 'severe' chronic pain. The presence of 'any', 'significant' and 'severe' chronic pain had progressively more marked adverse associations with employment, interference with daily activities and all measured dimensions of general health. Comparison of the epidemiology of 'significant chronic pain' and 'severe chronic pain' with 'any chronic pain' allows an understanding of the more clinically important end of the chronic pain spectrum. These results support the suggestion that chronic pain is multidimensional, both in its aetiology and in its effects, particularly at this end of the spectrum. This must be addressed in management and in further research.

              Anxiety and depression in patients with rheumatoid arthritis.

              Süleyman Koca, A. Ozturk, Osman Mermi … (2007)
              Rheumatoid arthritis (RA) mostly follows a painful, progressively disabling course, and individuals with RA experience more psychological distress than healthy individuals. The objective of the present study is to examine the prevalences of accompanying anxiety and depression in RA cases. The study included 82 RA cases and 41 age- and sex-matched healthy volunteers as the control group. Psychiatric examinations of all cases of the patient and control groups were performed according to DSM-IV criteria. Hamilton Anxiety Scale or Hamilton Depression Scale was applied to those who were found to have anxiety or depression. Total prevalence of anxiety, depression, and mixed anxiety-depressive disorder was found to be 70.8% (n=58) in the patient group and 7.3% (n=3) in the control group, and the difference was significant (p<0.001). Of the RA patients, 41.5% (n=34) was found to have depression, 13.4% (n=11) anxiety, and 15.9% (n=13) mixed anxiety-depressive disorder. The disease duration in patients with anxiety was shorter than the RA patient with depression (p<0.05). The disease duration was positively correlated with the degree of depression and negatively correlated with the degree of anxiety (r=0.341, p<0.05; r=-0.642, p<0.05, respectively). The results of our study suggest that prevalences of anxiety and mainly depression, increase in RA cases. When the clinical picture in RA cases becomes complicated with anxiety or depression, some problems at patients' adaptation and response to treatment may be possible. RA cases should be monitored for accompanying anxiety or depression during follow-up.
