Lockdowns and social distancing have been important and successful strategies to limit the spread of the coronavirus disease 2019 (COVID-19) virus. However, excess deaths related to non-COVID-19 causes have been reported, suggesting issues around availability and use of health services, particularly for people with conditions needing ongoing medical support. In addition, evidence indicates that a range of age-related diseases and frailty are impacted by physical activity and social engagement, both limited in lockdown situations. It is therefore important to learn from the effects of lockdowns in order to limit any impacts, while still protecting people from the infection. This editorial summarizes two research themes at the Centre for Ageing Research at Lancaster University in the UK, one assessing impacts of lockdown for people living with a long-term neurodegenerative condition, Parkinson's disease, and one assessing longitudinal impacts on frailty and wellbeing, with older adults aged over 70, including those living with at least one long-term condition. Uncertainty related to Parkinson's disease and to COVID-19 amplified each other, and cancelled clinical appointments and limitations on physical activity had very significant impacts on wellbeing for this group. In the longitudinal study, frailty was more severe during lockdown periods. While lockdowns reduce spread of the virus, becoming frailer could make older adults more vulnerable to the effects of the virus during these periods. Regular exercise during lockdown had beneficial effects aiding recovery once restrictions relaxed. These studies suggest factors that could lessen negative impacts of future lockdowns. Maintaining physical activity and providing access to health services during periods of lockdown are suggested as priorities.

Objective To explore the role of chronic inflammation in rheumatoid arthritis (RA) on cognition. Methods and analysis Six hundred sixty-one men and women aged ≥55 years who fulfilled the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria for RA were recruited from three healthcare trusts in the United Kingdom (UK) between May 2018 and March 2020. Study participants took part in interviews which captured sociodemographic information, followed by an assessment of cognition. RA specific clinical characteristics were obtained from hospital medical records. Participants were cognitively assessed using the Montreal Cognitive Assessment (MoCA) and were classified as cognitively impaired if they scored ≤27/30 points. Linear regression analyses were conducted to identify which demographic and clinical variables were potential predictors of cognitive impairment. Results The average age of participants was 67.6 years and 67% (444/661) were women. 72% (458/634; 95% CI 0.69 to 0.76) of participants were classified as cognitively impaired (MoCA≤27). Greater cognitive impairment was associated with older age (p = .006), being male (p = .041) and higher disease activity score (DAS28) (with moderate (DAS28 > 3.1) (p = 0.008) and high (DAS28 > 5.1) (p = 0.008)) compared to those in remission (DAS28 ≤ 2.6). There was no association between MoCA score and education, disease duration, RF status, anti-cyclic citrullinated peptide (anti-CCP) status, RA medication type or use of glucocorticoids or non-steroidal anti-inflammatory drugs (p > 0.05). Conclusion This study suggests that cognitive impairment is highly prevalent in older adults with RA. This impairment appears to be associated with higher RA disease activity and supports the concept that chronic systemic inflammation might accelerate cognitive decline. This underlines the importance of controlling the inflammatory response.

IntroductionPossession of one or two e4 alleles of the apolipoprotein E (APOE) gene is associated with cognitive decline and dementia risk. Some evidence suggests that physical activity may benefit carriers of the e4 allele differently.MethodWe conducted a systematic review and meta-analysis of studies which assessed APOE differences in the association between physical activity and: lipid profile, Alzheimer's disease pathology, brain structure and brain function in healthy adults. Searches were carried out in PubMed, SCOPUS, Web of Science and PsycInfo.ResultsThirty studies were included from 4,896 papers screened. Carriers of the e4 allele gained the same benefit from physical activity as non-carriers on most outcomes. For brain activation, e4 carriers appeared to gain a greater benefit from physical activity on task-related and resting-state activation and resting-state functional connectivity compared to non-carriers. Post-hoc analysis identified possible compensatory mechanisms allowing e4 carriers to maintain cognitive function.DiscussionThough there is evidence suggesting physical activity may benefit e4 carriers differently compared to non-carriers, this may vary by the specific brain health outcome, perhaps limited to brain activation. Further research is required to confirm these findings and elucidate the mechanisms.
