“…Here, we observed that healthy older adults (HOA) showing higher COVID-19 pandemic impact had lower scores in verbal uency. Throughout the pandemic, signi cant cognitive decline has been described in large cohorts of healthy, pre-frail, and frail older adults 33 , particularly regarding memory and recall function 34 . We add up to the literature suggesting an association between the degree of pandemic impact and cognitive performance, particularly verbal uency, in cognitively preserved older adults.…”

The COVID-19 pandemic greatly impacted people's lives, including social interactions, physical and mental health, and the use of technology. This impact may endure even after the vaccination, especially in more vulnerable populations such as older adults. Here, we measured the global impact of the COVID-19 pandemic on older adults with or without mild cognitive impairment (MCI). We used a questionnaire comprising: living arrangements, physical health, information about the pandemic, behaviors adopted in the face of pandemic-related restrictions, financial situation, mental health, and changes in life activities. We primarily asked if the impact would be associated with demographics, cognition, depression/anxiety, and/or quality of life. Secondarily, we wondered whether the pandemic impact would differ between participants assessed before and after the vaccination. In cognitively healthy older adults, a higher pandemic impact was associated with worse cognitive performance and quality of life and increased symptoms of anxiety and depression. In older adults with MCI, higher pandemic impact was associated with increased depressive symptoms. Only healthy older adults had significantly lower pandemic impact scores after vaccination. We conclude that the perceived pandemic impact on older adults was associated with cognition, anxiety, depression, and quality of life. Since the effect of vaccination on decreasing the perceived pandemic impact was not observed in older adults with MCI, interventions to reduce the pandemic impact on this population should be developed and recommended even after the vaccination.

BackgroundCognitive frailty describes the co‐occurrence of cognitive impairment and physical frailty and is classified into reversible and irreversible phenotypes. Data on the impact of COVID‐19 pandemic imposed lockdowns, locally known as the Movement Control Order (MCO), on the psychological status of cognitively frail older adults remain scarce. Therefore, this study aimed to determine the relationship between depression, anxiety, stress and cognitive frailty among older adults during the MCO.MethodParticipants aged above 60 years from three ageing cohorts in Malaysia were interviewed virtually. The Fatigue, Resistance, Ambulation, Illness and Loss of Weight scale, blind Montreal Cognitive Assessment, 15‐item Geriatric Depression Scale, anxiety subscale of Depression, Anxiety and Stress Scale and four‐item Perceived Stress Scale measured frailty, mild cognitive impairment (MCI), depression, anxiety and stress, respectively.ResultsCognitive frailty data were available for 870 participants, age (mean ± SD) = 73.44 ± 6.32 years and 55.6% were women. Fifty‐seven (6.6%) were robust, 24 (2.8%) had MCI, 451 (51.8%) were pre‐frail, 164 (18.9%) were pre‐frail+MCI, 119 (13.7%) were frail and 55 (6.3%) were frail+MCI. There were significant differences in depression and anxiety scores between the controlled MCO and recovery MCO. Using multinomial logistic regression, pre‐frail (mean difference (95% confidence interval, CI) = 1.16 (0.932, 1.337), frail (1.49 (1.235, 1.803) and frail+MCI (1.49 (1.225, 1.822)) groups had significantly higher depression scores, frail (1.19 (1.030, 1.373)) and frail+MCI (1.24 (1.065, 1.439)) had significantly higher anxiety scores and pre‐frail (1.50 (1.285, 1.761)), frail (1.74 (1.469, 2.062)) and frail+MCI (1.81 (1.508, 2.165)) had significantly higher stress scores upon adjustments for the potential confounders. The MCO was a potential confounder in the relationship between depression and prefrail+MCI (1.08 (0.898, 1.340)).ConclusionFrail individuals with or without MCI had significantly higher depression, anxiety and stress than those who were robust. Increased depression and stress were also observed in the pre‐frail group. Interventions to address psychological issues in older adults during the COVID‐19 pandemic could target prefrail and frail individuals and need further evaluation.

“…One study by Noguchi et al [22] in older adults found more subjective cognitive impairments as the pandemic continued in those participants that became or remained socially isolated. In a longitudinal study that started following older adults already before the pandemic, a steeper cognitive decline with time was observed since the pandemic, especially for memory and recall of word lists [23], [24]. Moreover, higher anxiety symptoms in older adults were related to higher impairments in subjective cognitive functioning [25].…”

In earlier survey research, we observed a severe impact of the first peak of the COVID-19 pandemic on the subjective wellbeing, sleep and activity of adults aged 65 years or older in Flanders, Belgium. The impact on subjective cognitive functioning, however, was limited. Since then, periods of lockdown and periods with less strict regulations alternated, but social distancing remained, especially for older adults. To study the longer-term impact of the pandemic on wellbeing and cognitive functioning, we re-assessed the older adults from the first measurement moment (n = 371) in a second (June-July 2020) and third (December 2020) wave of the survey. Results indicated that wellbeing fluctuated with the severity of the pandemic. Results for self-reported cognitive functioning were mixed. While participants indicated a slightly better general cognitive functioning at the end of the study, experienced problems with most cognitive subdomains significantly increased over time. The presence of depressive and anxiety symptoms influenced the longer-term impact of the pandemic on wellbeing and cognitive functioning. Our study shows the long-lasting impact of the pandemic on the wellbeing and cognitive functioning of older adults, without full recovery from the first wave.
