Background/Objectives Physical distancing during the COVID‐19 pandemic may have unintended, detrimental effects on social isolation and loneliness among older adults. Our objectives were to investigate 1) experiences of social isolation and loneliness during shelter‐in‐place orders and 2) unmet health needs related to changes in social interactions. Design Mixed‐methods, longitudinal phone‐based survey administered every 2 weeks. Setting Two community sites and an academic geriatrics outpatient clinical practice. Participants 151 community‐dwelling older adults. Measurements We measured social isolation using a 6‐item modified Duke Social Support Index, social interaction sub‐scale, which included assessments of video‐based and internet‐based socializing. Measures of loneliness included self‐reported worsened loneliness due to the COVID‐19 pandemic, and loneliness severity based on the 3‐item UCLA loneliness scale. Participants were invited to share open‐ended comments about their social experiences. Results Participants were on average 75 years old (SD = 10), 50% had hearing or vision impairment, 64% lived alone, and 26% difficulty bathing. Participants reported social isolation in 40% of interviews, 76% reported minimal video‐based socializing, and 42% minimal internet‐based socializing. Socially isolated participants reported difficulty finding help with functional needs, including bathing (20% vs 55%, p = .04). Over half (54%) of participants reported worsened loneliness due to COVID‐19, which was associated with worsened depression (62% vs 9%, p < .001) and anxiety (57% vs 9%, p < .001). Rates of loneliness improved on average by time since shelter‐in‐place orders (4–6 weeks: 46% vs 13–15 weeks: 27%, p = .009), however, loneliness persisted or worsened for a subgroup of participants. Open‐ended responses revealed challenges faced by the subgroup experiencing persistent loneliness, including poor emotional coping and discomfort with new technologies. Conclusions Many older adults are adjusting to COVID‐19 restrictions since the start of shelter‐in‐place orders. Additional steps are critically needed to address the psychological suffering and unmet medical needs of those with persistent loneliness or barriers to technology‐based social interaction.

Background Despite recognition of the neurologic and psychiatric complications associated with SARS-CoV-2 infection, the relationship between coronavirus disease 19 (COVID-19) severity on hospital admission and delirium in hospitalized patients is poorly understood. This study sought to measure the association between COVID-19 severity and presence of delirium in both intensive care unit (ICU) and acute care patients by leveraging an existing hospital-wide systematic delirium screening protocol. The secondary analyses included measuring the association between age and presence of delirium, as well as the association between delirium and safety attendant use, restraint use, discharge home, and length of stay. Methods In this single center retrospective cohort study, we obtained electronic medical record (EMR) data using the institutional Epic Clarity database to identify all adults diagnosed with COVID-19 and hospitalized for at least 48-h from February 1-July 15, 2020. COVID-19 severity was classified into four groups. These EMR data include twice-daily delirium screenings of all patients using the Nursing Delirium Screening Scale (non-ICU) or CAM-ICU (ICU) per existing hospital-wide protocols. Results A total of 99 patients were diagnosed with COVID-19, of whom 44 patients required ICU care and 17 met criteria for severe disease within 24-h of admission. Forty-three patients (43%) met criteria for delirium at any point in their hospitalization. Of patients with delirium, 24 (56%) were 65 years old or younger. After adjustment, patients meeting criteria for the two highest COVID-19 severity groups within 24-h of admission had 7.2 times the odds of having delirium compared to those in the lowest category [adjusted odds ratio (aOR) 7.2; 95% confidence interval (CI) 1.9, 27.4; P = 0.003]. Patients > 65 years old had increased odds of delirium compared to those < 45 years old (aOR 8.7; 95% CI 2.2, 33.5; P = 0.003). Delirium was associated with increased odds of safety attendant use (aOR 4.5; 95% CI 1.0, 20.7; P = 0.050), decreased odds of discharge home (aOR 0.2; 95% CI 0.06, 0.6; P = 0.005), and increased length of stay (aOR 7.5; 95% CI 2.0, 13; P = 0.008). Conclusions While delirium is common in hospitalized patients of all ages with COVID-19, it is especially common in those with severe disease on hospital admission and those who are older. Patients with COVID-19 and delirium, compared to COVID-19 without delirium, are more likely to require safety attendants during hospitalization, less likely to be discharged home, and have a longer length of stay. Individuals with COVID-19, including younger patients, represent an important population to target for delirium screening and management as delirium is associated with important differences in both clinical care and disposition.

Bilingualism is thought to confer advantages in executive functioning, thereby contributing to cognitive reserve and a later age of dementia symptom onset. While the relation between bilingualism and age of onset has been explored in Alzheimer's dementia, there are few studies examining bilingualism as a contributor to cognitive reserve in frontotemporal dementia (FTD). In line with previous findings, we hypothesized that bilinguals with behavioral variant FTD would be older at symptom onset compared to monolinguals, but that no such effect would be found in patients with nonfluent/agrammatic variant primary progressive aphasia (PPA) or semantic variant PPA. Contrary to our hypothesis, we found no significant difference in age at symptom onset between monolingual and bilingual speakers within any of the FTD variants, and there were no notable differences on neuropsychological measures. Overall, our results do not support a protective effect of bilingualism in patients with FTD-spectrum disease in a U.S. based cohort.
