Telehealth Support for Dementia Caregivers During the COVID-19 Pandemic: Lessons Learned From the NYU Family Support Program.

OBJECTIVES: In response to the needs of dementia caregivers during the COVID-19 pandemic, the NYU Langone Alzheimer's Disease and Related Disorders Family Support Program (FSP) quickly transitioned to providing most services online. To understand how dementia caregivers experienced FSP services after the switch to video telehealth, we conducted qualitative interviews of spouse or partner dementia caregivers. PARTICIPANTS: Ten participants were recruited from a convenience sample of dementia spouse or partner caregivers who used one or more online FSP services offered during the pandemic. DESIGN: Caregivers engaged in semi-structured interviews held via videoconference between May and June 2020. Qualitative analysis of interviews was conducted according to the principles of framework analysis. RESULTS: Caregivers reported high satisfaction with the FSP pre-pandemic and continued to feel supported when services were provided online. They transitioned to video telehealth services with little difficulty. CONCLUSIONS: While video telehealth is frequently cited as beneficial for those in rural communities, socioeconomically disadvantaged groups, or homebound individuals, our findings suggest that video telehealth is also advantageous for dementia caregivers, given their unique barriers, including lack of time due to caregiving responsibilities, lack of respite care for the person with dementia, and the additional burdens of travel time to access in-person services.

Longitudinal study: understanding the lived experience of couples across the trajectory of dementia.

BACKGROUND: The longitudinal study, "Couples Lived Experiences," focuses on whether and how relationship characteristics of older couples change with the cognitive decline of one member of the couple, and how these changes affect each individual's emotional and physical health outcomes. Until now, most psychosocial research in dementia has focused either on the person with dementia (PWD) or the caregiver separately. The previous literature examining relationship characteristics and their role in outcomes for the caregiver and PWD is scant and suffers from methodological issues that limit the understanding of which relationship characteristics most influence outcomes for caregivers and care-receivers and what other factors may mitigate or exacerbate their effects. METHODS: We will enroll 300 dyads and collect information via online interviews of each member of the couple, every 6 months for 3 years. Relationship characteristics will be measured with a set of short, well-validated, and reliable self-report measures, plus the newly developed "Partnership Approach Questionnaire." Outcomes include global quality of life, subjective physical health, mental health (depression and anxiety), and status change (transitions in levels of care; i.e., placement in a nursing home). Longitudinal data will be used to investigate how relationship characteristics are affected by cognitive, functional, and behavioral changes, and the impact of these changes on health outcomes. Qualitative data will also be collected to enrich the interpretation of results of quantitative analyses. DISCUSSION: Psychosocial interventions have demonstrated effectiveness in promoting the wellbeing of PWD and their caregivers. The knowledge gained from this study can lead to the development or enhancement of targeted interventions for older couples that consider the impact of cognitive and functional decline on the relationship between members of a couple and thereby improve their wellbeing. TRIAL REGISTRATION: This study has been registered with ClinicalTrials.gov. ClinicalTrials.gov Identifier is: NCT04863495 .

Neural memory of the genioglossus muscle during sleep is stage-dependent in healthy subjects and obstructive sleep apnoea patients.

KEY POINTS: In most patients with obstructive sleep apnoea (OSA), there is a spontaneous resolution of the breathing disorders during slow wave sleep (SWS) for yet unknown reasons related to non-anatomical factors. Some recently identified forms of neural memory specific of upper airway muscles may play a role in this phenomenon. In the present study, we show for the first time that a form of memory of the genioglossus (tongue) muscle is greatly enhanced during SWS compared to non-rapid eye movement stage 2 sleep. The present study represents a step forward in understanding the mechanisms responsible for the spontaneous development of stable breathing during SWS in OSA patients and may help the discovery of novel therapeutic strategies for this disease. ABSTRACT: Several studies have shown that obstructive sleep apnoea (OSA) improves during slow wave sleep (SWS) for reasons that remain unclear. Recent studies have identified forms of neural memory such as short-term potentiation or after-discharge that can occur in response to upper airway obstruction. Neural memory may play a role in the development of stable breathing during SWS by increasing upper airway muscles activity in this sleep stage. We hypothesize that the after-discharge of the genioglossus muscle following upper airway obstruction is enhanced during SWS compared to non-rapid eye movement stage 2 (N2). During sleep, we performed five-breath drops in continuous positive airway pressure (CPAP-drop) to simulate obstructive events and reflexively activate the genioglossus. Immediately afterwards, CPAP was returned to an optimal level. Once the post-drop ventilation returned to eupnoea, the genioglossus after-discharge was measured as the time it took for genioglossus activity to return to baseline levels. In total, 171 CPAP-drops were analysed from a group of 16 healthy subjects and 19 OSA patients. A mixed-model analysis showed that after-discharge duration during SWS was 208% (95% confidence interval = 112% to 387%, P = 0.022) greater than during N2 after adjusting for covariates (ventilatory drive, CPAP levels). There was also a non-significant trend for a -35% reduction in after-discharge duration following an arousal vs. no-arousal from sleep (95% confidence interval = -59.5% to 5%, P = 0.08). Genioglossus after-discharge is two-fold greater in SWS vs. N2, which could partly explain the breathing stabilization described in OSA patients during this sleep stage.
