- We investigated the use of Alzheimer's disease (AD) biomarkers in European Alzheimer's Disease Consortium centers and assessed their perceived usefulness for the etiologic diagnosis of mild cognitive impairment (MCI). We surveyed availability, frequency of use, and confidence in diagnostic usefulness of markers of brain amyloidosis (amyloid positron emission tomography [PET], cerebrospinal fluid [CSF] Aβ42) and neurodegeneration (medial temporal atrophy [MTA] on MR, fluorodeoxyglucose positron emission tomography [FDG-PET], CSF tau). The most frequently used biomarker is visually rated MTA (75% of the 37 responders reported using it "always/frequently") followed by CSF markers (22%), FDG-PET (16%), and amyloid-PET (3%). Only 45% of responders perceive MTA as contributing to diagnostic confidence, where the contribution was rated as "moderate". Seventy-nine percent of responders felt "very/extremely" comfortable delivering a diagnosis of MCI due to AD when both amyloid and neuronal injury biomarkers were abnormal (P < .02 versus any individual biomarker). Responders largely agreed that a combination of amyloidosis and neuronal injury biomarkers was a strongly indicative AD signature.

- BACKGROUND: Prior to COVID-19, >90% of caregivers of people with brain health challenges (dementia, mental ill health, intellectual disability) experienced high levels of distress, burden, loneliness and social isolation. The COVID-19 pandemic has significantly increased these impacts, particularly since these caregivers are often older and physically vulnerable themselves. The aim of this cross-sectional study is to explore coping and caregiver burden, loneliness and social isolation in caregivers of people with brain health challenges during the COVID-19 pandemic. METHOD: CLIC-Caregiver was a cross-sectional, online, and global survey (June 2nd - November 15th , 2020) using self-administered questionnaires directed at informal caregivers of people with long-term brain health challenges. The study was embedded within a larger survey of loneliness and social isolation for general public ('Comparing Loneliness and Isolation in COVID-19' (CLIC)), including validated loneliness and isolation tools. Translated into ten different languages such as Arabic, French, Romanian, etc, the survey was disseminated over 100 countries. Respondents were included in the CLIC-caregiver sub-study if they answered yes to the question 'Do you provide care and support to a family member or friend with a long-term or life-limiting health problem or disability (including mental health)'. The CLIC project received the initial global ethical approval from Ulster University. The data were fully anonymized. RESULT: From the CLIC main study, 5243 (25%) identified themselves as caregivers. This proportion varied in different countries, from 12 % in Romania to 65% in France. 2323 (44%) had care recipients with dementia, 1761 with physical conditions (disability or long-term illness), 832 with enduring mental health problems, and 404 with intellectual disability. Measures of caregiver burden, loneliness and social isolation will be compared across geographic regions, sociodemographic factors, and risk factors for poor outcomes sought. Findings will be distributed to relevant stakeholders in the form of a project report, with region and country-specific outcomes. This will support recommendations and actions supporting caregivers of people with brain health challenges. CONCLUSION: This represents the largest, most widespread survey on the impact of the COVID-19 pandemic on caregivers of people with long-term conditions to date. It will be an important resource for support agencies and to inform policy.

- Background: Informal caregivers may experience high levels burden. Prior to COVID-19, loneliness and social isolation, and especially the discordance between them, were recognized for rapid aging-related cognitive decline. The COVID-19 has significantly increased social isolation and loneliness in caregivers. Thus, we aimed to explore the variables that were associated with higher care burden among all caregivers and only among caregivers for people living with dementia, and whether the increased burden could be associated with a discrepancy between loneliness and social isolation. Method: ‘Comparing Loneliness and Isolation in COVID-19’ was an online global survey of over 20,000 respondents, including 5243 caregivers across 50 countries with enduring brain or/and physical health conditions. We first used a multilevel modelling to identify risk factors associated with higher burden. Then, we defined profiles of discrepancy between loneliness and social isolation, based on the differences between standardized score on a scale of loneliness and of social connectedness and estimated the association between the discrepancy and higher burden. Result: In our sample, 74% of caregivers were female, 44% were caring for people with dementia, and 22% for people with multiple conditions, including dementia. The most prevalent age group was 60-69 years old. Factors significantly associated with higher care burden were being female, having poorer financial situation, worse mental health during the pandemic, caring for people with dementia or intellectual disabilities, caring in the same home, being diagnosed with COVID, and changes of care abilities. 40% of caregivers consistently reported high level of loneliness and social isolation, 38% reported consistent lower levels of both, and two groups reported discordance (low levels of loneliness and high social isolation in 13%; high levels of loneliness and mild social isolation in 12%). The latter group was at the highest risk of self-reported increased and intense care burden. Conclusion: This represents the largest, most widespread survey on the impact of the COVID-19 pandemic on caregivers of people with long-term conditions to date and reflects the importance of capturing the nuances in the relationship between loneliness and social isolation in caregivers. It will be an important resource for support agencies and to inform policy.
