Hemodynamic and structural brain measures in high and low sedentary older adults
(2021)Due to its cardiovascular effects sedentary behaviour might impact cerebrovascular function in the long term, affecting cerebrovascular regulatory mechanisms and perfusion levels. Consequently this could underly potential ... -
Transitions in frailty phenotype states and components over 8 years: evidence from The Irish Longitudinal Study on Ageing
(2021)Aim: Fried's frailty phenotype (FP) is defined by exhaustion (EX), unexplained weight loss (WL), weakness (WK), slowness (SL) and low physical activity (LA). Three or more components define the frail state, and one or two ... -
Prevalence of Sarcopenia and Associated Factors in Older Adults Attending a Day Hospital Service in Ireland
(2021)Purpose: Sarcopenia is a muscle disease that is linked to the effects of ageing, chronic diseases, physical inactivity, and poor nutrition. In Ireland, there is a lack of readily available information on sarcopenia in older ... -
Associations between cognitive function, actigraphy-based and self-reported sleep in older community-dwelling adults: Findings from the Irish Longitudinal Study on Ageing
(Wiley, 2020)Objective: Cognitive impairment is prevalent in older ages. Associations with sleep are well established; however, ambiguity remains in which sleep characteristics contribute to this impairment. We examined cross-sectional ... -
Discrepancies in self-reported and actigraphy-based sleep duration are associated with self-reported insomnia symptoms in community-dwelling older adults
(2021)Objectives: To establish agreement between self-reported and actigraphy-based total sleep time (TST). To determine the impact of self-reported sleep problems on these measurements. Design: Cross-sectional study using data ... -
Objective Sleep Duration in Older Adults: Results From The Irish Longitudinal Study on Ageing
(Wiley, 2020)Objective: This study assessed the distribution and correlates of objective sleep duration in the older population in Ireland. Design: Cross-sectional study using population-derived data from wave 3 of The Irish Longitudinal ... -
Altered lives in a time of crisis: The impact of the COVID-19 pandemic on the lives of older adults in Ireland. Findings from The Irish Longitudinal Study on Ageing
(TILDA, 2021)The ongoing pandemic of SARS-CoV-2, a novel coronavirus that causes COVID-19 infection and disease, is threatening healthcare systems globally as well as in Ireland. (1) The COVID-19 pandemic, and public health-associated ... -
Perceived stress before and during the COVID-19 pandemic
(2020)Since the beginning of the COVID-19 pandemic, perceived stress has increased significantly among older adults. This increase will likely negatively affect both physical and psychological wellbeing among this population. ... -
Older adults' experience of ageism during the COVID-19 pandemic
(TILDA, 2020)Despite the fact that the vast majority of older adults are not physically, cognitively or mentally impaired, age-related stereotypes persist. These stereotypes commonly portray older adults as physically and cognitively ... -
Preparing for COVID-19 vaccination: important learnings from the Irish Longitudinal Study on Ageing (TILDA)
(TILDA, 2020)This report brings together important information on vaccinations among adults aged 60 years and older learned from the Irish Longitudinal Study on Ageing (TILDA), which can inform the rollout of COVID-19 vaccinations. The ... -
Older adults shielding at home
(TILDA, 2020)Two thirds of adults aged 60 and older agreed or strongly agreed with shielding. Interestingly, a higher percentage of those most affected by policy, the over 70s, agreed with it. Whether people lived alone or with others ... -
New self-reported exhaustion during the COVID-19 Pandemic
(2021)In 2020, participants from The Irish Longitudinal Study on Ageing were surveyed to provide vital and timely information on lived experiences of older adults during the SARS-CoV-2 pandemic. During 2020, older adults experienced ... -
Physical and Mental Health of Older People while Cocooning during the COVID-19 Pandemic
(2021)Background: Cocooning or shielding, i.e. staying at home and reducing face-to-face interaction with other people, was an important part of the response to the COVID-19 pandemic for older people. However, concerns exist ... -
Age-related normative changes in cerebral perfusion: data from The Irish Longitudinal Study on Ageing (TILDA)
(2021)Objective: To establish normative reference values for total grey matter cerebral blood flow (CBFGM) measured using pseudo-continuous arterial spin labelling (pCASL) MRI in a large cohort of community-dwelling adults aged ... -
Functional Analysis of Continuous, High-Resolution Measures in Ageing Research: A Demonstration using Cerebral Oxygenation Data from The Irish Longitudinal Study on Ageing
(2020)Background: A shift towards the dynamic measurement of physiologic resilience and improved technology incorporated into experimental paradigms in aging research is producing high-resolution data. Identifying ... -
Impaired orthostatic heart rate recovery is associated with smaller thalamic volume: Results from The Irish Longitudinal Study on Aging (TILDA)
(Wiley, 2020)The thalamus is a central hub of the autonomic network and thalamic volume has been associated with high‐risk phenotypes for sudden cardiac death. Heart rate response to physiological stressors (e.g., standing) and the ... -
Grey matter volume in the right Angular Gyrus is associated with differential patterns of multisensory integration with ageing
(Elsevier BV, 2020)Multisensory perception might provide an important marker of brain function in ageing. However, the cortical structures supporting multisensory perception in ageing are poorly understood. In this study, we compared regional ... -
One-dimensional statistical parametric mapping identifies impaired orthostatic cerebrovascular and cardiovascular response in frailty index
(2020)Background: Orthostasis is a potent physiological stressor which adapts with age. The age-related accumulation of health deficits in multiple physiological systems may impair the physiological response to orthostasis ... -
Associations between neurocardiovascular signal entropy and physical frailty
(2021)In this cross-sectional study, the relationship between noninvasively measured neurocardiovascular signal entropy and physical frailty was explored in a sample of community-dwelling older adults from The Irish Longitudinal ... -
Protocol for a randomised controlled trial of a primary care intervention to Reverse Frailty and Enhance Resilience through Exercise and dietary protein Education (REFEREE) in community-dwelling adults aged 65 and over
(2020)Introduction: Resistance exercises and dietary protein have been shown to reverse frailty, yet they are not commonly offered in clinical practice. We aim to measure changes in health outcomes, including physical frailty ...
