Associations between cognitive function, actigraphy-based and self-reported sleep in older community-dwelling adults: Findings from the Irish Longitudinal Study on Ageing
Scarlett, Siobhan; Kenny, Rose Anne; O'Connell, Matthew DL; Nolan, Hugh N; De Looze, Céline (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 ... -

Hennelly, Niamh; Ward, Mark; Scarlett, Siobhan; Hever, Ann; O'Connnor, Deirdre; McGarrigle, Christine; Kenny, Rose Anne (TILDA, 2023) -
Discrepancies in self-reported and actigraphy-based sleep duration are associated with self-reported insomnia symptoms in community-dwelling older adults
Scarlett, Siobhan; Kenny, Rose; Nolan, Hugh N; O'Connell, Matthew DL (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 ... -
Hemodynamic and structural brain measures in high and low sedentary older adults
Scarlett, Siobhan; Knight, Silvin; Kenny, Rose; Newman, Louise; Feeney, Joanne (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 ... -
Hospitalisation and surgery: Are there hidden cognitive consequences? Evidence from The Irish Longitudinal study on Ageing (TILDA)
Kenny, Rose; Scarlett, Siobhan (2018)Background: the dramatic shift in the global population demographic has led to increasing numbers of older people undergoing hospitalisation and surgical procedures.Objectives:to determine whether hospitalisation or ... -
Is phenotypical prefrailty all the same? A longitudinal investigation of two prefrailty subtypes in TILDA
O'Halloran, Aisling; Scarlett, Siobhan; Kenny, Rose; Romero-Ortuno, Roman (2019)Background: Fried's frailty phenotype is defined by five criteria: exhaustion, unexplained weight loss, weakness, slowness and low physical activity. Prefrailty (PF) meets one or two criteria. PF is of interest as a target ... -
Objective Sleep Duration in Older Adults: Results From The Irish Longitudinal Study on Ageing
Scarlett, Siobhan; Kenny, Rose; Nolan, Hugh; O'Connell, Matthew DL (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 ... -
Variability and agreement of frailty measures and risk of falls, hospital admissions and mortality in TILDA
Kenny, Rose; O'Halloran, Aisling; Scarlett, Siobhan (2022)Little is known about the within-person variability of different frailty instruments, their agreement over time, and whether use of repeat assessments could improve the strength of associations with adverse health outcomes. ...
