NEAR dissertation, 4 December 2020: Johan Skoog
The NEAR researcher Johan Skoog, University of Gothenburg, defended his thesis with the title: “Sleep and cognition in old age: Birth cohort differences, dementia, and biomarkers of Alzheimer’s disease”.
The main findings from the thesis imply that 70-year old’s of today have better sleep quality, in terms of insomnia, than 70-year old’s 30 years ago (Do later-born birth cohorts of septuagenarians sleep better? Oxford Academic ). Different types of sleep problems may play varying roles during the life course concerning dementia risk; insomnia could potentially be more important in midlife while waking up too early (terminal insomnia) or long sleep duration (>9 hours) may be more critical later in life (Sleep disturbances and dementia risk: A multicenter study – ScienceDirect). This study included the NEAR databases: H70 and Kungsholmen Project, as well as the Cardiovascular Risk Factors, Aging and Dementia (CAIDE) study, which includes participants from Finland. Finally, sleep may play an important role in the early processes of Alzheimer’s Disease (AD) by potentially decreasing clearance or increasing production of amyloid β that is a biological marker for AD.
