Sleep and cognition in older adults: Does depression matter? An actigraphy and polysomnography study

Authors: Alix Mellor, Flavie Waters, Helen McGowan, Jennifer Maul, Katherine A. Sanders, Romola S. Bucks

Journal: Archives of Psychology

Volume & Issue: 2 & 1

The impact of sleep on cognition is well recognised, although research in older adults is lacking, as are investigations into how depression might impact on this relationship. This study assessed the relationship between sleep (assessed with actigraphy and polysomnography) and cognitive performance in older adults (50–78 years) with (n = 10) and without (n = […]

Longitudinal cognitive decline in the AIBL cohort: The role of APOE ε4 status.

The ε4 polymorphism of the APOE gene confers a substantially increased risk of developing Alzheimer’s disease. However, the influence of the ε4 allele on age-related cognitive functioning is more contentious. Previously, we demonstrated relatively little evidence for a role of the ε4 allele on baseline cognitive performance in older adults in the Australian Imaging, Biomarkers […]

An analysis of systems of classifying mild cognitive impairment in older people.

Authors: Collie A, Maruff P

Journal: The Australian and New Zealand Journal of Psychiatry

Volume & Issue: 36 & 1

Page No.: 133-40

Year Published: 2002

OBJECTIVE: Over the past two decades, a number of systems have been developed for the classification of cognitive and behavioural abnormalities in older people, in order that individuals at high risk of developing neurodegenerative disease, particularly Alzheimer’s disease, may be identified well before the disease manifests clinically. This article critically examines the inclusion and exclusion […]

Statistical and conceptual issues in defining post-operative cognitive dysfunction.

Authors: Lewis M, Maruff P, Silbert B

Journal: Neuroscience and Biobehavioral Reviews

Volume & Issue: 28 & 4

Page No.: 433-40

Year Published: 2004

The occurrence of post-operative cognitive dysfunction is a distressing complication following surgery. In an effort to gain a more complete understanding of patients’ cognitive recovery following surgical procedures common neuropsychological assessment tools have been adopted in a repeated measures design. It is widely regarded that this represents the most comprehensive method of determining cognitive status […]

Lack of reliable evidence for a distinctive ε4-related cognitive phenotype that is independent from clinical diagnostic status: findings from the Australian Imaging, Biomarkers and Lifestyle Study.

Individuals who carry the apolipoprotein E ε4 polymorphism have an increased risk of late-onset Alzheimer’s disease. However, because possession of the ε4 allele confers an increased risk for the diagnosis of dementia, it has proven problematic in older individuals to dissociate the influence of ε4 on cognitive capacity per se as distinct from its influence […]
