Detecting subtle but clinically significant cognitive change in an ageing population


Faculty of Biology, Medicine and Health

About the Project

A major challenge facing dementia research is identifying the earliest indicators of clinically-significant cognitive decline. This research project will be linked to the newly established Memory Assessment & Cognitive Ageing Research Unit (MACARU), led by the primary supervisor. This provides the opportunity to follow the cognitive and other functional changes in a large sample of older adults over time. Performance will be linked to key lifestyle and health indicators to explore potential at-risk subgroups. While it is clearly established that cognition and memory decline with age, it remains unclear which patterns of deterioration are indicative of a dementia trajectory, and which are not. The project will therefore investigate this and seek to establish early markers of clinically significant functional decline in healthy older adults by combining measures of memory and cognition, eye tracking, and brain function and integrity. Our highly sensitive methods of memory/cognitive assessment will be optimized for an older population and for online use either from the participant’s own home or from clinical centres. We have pioneered the use of eye-tracking methodology in memory research, establishing that pupil response and eye gaze metrics reflect subtle differences in memory performance in healthy adults. Therefore, one future focus of this research will be to explore this as a potential neurocognitive marker of clinically-significant memory decline. Our third major focus is on neuroimaging and its use in understanding memory function and dysfunction. With our MR-compatible eye-tracker, we will combine pupil and eye movement, brain function and integrity and cognition and memory indices in subgroups of our ageing cohort. Identifying biomarkers of very early dementia, characterizing at-risk groups, and exploring the complexity of declines memory and cognition in an ageing population will have significant impact for older people with and without dementia, for research into prevention and treatment, and for future policy-making.

Candidates are expected to hold (or be about to obtain) a minimum upper second class honours degree (or equivalent) in a related area / subject. Candidates with experience in neuroscience, psychology, digital programming, or MR imaging and with an interest in the ageing brain are encouraged to apply.
