Project Snapshot

Cognitive ageing is the process of change in cognitive function that occurs as an individual ages. Reported to typically involve decline in fluid intelligence factors, such as processing speed, executive function and episodic memory, and retention of crystallised intelligence factors, such as knowledge-based numeric and verbal abilities. Estimates of the timing and extent of these changes vary between studies. This may be due to methodological differences, or failure to account for the influence of occult pathology or genetic factors. The aim of this series of studies is to understand the nature and magnitude of age related cognitive decline and the impact of occult pathology and genetics on trajectories of normal cognitive ageing.
