Sydney Older Persons Study: Wave 5, 2000 - 2003

The Sydney Older Persons Study is a longitudinal study aiming to increase the understanding about ageing successfully, with a focus on the definition, consequences and possible causes of neurodegenerative disorders. Over a 10 year period, participants aged 75 years and older were regularly tested on their mental and physical function. Over the span of the study, the average age was 89 years old, including 15 participants who were over 100 years old. The fifth and final wave of the study involved the subgroup of participants from Wave 4 who underwent an MRI scan and further neuropsychological assessment. These same participants underwent another MRI scan, more detailed neuropsychological assessment and a complete medical review. The spouses, family members or friends who were interviewed in the earlier waves were also re-interviewed in order to measure the presence of any health changes and their impact over time. Background variables include age, gender, country of birth, parents' country of birth, marital status and main language spoken.
