AIBL is a study of over 2,000 people assessed over a long period of time (over 10 years) to determine which biomarkers, cognitive characteristics, and health and lifestyle factors determine subsequent development of symptomatic Alzheimer’s Disease (AD).

The baseline inception cohort consisted of:
i. 211 individuals with AD as defined by NINCDS-ADRDA (McKhann et al, 1984);
ii. 133 individuals with Mild Cognitive Impairment (MCI)
iii. 768 healthy individuals without cognitive impairment. This group included volunteers with at least one copy of the ApoE ?4 allele, volunteers without a copy of the ApoE ?4 allele and 396 volunteers who expressed subjective concern about their memory function.

The enrichment cohort consists of:
i. 142 individuals with AD
ii. 220 individuals with MCI
iii. 582 individuals with without cognitive impairment.

The data was collected through clinics and questionnaires.
