The UK Biobank is the worlds largest and most detailed collection of biomedical information collected from 500,000 survey participants. Participants were aged 40-69 years when they initially submitted their demographic, lifestyle, and health information along with samples of their blood, urine and saliva. Their anonymized information and samples are made available for research into why some develop a condition while others do not.
One of studies which is getting underway is looking to examine the cognitive functions of the 500,000 participants. Participants will be able to log in and take a series of cognitive tests. These tests are a repeat of tests they completed when they enrolled in the Biobank's program, allowing the researchers to compare results and look for risk factors which may lead some of the participants to develop Alzheimer's or another dementia.
