At-home blood test and brain testing could screen people for dementia risk

A finger prick blood test combined with online brain testing—all done from home—could one day effectively identify people's risk of developing dementia, according to a new study.

Led by the University of Exeter and published in Nature Communications, the study found that the level of proteins linked to dementia which were measured in the postal blood test were linked to performance on a series of brain tests. The research paper is titled “Alzheimer’s Disease blood biomarkers measured through remote capillary sampling correlate with cognition in older adults.”

The research concludes that at-home testing could be a way to identify people at highest risk of dementia, who could then be prioritized for further testing, treatment and support. It could also identify people at low risk who could be given assurance, as well as those with moderate risk who may benefit from monitoring and guidance on reducing their risk in future.
