Researchers have discovered changes in blood samples associated with Alzheimer’s disease. A new international study examined disease-discordant twin pairs: one sibling who suffered from Alzheimer’s disease and one who was cognitively healthy. The researchers used the latest genome-wide methods to find out whether the twins’ blood samples had any disease-related differences in epigenetic marks, which are sensitive to changes in environmental and lifestyle factors. Differences in epigenetic marks between the sibling who suffered from Alzheimer’s disease and the healthy sibling were discovered in multiple genomic regions.
