Shorter telomeres on the ends of white blood cell chromosomes may signal a heightened dementia risk, suggest the results of a large long term study, published online in the journal General Psychiatry. They are associated with smaller total and white matter brain volume, which helps the body process information, and may be a predictor of future brain health, say the researchers. A telomere–the equivalent of a shoelace cap—is intended to prevent the loss of coded DNA by a chromosome fraying or unravelling when it replicates.
