"Uncovering Ancient DNA's Link to Modern Alzheimer's and MS Rates"

Researchers have analyzed ancient human DNA to create a gene bank, revealing insights into the historical spread of genes and diseases. They found that genes increasing the risk of diseases like Alzheimer’s originated from hunter-gatherers, and linked the spread of multiple sclerosis (MS) genes to ancient migrations. The study explains modern health phenomena like the North-South MS prevalence gradient and could revolutionize the treatment of neurodegenerative diseases. The findings provide new understanding of the genetic and migratory history affecting modern disease prevalence, particularly in northern versus southern Europe.
