A study published online today in Science, led by researchers from Boston Children’s Hospital and Harvard Medical School, used whole-genome sequencing of individual neurons and found strong evidence that brain mutations accumulate as we age. They also found that mutations accumulate at a higher rate in people with genetic premature aging disorders causing early brain degeneration. …read more
