Huntington’s Disease Effects Detected in First Two Weeks of Embryonic Development

Huntington’s disease, a fatal condition involving the death of brain cells, typically strikes people in midlife. But new findings suggest the disease process starts decades earlier. Although symptoms emerge in adulthood, researchers have been able to detect the earliest effects of Huntington’s in the first two weeks of human embryonic development. The findings recast Huntington’s as a developmental disease and point to new approaches for finding treatments.
