Holocaust trauma may affect descendants' genes

Descendants of Holocaust survivors show genetic differences that may affect stress response and social bonding.

Why it matters

  • Trauma from the Holocaust may have epigenetic effects on descendants.
  • Understanding these effects can help in developing interventions for trauma-related issues.

By the numbers

  • 371 participants, including 186 descendants of Holocaust survivors.
  • Descendants showed lower attachment avoidance and changes in genes related to stress and social bonding.

The big picture

  • Trauma can have long-lasting effects that span generations.
  • Epigenetic changes might help descendants cope with stress and form stronger social bonds.

What they're saying

  • Some readers are becoming less skeptical about generational trauma.
  • Personal experiences highlight the lasting impact of trauma.
  • Questions about the control group and specificity to Ashkenazi Jews.

Caveats

  • The study doesn't claim to have found a definitive mechanism for generational trauma.
  • The findings may be specific to certain populations.

What’s next

  • More research is needed to understand the mechanisms and implications of these findings.
