Were there long term consequences on Irish mental health because of the Great Hunger? Epigenetics is the study of changes in gene expression that do not involve alterations to the genetic code or DNA, but whose effects may persist over several generations. Since 2013, Dr. Oonagh Walsh has been researching and reporting on the negative effects maternal starvation had on babies during and immediately after the Great Hunger, resulting in possible epigenetic changes. Similar studies have been carried out on other traumatized populations, like Native Americans and survivors of the Dutch Hunger Winter of ‘44-45. Walsh’s findings have uncovered high rates of mental illnesses and a subsequent increase in psychiatric asylum commitment among the population and their descendants. Join us for this fascinating look at the long term effects of trauma.
