The body always remembers. Like other children of Vietnamese war refugees, I understand how hardships and inconceivable loss leave marks. Psychologists in the 1990s found roughly half of Holocaust survivors were still suffering from post-traumatic stress disorder (Dialogues in Clinical Neuroscience). Emerging studies show that, in communities of survivors, trauma may also be passed onto subsequent generations through epigenetic changes, where the mechanism by which our body reads DNA – not DNA itself – is altered (Stanford University). This intergenerational transfer can also be behavioral; parents with severe anxiety may model detrimental patterns of thinking and feeling.
