Can epigenetic biomarkers lead us to precision medicine in predicting treatment response and remission for patients being considered for ECT?

While electroconvulsive therapy (ECT) is the gold standard for the treatment of depression, there is currently a lack of clinically useful biomarkers predictive of treatment response. Epigenetics provides reasonable potential as a biomarker for treatment response for ECT, given that the study of epigenetics combines both the impact of biology and environment in the shaping of psychopathology. Initial limited studies are promising. Further studies to establish precision medicine in term of ECT treatment response using epigenetics predictors can provide great benefit to both patients and physicians in saving time, money, and frustration.
