This article doesn’t really mention mental illness except for schizophrenia, as a side note. I really do think, however, that we’ll find that this area of study, epigenomics, will help explain many mental illness (esp. bipolar) better than standard DNA-based genomics. Best part? It might be easier to design treatments that work with epigenomes than it currently is with regular old genes.
