Many psychiatric diseases are consistent with the theory of epigenetic dysregulation because of their fluctuating nature and disease course. Single gene and whole genome epigenetic analyses have shown atypical epigenetic markers in the blood and brain of individuals with psychiatric diseases including abnormalities in DNA methylation, histone modifications and microRNA expression.
