In a new study, researchers at the Swedish medical university Karolinska Institutet have identified epigenetic changes - known as DNA methylation - in the blood of patients with schizophrenia. The researchers were also able to detect differences depending on how old the patients were when they developed the disease and whether they had been treated with various drugs. In the future this new knowledge may be used to develop a simple test to diagnose patients with schizophrenia.
