Researchers at the RIKEN Center for Brain Science in Japan have studied mice, post-mortem human brains, and schizophrenia patients and discovered that a particular form of the mental health disease has a visible DNA-modifying reaction. Certain markers that help diagnose other disorders are diminished in schizophrenia, making it more difficult to identify and treat. Developing schizophrenia is related to genetics and environmental factors combined, so looking for any changes in genetic structure has allowed these researchers to potentially find a new marker. The subtype in question results in “sulfide stress” and primes sulfide production which can be detected in hair. Not only will this finding help to accurately diagnose schizophrenia, but it can also provide a new paradigm for designing drugs for treatment.
