Depression is now a very common disorder, with around one in every four people being affected. There is a lack of an objective measure, such as a blood test for the diagnosis of depression, and the treatment approaches largely follow a trial-and-error approach, thus lacking a definite path. Breakthrough research has overcome this loophole. Researchers at the Indiana University School of Medicine have developed a blood test using a precision medicine approach to treat depression and bipolar disorders.

The study published in the journal Molecular Psychiatry has leveraged the biological basis of mood disorders to design a potentially promising blood test. The study is a sequel to a previous study that identified blood biomarkers associated with suicidality, pain, post-traumatic stress disorder, and Alzheimer’s disease. The blood test is based on the ability of RNA biomarkers to decipher…
