Depression: Researchers develop blood test for depression,bipolar disorder

Researchers at Indiana University of America have achieved a new blood test capable of detecting depression and mood disorders, which helps diagnose the disease and thus start the treatment journey at a stage early.


And according to what was posted on the Medical Express website, researchers have successfully activated a new test that detects blood biomarkers that monitor PTSD and Alzheimer’s disease.

The study confirmed that the test is based on examining vital signs of RNA, which can characterize the severity of the patient’s depression, the extent to which he may be at risk for major depression in the future. and the risk of developing bipolar disorder. in the future known as manic-depressive illness.

The study team confirmed that the experiments that were carried out to develop the blood test were carried out over a four-year period on a number of participants, after the researchers followed a rigorous four-step approach to the test. discovery, prioritization, validation and testing, where the participants’ high and low mood states were monitored, from 26 biomarkers among clinically sensitive people with depression or mania, determining their power to predict who will be ill and who will fall ill in the future.
The study confirmed that mood disorders are caused by genes specific to the body clock and also by genes that regulate seasonal cycles, nighttime, sleep and wakefulness, which explains the worsening of the patient’s condition during seasonal changes and sleep changes that occur in mood disorders. , after statistics have confirmed that 1 in 4 people who suffer from a depressive episode during their lifetime.
