Can Molecular Biology Propose Reliable Biomarkers for Diagnosing Major Depression?

Background: Modern medicine has provided considerable knowledge of the pathophysiology of mental disorders at the body, systemic, organ and neurochemical levels of the biological organization of the body. Modern clinical diagnostics of depression have some problems, that is why psychiatric society makes use of diagnostics and taxonomy of different types of depression by implemention of modern molecular biomarkers in diagnostic procedures. But up to now, there are no reliable biomarkers of major depressive disorder (MDD) and other types of depression.

[The current state and future prospects of depression research (clinical and classification problems)].

Despite decades of research, neurobiological studies of depression haven't achieved significant results. Many experts propose that one of the main reasons for this failure is current diagnostic standards not considering the heterogeneity and polymorphism of depression. Research is unable to identify specific neurobiological changes due to formal diagnosis 'major depressive disorder' and new diagnostic criteria are needed.
