The objective of this paper is to summarise the current Accepted 3 May 2016 knowledge of biomarkers for anxiety disorders, obsessive-compulsive disorder (OCD) and post- traumatic stress disorder (PTSD). Methods: Findings in biomarker research were reviewed by a task force of international experts KEYWORDS Anxiety disorders; in the field, consisting of members of the World Federation of Societies for Biological Psychiatry neuroimaging; genetic; Task Force on Biological Markers and of the European College of Neuropsychopharmacology neurochemistry; Anxiety Disorders Research Network. neurobiology; review Results: The present article (Part II) summarises findings on potential biomarkers in neurochem- istry (neurotransmitters such as serotonin, norepinephrine, dopamine or GABA, neuropeptides such as cholecystokinin, neurokinins, atrial natriuretic peptide, or oxytocin, the HPA axis, neuro- trophic factors such as NGF and BDNF, immunology and CO2 hypersensitivity), neurophysiology (EEG, heart rate variability) and neurocognition. The accompanying paper (Part I) focuses on neu- roimaging and genetics. Conclusions: Although at present, none of the putative biomarkers is sufficient and specific as a Downloaded by [Georg-August-Universitaet Goettingen], [Borwin Bandelow] at 05:52 18 July 2016 diagnostic tool, an abundance of high quality research has accumulated that should improve our understanding of the neurobiological causes of anxiety disorders, OCD and PTSD.
