Objective: Aim: To study the role of certain neurotransmitters (brain-derived neurotrophic factor (BDNF), 5-hydroxytryptamine (5-HT)), metalloenzymes (matrix met-alloproteinase-9) (MMP-9) and hormones (ghrelin) in the pathogenesis of mental disorders associated with stress under the impact of traumatic events.
Patients And Methods: Materials and methods: We conducted a systematic search of major electronic medical databases published before October 1, 2022. Such keywords as (post-traumatic stress disorder OR PTSD), (Brain-derived neurotrophic factor OR BDNF), (matrix metalloproteinase-9 OR MMP-9), (serotonin OR 5-HT), ghrelin, melatonin identified relevant studies.
