TRAUMATIC EVENTS AND MENTAL DISEASES: THE ROLE OF CERTAIN NEUROTRANSMITTERS, METALLOENZYMES AND HORMONES

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. All articles were reviewed, including original studies, systematic reviews and meta-analyses. CONCLUSION: Conclusions: Unfortunately, the imbalance of neurotransmitter systems of the brain remains not fully understood under such a condition at this stage of world science development. Their role remains unclear both during the immediate exposure to the stress factor and in the remote period. Therefore, under¬standing the mechanisms underlying the systemic consequences of PTSD is crucial for the development of prediction models and timely rational therapy.

WHEN QUARTAN FEVER RELIEVED DEPRESSION: THE INCEPTION OF PYRETOTHERAPY IN THE GRECO-ROMAN ANTIQUITY.

OBJECTIVE: The aim: This paper explores the documentation of the effect of quartan fever on, the ancient Greek equivalent of conditions falling nowadays under the spectrum of depression, in Greco-Roman medical sources. PATIENTS AND METHODS: Materials and methods: The authors searched original medical texts written in Greek by physicians who lived and practiced Medicine in the broader Mediterranean region from the 5th century BC to the 7th century AD for records related to quartan fever and neuropsychiatric diseases. CONCLUSION: Conclusions: Quartan fever was used as a treatment for neuropsychiatric conditions until the middle of the 20th century. Although malaria can have severe neuropsychiatric sequelae, the neuroimmunological underpinnings of the effect of fever and heat on depression warrant further investigation.
