Studies also linked BDNF polymorphisms with changes in brainstem auditory-evoked response test results. Furthermore, BDNF levels are reduced in tinnitus, psychiatric disorders, depression, dysthymic disorder that may be associated with stress, conversion disorder, and suicide attempts due to crises of life. For this purpose, we investigated whether there is any role of BDNF changes in the pathophysiology of tinnitus %K BDNF gene polymorphism %K neurotrophic factor %K serum BDNF level %K tinnitus %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5501024/
