BDNF and Tinnitus: Here, for example, the absence of hereditary contributors to enhanced distress, which have been shown to increase susceptibility to tinnitus (Amanat et al. 2020; Lopez-Escamez and Amanat 2020; Ruan et al. 2018; Szczepek et al. 2019), including the BDNF Val 66 Met polymorphism (Vanneste et al. 2021), have to be regarded in the context of a possible contribution to tinnitus resilience and long-term habituation.
