Ventral tegmental area dopaminergic action in music therapy for post-traumatic stress disorder: A literature review

Meng Ning et al. Front Psychol. .

Abstract

Post-traumatic stress disorder (PTSD) is a debilitating sequela of extraordinary traumatic sufferings that threaten personal health and dramatically attenuate the patient's quality of life. Accumulating lines of evidence suggest that functional disorders in the ventral tegmental area (VTA) dopaminergic system contribute substantially to PTSD symptomatology. Notably, music therapy has been shown to greatly ameliorate PTSD symptoms. In this literature review, we focused on whether music improved PTSD symptoms, based on VTA dopaminergic action, including the effects of music on dopamine (DA)-related gene expression, the promotion of DA release and metabolism, and the activation of VTA functional activities. In addition, the strengths and limitations of the studies concerning the results of music therapy on PTSD are discussed. Collectively, music therapy is an effective approach for PTSD intervention, in which the VTA dopaminergic system may hold an important position.

Keywords: dopaminergic action; music therapy; post-traumatic stress disorder; symptom improvement; ventral tegmental area.

A simplified neural pathway for acoustic processes from the cochlea to the auditory cortex. The auditory cortex sends projections to the amygdala and then to the ventral tegmental area (VTA) (Koelsch, 2014). Inset, the DA level is transiently elevated after trauma, followed by persistent hypodopaminergia (Corralfrias et al., 2013). Music activates the VTA function and stimulates the DA release, which may reduce PTSD-induced hypodopaminergia in the brain, which ameliorates PTSD symptoms.
