Non-Invasive Neurofeedback Training to Alleviate Tinnitus Distress

Intervention via neurofeedback has shown promising results for many neurological disorders including schizophrenia, post-traumatic stress disorder, ADHD, anxiety and major depressive disorder, with benefits lasting over several weeks after the completion of training ; neurofeedback-guided training has led to participants successfully alter activity in brain regions that mediate emotional response, mood and cognitive control. Because these brain regions and functions are also implicated in bothersome tinnitus, real-time neurofeedback training based on ongoing activity in these targets can potentially improve the psychological distress associated with tinnitus severity. Real-time neurofeedback can provide a valuable training tool for coping with tinnitus-related distress and help underpin the development of intervention-based treatments.
