The Efficiency of Binaural Beats on Anxiety and Depression—A Systematic Review

Anxiety and depression are two of the most impactful diseases on quality of life and cause significant disability to patients. It burdens the medical system even as a stand-alone pathology or a secondary condition. These conditions can occur secondarily after a patient suffers from other illnesses, such as upper motor neuron lesions. Binaural beats are a new and emerging type of technology that can be used as an adjunct therapy for anxiety and depression as well as in neurologic conditions to some extent. We searched through the MEDLINE, PsychINFO, EMBASE, CENTRAL, ISRCTN, and ICTRP databases to identify studies using binaural beats as therapy for anxiety and depression. Twelve articles were declared eligible to be included in this review. Binaural beats, whether used in the form of pure beats or masked by another sound, have shown better results in alleviating symptoms of anxiety and depression compared to control conditions such as no music or the use of noise-canceling headphones alone. The results suggest that using binaural beats could be a promising and easy-to-use method to help alleviate the symptoms of anxiety and depression.
