Boosting Cognition With Music in Patients With Disorders of Consciousness.

Background. Music listening conveys beneficial effects on cognitive processes in both normal and pathologic cerebral functioning. Surprisingly, no quantitative study has evaluated the potential effects of music on cognition and consciousness in patients with disorders of consciousness. Objective. The aim of the present study was to evaluate the effect of music on cerebral processing in patients with disorders of consciousness. Methods.
