Study results from the Imperial College, London, UK and Spain, published in the Proceedings of the National Academy of Sciences, showed if stroke patients listen to music they like, they experience an improvement in visual awareness. Visual neglect, a visual impairment related to one side of the body, is experienced by 60% of stroke patients and is the result of injury to the right side of the brain. During the study, 3 stroke patients who had lost awareness of half of their field of vision had to complete tasks under three conditions: while listening to music they preferred; while listening to music they did not like; and in silence. All three of the stroke patients were able to identify colored shapes and red lights in their depleted side of vision much more accurately while they were listening to their preferred music, as compared with the other two conditions.
