A recent study in the UK says that listening to pleasant music may help to restore vision that has been impaired in stroke patients.

According to the BBC, up to 60 per cent of people who had a stroke develop a condition called "visual neglect." Visual neglect, or impaired visual awareness, is a condition in which sufferers can no longer track objects in the visual field controlled by the brain half where the stroke occurred. Our optic nerves are crossed. That means that when a person has a stroke in the right hemisphere of the brain, impaired visual awareness will occur in the left eye. The condition is caused by damage to brain areas that are responsible for integrating vision, attention and action and not by the areas of the brain that are responsible for vision proper. In extreme cases, people who have the condition complete ignore an area of their field of vision. They may, for example, only shave half of their face or eat only the food on one side of their plate. A study published in the Proceedings of the National Academy of Sciences (PNAS) suggests that listening to pleasant music can help to ease the problem. The study looked at three patients who has lost half their field of vision. They were asked to perform some tasks in silence, while listening to music they didn't like and while listening to music they did like. All patients were much more accurate when listening to pleasant music. The influence of the music wasn't negligible either. One patient, for example, could only point out light in 15% of the cases when no sound or unpleasant music was present. This went up to 65% of cases when listening to pleasant music. Readers should take into account, however, that this study lacks all credibility of a properly conducted study. Even if real, these effects could be the result of random chance. In three patients, the probability of random luck is far from negligible. There was no control group. It seems obvious, that the same type of effect would happen in people with normal vision. I think that virtually all of us perform less well when working while someone is jackhammering the pavement, or while music we do not like is being played, and that the majority of us perform better while hearing music we do like. Also, while certainly not lacking interest, even if the effect turns out to be real, it is a very limited aspect of the complex spectrum of problems stroke patients experience. Listening to pleasant music will not solve the vast majority of problems, no matter how much we'd like it to.
