Potential future diagnostic categories: classification of amusia aetiologies in 301 patients. This figure is simply a record of the aetiologies identified in studies which were not suitable for analysis or synthesis but nonetheless contained amusic patients. Speculatively, some of these aetiological categories might be important when a full systematic review is possible in the future.
