Musical anhedonia

Common card · No. 348376

Musical anhedonia (or specific musical anhedonia) is a neurological phenomenon characterized by a lack of sensitivity to reward from or pleasurable responses to music. People with this experience, unlike those suffering from amusia, have no deficiencies in their perception of music, but fail to derive pleasure from music listening while maintaining normal hedonic response to non-musical stimuli. Musical anhedonia has been found to be both acquired, occurring as a result of brain damage, and present in the absence of any neurological damage. Research has shown that people with this condition have reduced functional connectivity between the cortical regions responsible for processing sound and the subcortical regions related to reward. Musical anhedonia without brain damage has been estimated from studies to be present in 5-10% of the general population while acquired musical anhedonia resulting from focal brain damage likely much rarer in occurrence.
