The study revealed that people with a type of dementia called semantic dementia were unable to identify the melodies or titles of famous tunes. They were also unable to differentiate between sounds such as laughing and coughing.

MRIs of the brain of participants showed that a particular region in the brain located behind the right ear, called the right anterior temporal lobe, had shrunk in patients with semantic dementia. This was not the case in the brain of normal individuals as well as those with Alzheimer's.
