Dementia is a thief that picks many pockets. In some guises, it takes our memories. Other forms rob us of inhibition. Sometimes it even takes away happiness itself.
A new study has shown for the first time how some forms of early-onset dementia are associated with a profound loss of pleasure linked to a wasting of 'hedonic hotspots' - brain regions associated with reward seeking.
