According to background in a recent report, apathy (lack of interest or indifference) may hasten cognitive decline among people with dementia.

STUDY: The actions of 40 residents with dementia in a nursing home were tracked using video. Three videos of each resident (while dining, while interacting with a staff member and a random selection) were analyzed. Five factors were evaluated: environmental stimulation, ambiance, crowding, staff familiarity and light and sounds.
