Recent investigations highlight apathy as a separate entity from depression ( Marin, Fogel, Hawkins, Duffy, & Krupp, 1995 ; Starkstein, Petracca, Chemerinski, & Kremer, 2001 ), which has been uniquely associated with cognitive and functional decline in neurologic diseases ( Camargo, Serpa, Jobbins, Berbetz, & Sabatini, 2018 ; Palmer et al, 2010 ; Vicini Chilovi et al, 2009 ).
