FTD = frontotemporal dementia; AD = Alzheimer’s disease; SD = standard deviation; adj = adjusted; SE = standard error; F = female; M = male; CDR = Clinical Dementia Rating Scale.

^aCorrected for patient age.

^bFor controls, the “patient” was the member of the couple who participated in the larger study being conducted through the UCSF MAC and UC Berkeley, as a patient analog; the “caregiver” was the member of the couple who participated in a subset of study tasks, as a caregiver analog. Unless otherwise noted, analyses reporting on “patients” include control patient analogs and analyses reporting on “caregivers” include control caregiver analogs.

^cControl couples > AD couples

^ePatients > caregivers
