title: Spared emotional perception in patients with Alzheimer's disease is associated with negative caregiver outcomes.
abstract: Caregivers (CGs) for patients with Alzheimer's disease (AD) often experience negative mental health and relationship outcomes. Additionally, emotional perception abilities are often compromised in early AD; the relationships between these deficits and CG outcomes are unclear. The present study investigated the relationship between emotional perception abilities in AD participants and CG well-being.
  
  
  
  Participants included 28 individuals with AD, their spousal CGs, and 30 older controls (OCs). Patients and controls completed the Montreal Cognitive Assessment and Advanced Clinical Solutions: Social Perception subtest. CGs completed questionnaires related to relationship satisfaction, burden, depression, and patient neuropsychiatric symptoms and activities of daily living.
  
  
  
  The patient group performed significantly worse than OCs on measures of cognition and emotional perception. Several significant relationships emerged between AD participant emotional perception and CG outcomes. Higher CG depression was associated with greater overall emotional perception abilities (r = .39, p = .041). Caregiver burden was positively correlated with AD participants' ability to label the emotional tones of voices (r = .47, p = .015). Relationship satisfaction was not significantly correlated with emotional perception.
  
  
  
  This study replicated earlier findings of impaired emotional perception abilities in AD participants. However, preserved abilities in emotional perception were associated greater CG depression and burden. Interestingly, the CGs satisfaction with the marital relationship did not appear to be influenced by changes in emotional perception. Higher emotional engagement among couples in which one spouse has cognitive impairment may contribute to increased negative interactions and in turn a greater sense of burden and depression, while leaving the marital relationship preserved.
