Emotional Recognition: A Comparative Study of People with Mild Cognitive Impairment and Alzheimer's Disease Self-Report with Caregiver Perspectives.

Objective: This study compared emotional recognition in participants with mild cognitive impairment (MCI) and mild to moderate Alzheimer 's disease (AD) against caregivers' perceptions of these participants' emotional states, while exploring the influence of clinical variables. Methods: We included 141 participants (32 with MCI, 50 with mild AD, and 59 with moderate AD) and their primary caregivers. We employed tasks assessing emotional decoding, identification, and correspondence, along with objective evaluations. Results: Participants across all groups showed significant differences in cognition and functionality. However, emotional recognition abilities did not significantly differ between MCI and mild or moderate AD groups. Most cognitive and neuropsychiatric variables had no significant impact on emotion recognition or social functioning. No differences emerged in patients' self-evaluations of social and emotional functioning. Caregiver assessments revealed significant differences only between the MCI and moderate AD groups. Conclusion: Participants with MCI and AD displayed expected clinical progression while retaining some emotional recognition and social functioning capabilities.
