Overview

Analysis reveals cognitive decline and emotion recognition deficits in mild cognitive impairment, indicating possible neurodegenerative impacts.

Key Points

  • This research examines the relationship between mild behavioral impairment and cognitive/socio-emotional profiles using EEG analysis.
  • Participants included 120 older adults with subjective cognitive decline or mild cognitive impairment.
  • Groups were categorized into mild behavioral impairment and non-mild behavioral impairment using the MBI-Checklist.
  • Neuropsychological evaluations included Mini-Mental State Examination and Korean Facial Affect Battery subtests.
  • The mild behavioral impairment group exhibited greater functional impairment and depressive symptoms.
  • Significant deficits in facial emotion recognition, especially in affect selection, were noted in the MBI group.
  • EEG analysis revealed altered spectral power and connectivity patterns in the MBI group.
