From mild behavioral impairment-checklist (MBI-C) to MBI-distress (MBI-D): a paired assessment and clinical correlates of domain-specific caregiver distress in MCI due to AD

The MBI-D, strongly coupled with MBI-C, is a concise, clinically practical and scalable measure of MBI-related caregiver distress in MCI-AD, capturing both symptom burden and domain-specific distress in a single administration. Impulsivity, apathy, and affective dysregulation are highlighted as priority targets for early, caregiver-focused interventions advancing innovative, prevention-oriented dementia care delivery.
