The Blessed Dementia Scale (including Blessed Dementia Rating components) is a classic observer/informant-based instrument for assessing changes in everyday performance, habits, and personality related to dementia progression.
Formula: Blessed total is a summed observer/informant score, higher values indicating greater impairment.
Blessed scales have longstanding historical and clinical use in dementia severity characterization.
Higher Blessed totals indicate more severe functional-cognitive decline and higher care-dependency signal.
Use when caregiver-observed functional decline data are needed for dementia staging context.
Older scale structure and informant dependence can limit comparability across modern care settings.
For related assessments, see QDRS, IQCODE-26 and Pfeffer FAQ.
