Quality of life scores of patients and caregivers

	MCI	Mild AD	Moderate AD	Severe AD	Total AD
	N = 27	N = 27	N = 25	N = 21	N = 73
DEMQOL-Proxy score	93.3±8.6	85.3±12.2	91.2±11.7	65.2±19.2	81.5±17.8
CarerQoL-7D utility score	80.8±9.1	74.2±12.0	77.7±12.8	78.9±11.9	76.7±12.3
DS	6.7±2.9	6.4±2.6	7.4±3.5	11.8±2.7	8.3±3.7

Values are expressed as mean±standard deviation. Note: DEMQOL-Proxy can range from 31 to 124, with higher scores indicating enhanced patient QoL. CarerQoL-7D utility scores can range from 0 to 100, with higher scores indicating enhanced caregiver QoL. The DS can range from 0 to 15, with higher scores indicating greater levels of patient dependence.
