Table 1.

Capacity status of persons with Alzheimer’s disease, for three different decision-making tasks, as determined by a 5-expert panel

	Capacity to Appoint Proxy (n=188)^*	Capacity to Consent to Drug RCT (n=181)^*	Capacity to Consent to Neurosurgical RCT (n=186)^*
	N (%)	N (%)	N (%)
Capacity	116 (61.7)	75 (41.4)	29 (15.6)
3 judges agree	32 (17.0)	20 (11.0)	8 (4.3)
4 judges agree	27 (14.4)	30 (16.6)	14 (7.5)
5 judges agree	57 (30.3)	25 (13.8)	7 (3.8)
No capacity	72 (38.3)	106 (58.6)	157 (84.4)
3 judges agree	23 (12.2)	21 (11.6)	19 (10.2)
4 judges agree	26 (13.8)	29 (16.0)	34 (18.3)
5 judges agree	23 (12.2)	56 (30.9)	104 (55.9)

The numbers are different because 188 completed the first interview which included the CAPA and either the drug RCT or the neurosurgical RCT MacCAT-CR (randomly chosen), 7 declined the second MacCAT-CR interview, and one subject finished neither of the MacCAT-CR interviews.
