Note.

*

Total number does not equal sum of PiB- and PiB+ given that PiB status could only be determined on 56 participants at Cycle 1 and 54 participants at Cycle 2. Mental age was assessed using the Stanford-Binet, Fifth Edition Abbreviated Battery (Roid, 2003), DSDS-CCS = Down Syndrome Dementia Scale (Gedye, 1995) – Cognitive Cutoff.
