  Description
Alzheimer's Disease Subject's with Alzheimer's Disease were recruited from study 18F-AV-45-A05 (NCT00702143). None of these subjects received additional interventions in study 18F-AV-45-A11.
Mild Cognitive Impairment Subject's with Mild Cognitive Impairment (MCI) were recruited from study 18F-AV-45-A05 (NCT00702143). 36 of these subjects received a single dose of florbetapir F 18 370 MBq (10 mCi), IV injection at the 24 month time point of study 18F-AV-45-A11 and comprise the safety set discussed in the Adverse Events section.
Cognitively Normal Cognitively Normal (CN) subjects were recruited from study 18F-AV-45-A05 (NCT00702143). 50 of these subjects received a single dose of florbetapir F 18 370 MBq (10 mCi), IV injection at the 24 month time point of study 18F-AV-45-A11 and comprise the safety set discussed in the Adverse Events section.
