Criteria

Eligibility for subjects scans to be used in this study is determined by subject's eligibility/enrollment in Study A01(NCT01565291) or A03(NCT01565330).

Inclusion Criteria (AD group):

• Greater than 50 years of age

• Probable AD according to the National Institute of Neurological and Communication Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria

• Mild/moderate dementia as evidenced by a Mini-Mental State Examination (MMSE) score ranging from 10 to 24, boundaries included, at screening

• History of cognitive decline gradual in onset and progressive over a period of at least 6 months

Inclusion Criteria (A01[NCT01565291] healthy volunteer group):

• 50 years of age, inclusive

• MMSE of 29 or greater

Inclusion Criteria (A03[NCT01565330] healthy volunteer group):

• 35 to 55 years of age, inclusive

• MMSE of 29 or greater

Exclusion Criteria (both groups):

• Neurodegenerative disorders other than AD, including, but not limited to Parkinson's disease, Pick's disease, fronto-temporal dementia, Huntington's chorea, Down syndrome, Creutzfeldt-Jacob disease, normal pressure hydrocephalus, and progressive supranuclear palsy

• Diagnosis of other dementing / neurodegenerative disease

• Diagnosis of mixed dementia

• Cognitive impairment resulting from trauma, hypoxic damage, vitamin deficiency, brain infection, brain cancer, endocrine disease, or mental retardation

• Clinically significant infarct or possible multi-infarct dementia as defined by the NINCDS criteria

• Evidence on screening MRI or other biomarker that suggests alternate etiology for cognitive deficit (for healthy controls, evidence suggesting the presence of AD pathology)

• Clinically significant psychiatric disease

• History of epilepsy or convulsions

• Clinically significant hepatic, renal, pulmonary, metabolic, or endocrine disturbances

• Current clinically significant cardiovascular disease

• Received investigational medication within the last 30 days
