Mean Cortical to Cerebellum SUVR [ Time Frame: 50-60 min after injection ]
Standardized Uptake Value ratio (SUVR) is the ratio of tracer uptake in predefined cortical regions, relative to uptake in the cerebellum gray matter. Total scan length was 200 min.
Mean Cortical Standardized Uptake Value (SUV) [ Time Frame: 50-60 min after injection ]

Average of SUVs from the following cortical regions determined by brain PET scan: frontal cortex, temporal cortex, parietal cortex, occipital cortex, anterior cingulate, posterior cingulate, precuneus.

SUV=An automated process to extract estimates of tracer retention on a PET scan from prespecified standard volumes of interest.

Inclusion Criteria (AD group):

  • 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 exam (MMSE) score ranging from 10 to 24, boundaries included, at screening
  • History of cognitive decline had been gradual in onset and progressive over a period of at least 6 months

Inclusion Criteria (healthy volunteer group):

  • No evidence of significant cognitive impairment by history and psychometric testing
  • MMSE of 29 or higher

Exclusion Criteria (both groups):

  • Neurodegenerative disorders other than AD
  • 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
