Eligibility criteria

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

What researchers measure

Primary outcomes

  1. Mean Cortical to Cerebellum SUVR

    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.

    Time frame: 50-60 min after injection

Secondary outcomes

  1. Precuneus to Cerebellum SUVR

    Ratio of uptake in the precuneus to uptake in the cerebellum.

    Time frame: 50-60 min after injection
