• 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
