Accepts healthy volunteers: yes
Allocation: NON_RANDOMIZED
Intervention model: SINGLE_GROUP
Primary purpose: DIAGNOSTIC

Brief summary: This study will test if two AV-45 PET scans up to 4 weeks apart in AD subjects and healthy volunteers provide the same results. The study will also test two different AV-45 injection methods in a small subgroup of enrolled AD subjects (slow vs. fast bolus group).


Eligibility criteria: 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 (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
