Primary Outcome Measures

Name	Time	Method
Main Objective: Use florbetapir 18F PET imaging to investigate the pathological underpinning of the neuropsychologically distinct variants of progressive aphasia and compare these patterns of florbetapir 18F uptake with typical Alzheimer's disease and age-matched controls;Secondary Objective: To investigate associations between focal brain atrophy, cortical thickness and regional amyloid uptake in amyloid positive variants of these syndromes;Primary end point(s): Quantitative and qualitative assessments of florbetapir 18F uptake to test the primary hypotheses;Timepoint(s) of evaluation of this end point: Complete imaging of all subjects

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): Descriptive assessment of the focality and asymmetry of amyloid uptake and glucose hypometabolism between various groups;Timepoint(s) of evaluation of this end point: Complete imaging of all subjects
