Experimental: FTD Subjects
Subjects diagnosed by dementia specialist with a clinical Frontotemporal Dementia (FTD) syndrome and expected tau or tar DNA binding protein (TDP)-43 pathology receiving a flortaucipir PET scan

Drug: Flortaucipir F18
370 megabecquerel (MBq)(10 millicurie [mCi]) injection, single dose

Procedure: Brain PET scan positron emission tomography (PET) scan of the brain |
- Qualitative Evaluation of Flortaucipir PET Scans [ Time Frame: baseline scan ]Subject scans were visually evaluated by an expert reader into three groups. Advanced Alzheimer's Disease (AD) scan pattern = In either hemisphere, increased neocortical activity in the parietal/precuneus region(s), or frontal region(s) with increased uptake in the posterolateral temporal (PLT), parietal, or occipital region(s). Moderate AD scan pattern = In either hemisphere, increased neocortical activity limited to the PLT or occipital region(s). Not AD scan pattern = No increased neocortical activity, or increased neocortical activity isolated to the mesial temporal, anterolateral temporal, and/or frontal regions.
- Quantitative Evaluation of Flortaucipir PET Scans [ Time Frame: baseline scan ]Standard Uptake Value Ratio (SUVr) using a weighted cortical average (MUBADA), and individual regions. For SUVr, a value of 1 or lower signifies no flortaucipir activity above background, values greater than 1 signify increasing flortaucipir activity in the brain.

- Can tolerate PET scan procedures
Exclusion Criteria:
- Have clinically significant cardiac, hepatic, renal, pulmonary, metabolic, or endocrine disturbances that pose potential safety risk
- Have history of risk factors for Torsades de Pointes (TdP) or taking medication known to cause QT prolongation
- Have history of drug or alcohol dependence within the last year
- Are females of childbearing potential who are not surgically sterile, not refraining from sexual activity, or not using reliable contraception
- Have history of relevant severe drug allergy or hypersensitivity
- Have received an investigational medication under FDA IND protocol within 30 days of planned imaging session
- Have received a radiopharmaceutical for imaging/therapy within 24 hours of imaging session
- Possess PET scan evidence of amyloid deposition
- Determined by the investigator to be unsuitable for this type of study
