Characterizing visual read tau-PET-negative participants with Alzheimer's disease dementia
INTRODUCTION: A subset of amyloid beta (Aβ)-positive Alzheimer's disease (AD) patients is tau-positron emission tomography (PET) negative. We aimed to characterize this subgroup using [18F]flortaucipir PET visual read (VR), as this is important for prognosis and selection for therapies. METHODS: Aβ-positive VR tau-PET-negative AD dementia patients (AD A+T−) were compared to tau-PET-positive AD pat
