U.S., Oct. 31 -- ClinicalTrials.gov registry received information related to the study (NCT07906054) titled 'Ultra-high-performance Positron Emission Tomography (PET) of Synaptic Density, Reactive Astrogliosis and Tau in Alzheimer's Disease' on Oct. 08.

Brief Summary: AIM: to investigate the relationship between synaptic density, tau and reactive astrogliosis in Alzheimer's disease (AD) versus healthy controls and centenarians.

DESIGN: this cross-sectional study will recruit patients with biomarker-proven AD, age- and sex-matched healthy controls as well as centenarians. All subjects will undergo a neuropsychological evaluation and ultra-high-performance PET imaging sessions with 18F-SynVesT-1 (synaptic density), 18F-MK6240 (tau) and 18F-...
