Synaptic Density in Psychiatric Disorders Using SV2A Receptor PET Imaging With [11C]APP311
Yale University
Summary
The aim of this study is to evaluate a new SV2A tracer, \[11C\]APP311, in healthy aging and neuropsychiatric disorders including psychotic disorders and cannabis use disorders.
Description
The overall goal of this protocol is to study synaptic density in two psychiatric disorders (namely schizophrenia and other psychotic disorders, and cannabis use disorder) with this exciting new PET tracer. Secondary outcomes will include electroencephalography (EEG). A battery of EEG paradigms assessing sensory, perceptual, and cognitive functions will also be administered. The primary dependent measures will be traditional event related potentials (ERPs; e.g. latency and amplitude) as well as time X frequency analysis (inter-trial coherence and spectral power).

Interventions
- Drug[11C]APP311
It has been shown that radiotracer \[11C\]APP311 (aka \[11C\]UCB-J) displays high specificity and selectivity for the synaptic vesicle protein SV2A. Since this protein is expressed ubiquitously in active synapses, this tracer has the potential to be a general purpose tool for quantitative imaging of synaptic density.
