Imaging Synapses With [11C] UCB-J in the Human Brain

Conditions

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this study is to utilize the radioactive positron emission tomography (PET) tracer \[11C\]UCB-J to test the neural synaptic pruning hypothesis of schizophrenia. This imaging method allows for the quantification of synaptic density in the living human brain and has the unprecedented ability to directly examine the synaptic pathology underlying neuropsychiatric disease. The neural synaptic pruning hypothesis posits that a key pathogenic process of schizophrenia is the over-exuberant elimination of neural synapses during development. The confirmation of reduced synaptic density in schizophrenia as evidenced by \[11C\]UCB-J has the potential to lead to a number of ground-breaking clinical innovations, such as laboratory-based diagnostics and prognostics, and novel, disease-modifying treatments.
