Metabotropic Glutamate Receptor 5 (mGluR5) Imaging in Amyotrophic Lateral Sclerosis (ALS) Patients and Healthy Volunteers

Study Purpose:

This is a pilot study to evaluate a potential imaging biomarker for aiding diagnosis and monitoring progression of ALS, based on a well established basic science pathway, published human autopsy data, preliminary data in ALS mutant mice, and our recently published data using brain PET scans to image the metabotropic glutamate receptor type 5 (mGluR5) in healthy human volunteers.
