Lead Sponsor:

Institute for Neurodegenerative Disorders

Conditions:

Parkinson Disease

Eligibility:

All Genders

30-50 years

Phase:

PHASE1

Brief Summary

To assess the dynamic uptake and washout of 123-I CLINDE, a potential imaging biomarker for inflammatory changes in brain, using single photon emission computed tomography (SPECT) in similarly aged he...

Detailed Description

When microglia become activated they express peripheral benzodiazepine receptors (PBR) or binding sites on their mitochondrial membrane. PBRs are functionally and structurally distinct from central be...
