Brief Summary:
The purpose of this study is to learn whether blood flow in the brain is normal in people with pantothenate kinase-associated neurodegeneration (PKAN). Specifically, preliminary data suggest a region of the brain called the globus pallidus (GP), a key region affected by PKAN, may have reduced blood flow. Standard MRI and perfusion scanning techniques will be used to learn about cerebral blood flow in the globus pallidus and compare it to blood flow in other brain regions as well as to healthy controls.

Study Type : Observational
Actual Enrollment : 10 participants
Observational Model: Case-Control
Time Perspective: Cross-Sectional
Official Title: Brain Perfusion in Pantothenate Kinase-Associated Neurodegeneration (PKAN)
Actual Study Start Date : April 2013
Actual Primary Completion Date : October 2017
Actual Study Completion Date : January 2018

This group consists of individuals diagnosed with PKAN using a combination of MRI and PANK2 gene sequencing.
Healthy volunteers
This is a control group of healthy volunteers, matched with the PKAN group for age and sex.

Primary Outcome Measures :
  1. ASL-derived cerebral blood flow(CBF) [ Time Frame: Single MRI ]
    The unit of analyses will be the subject and the primary comparison will be the globus pallidus CBF between PKAN and healthy controls.
