  • MOCA Score greater than or equal to 24 determined by a NIH neurologist
  • Hoehn and Yahr Score less than or equal to 3 determined by a NIH neurologist
  • Asymmetric motor symptoms
  • EXCLUSION CRITERIA:
  • Any current major neurological or psychiatric disorder other than Parkinson s disease, such as, (but not limited to) stroke, dementia, Alzheimer disease, Schizophrenia or Major Depression Disorder

  • Members of the Behavioral Neurology Unit, NINDS
  • Left-handed per the Edinburgh Handedness scale
  • Primarily axial motor symptoms or symmetrical limb involvement
  • Pregnancy
  • Exclusion criteria for MRI
  • Presence of metal which would make having an MRI scan unsafe, such as pacemakers, stimulators, pumps, aneurysm clips, metallic prostheses, artificial heart valves, cochlear implants or shrapnel fragments, or if subject was a welder or metal worker, since small metal fragments may be present in the eye.
  • Claustrophobia
  • Inability to lie supine comfortably for 1 hour
  • Pregnancy
  • INCLUSION OF VULNERABLE PARTICIPANTS:
  • Because the goals of the study can be accomplished without involving vulnerable population, we will not include individuals without consent capacity.
  • Since the goal is to characterize visuospatial attention deficits in idiopathic PD which is a disease of late adulthood, we will not include children.
  • The effects of MRI on fetal development and the health of pregnant women is unknown.
  • Therefore, women who are pregnant and breast-feeding will be excluded and women who can become pregnant will be excluded following a positive pregnancy test, if the optional MRI is under consideration.
  • The study requires fluency in English in order to completely understand tasks instructions, thus non-English speakers/readers will be excluded.
