  • Parkinson's affects many people across the United States.
  • The disease slowly destroys brain cells that control movement.
  • Tremor and other symptoms appear later in patients.
  • Because of this, early detection is very important.
  • Doctors use special brain scans to see changes.
  • Scans measure markers that show brain health.
  • In healthy brains the markers rise and fall together.
  • In people with Parkinson's this link becomes weaker.
  • Researchers compared patients with healthy volunteers using scans.
  • The results may help study disease development and treatment.
