Novel experimental test may aid early diagnosis of Parkinson’s disease

  • Parkinson’s disease is a neurodegenerative disorder that affects more than 10 million people worldwide.
  • Symptoms, which include tremors, muscle stiffness, and impaired mobility, are believed to be caused by build up of alpha-synuclein fibrils that impair the function of nerve cells.
  • There are currently no diagnostic tests for Parkinson’s disease, meaning that doctors usually diagnose the disorder by taking a person’s medical history and carrying out a neurological examination once symptoms are advanced.
  • Now, researchers have developed a technique to detect and quantify alpha-synuclein fibrils, which may lead to early tests to diagnose Parkinson’s.
