Eye scans and voice tests may spot Parkinson's without needles
NCT ID NCT07201610
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study explores painless ways to diagnose Parkinson's disease using advanced eye imaging, memory tests, and voice analysis. Researchers will compare results from 60 people with and without Parkinson's to see if these methods can accurately identify the disease. The goal is to replace invasive spinal taps with simple, office-based tests.

Who is studied
Thirty consecutive patients with a diagnosis of idiopathic Parkinson's disease who are scheduled for routine follow-up visits at the Neurology Clinic in Karlskrona. After patient recruitment, 30 healthy controls matched by age and gender (1:1 matching) will be recruited from Blekinge Institute of Technology's (BTH) Research and Development Clinic. At the clinic, there is a list/mailbox where individuals can volunteer to participate in studies. The participants who best match the included Parkinson's patients will be invited to take part
