AI takes on nerve disease diagnosis: ChatGPT matches specialists?
NCT ID NCT07493681
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether ChatGPT-4o could correctly diagnose polyneuropathies (nerve diseases) in 100 real patients. Researchers compared the AI's answers to those of nerve specialists and general neurologists. The goal was to see if AI can help non-specialist doctors make better diagnoses.

Who is studied
Cases will be identified from patients with a confirmed diagnosis of polyneuropathy consecutively attending the polyneuropathy outpatient clinics of the two participating institutions. Demographic, clinical, and diagnostic data will be extracted from medical records at two time points: the initial neurological consultation and the first follow-up visit after completion of standard screening investigations, including laboratory tests and nerve conduction studies.
