Study supports teleneurology for lesion localization in dogs and cats

A new study in the Journal of the American Veterinary Medical Association points to a practical use case for veterinary telemedicine: neuroanatomic lesion localization in dogs and cats. The research evaluated whether neurologists could reach similar localization conclusions from prerecorded or live-streamed neurologic examinations as they would in person, and the early answer appears to be yes. In a 55-patient prospective study, both video formats showed strong agreement with blinded in-person assessments, suggesting teleneurology may be more clinically useful than many teams have assumed.

That question has been hanging over veterinary telehealth for several years. Telemedicine expanded rapidly after the COVID-19 pandemic, but most of the established specialty infrastructure in veterinary medicine has centered on areas like teleradiology, telecardiology, and telepathology. The Virginia Tech group behind this study framed teleneurology as a gap area, noting that while telecommunication is common in other specialties, the accuracy of remote neurolocalization had not been well studied in veterinary patients.

According to the conference abstract and associated report, the study enrolled 55 client-owned animals presenting to a neurology service. Veterinary students performed the neurologic examinations. One cohort included 30 dogs whose exams were recorded and reviewed later by a neurologist, while another cohort included 25 patients whose exams were live streamed to a neurologist who could interact with the examiner during the visit. Each patient was then examined in person by a neurologist or third-year neurology resident who was blinded to the teleneurology findings. The investigators’ hypothesis was that teleneurology would show strong agreement with in-person localization, and that prerecorded video might perform less well than live streaming. The reported results showed strong agreement for both models, with the recorded group showing a kappa around 0.84 to 0.85 and a highly significant chi-squared result in the earlier abstract.

The study also matters because it comes from a referral environment with a substantial neurology caseload. Virginia Tech has described its neurology and neurosurgery service as a regional referral center serving patients from multiple states, with a faculty team that combines clinical care, research, and teaching. That context likely helped standardize examinations and interpretation, but it also means the findings may represent a best-case academic setting rather than the variability of primary care practice or home video captured by pet parents. That limitation is implied by the authors’ own call for more work involving primary care veterinarians and pet parents. (news.vt.edu)

Industry context supports the relevance of that next step. AAHA has noted that veterinary teams are still working through when telemedicine is appropriate, how to charge for it, and how VCPR rules differ by state. In parallel, specialty telemedicine frameworks are becoming more formalized elsewhere in veterinary medicine. A 2024 ACVR-ECVDI consensus statement set best-practice guidance for veterinary teleradiology, underscoring that remote specialty interpretation is already an accepted part of care when quality and safety standards are defined. Teleneurology may now be moving toward a similar evidence-building phase. (aaha.org)

Why it matters: For veterinary professionals, the most immediate implication is triage. If remote neurologic exams can reliably localize lesions, even at a basic level, that could help general practitioners and ER teams decide which patients need urgent transfer, advanced imaging, or same-day specialty consultation. It may also improve access for practices in regions where boarded neurologists are scarce. At the same time, localization agreement is not the same as a full diagnosis, and this study does not resolve the legal, operational, or reimbursement barriers that still shape telemedicine adoption. The findings are promising, but they support teleneurology as an adjunct to clinical decision-making, not a replacement for hands-on examination, imaging, or follow-up care. (academic.oup.com)

What to watch: The key next milestone will be validation in real-world referral pathways, especially exams performed by primary care teams or video captured at home by pet parents, along with clearer protocols for when prerecorded video is enough and when live specialist guidance adds value.
