Survey of electroencephalography usage and techniques for dogs

Area of Science:

• Veterinary Neurology
• Clinical Diagnostics

Background:

• Canine epilepsy is a common neurological disorder with potentially underreported seizures.
• Electroencephalography (EEG) offers objective diagnostic criteria for seizures and epilepsy in dogs.
• Despite its diagnostic value, EEG is perceived as rarely utilized in veterinary neurology.

Purpose of the Study:

• To investigate current practices, techniques, and challenges associated with canine EEG usage.
• To understand the extent of EEG application among veterinary neurology specialists.
• To identify barriers hindering the broader adoption of EEG in veterinary neurology.

Main Methods:

• A survey was distributed to members of the American College of Veterinary Internal Medicine (ACVIM) Neurology Specialty and the European College of Veterinary Neurology (ECVN).
• The online survey reached at least 517 specialists and trainees worldwide.
• A 35% response rate (180 participants) was achieved.

Main Results:

• Less than 50% of veterinary neurologists currently perform EEG, and it is used infrequently.
• Primary indications include discrete event diagnosis, treatment monitoring, and seizure/epilepsy type identification.
• Key barriers identified were equipment availability, insufficient case volume, and client financial constraints.

Conclusions:

• The study updates current EEG usage and techniques in canine neurology, revealing commonalities and areas for improvement.
• Harmonization of canine EEG techniques is needed.
• A standardized canine EEG protocol could enhance the diagnosis and management of canine epilepsy.
