Plain-English summary
Three dogs were brought to the vet because they were having repeated episodes of drooling, vomiting, gagging, and showing signs of stomach pain. When the vets checked them between episodes, everything seemed normal. However, special brain wave tests called EEGs showed unusual activity that indicated they were having focal autonomic seizures, which are seizures that can affect the body's automatic functions. After starting treatment with anti-seizure medications, the dogs showed a significant improvement in their symptoms.
Abstract
In human medicine, focal seizures can clinically express as autonomic signs, such as gastrointestinal dysfunction, cardiovascular changes, and variation of pupillary size; but little is known about possible presentations of autonomic seizures in veterinary medicine. Three dogs were presented for recurrent episodes characterized by hypersalivation, vomiting, retching, and signs of abdominal discomfort. Neurological examinations were normal between episodes. Electroencephalographic (EEG) recordings identified ictal or interictal epileptiform discharges in all dogs. Based on clinical signs and EEG findings, a diagnosis of focal autonomic seizures was made. There was a notable positive response of clinical signs to antiepileptic treatment. These cases highlight the diverse clinical presentations of focal autonomic seizures in dogs and emphasize the diagnostic value of EEG in these cases.
