“…No known triggers were reported and no association between feeding and ES were found. The latter have been reported in a group of dogs, nine of which were diagnosed with IE ( 31 ). Most (67%) of the dog owners thought their dogs were not conscious during the seizures.…”

Phenotypic characterization of idiopathic epilepsy and epilepsy of unknown cause in Irish Setters

Canine epileptic seizures are common neurological symptom presenting to veterinary practice. Idiopathic epilepsy (IE) with a suspected genetic background has been reported in several dog breeds. Although it has been reported in the Irish Setter (IS), the phenotypic characteristics have not yet been described. The aim of this study was to characterize the phenotype of IE in this breed and to trace its mode of inheritance.Owners of IS were requested to fill in a questionnaire via the Dutch Irish Setter Club concerning the epileptic seizures in their dogs. The data was assessed retrospectively using descriptive statistics. Forty-eight privately owned IS dogs fulfilling tier I criteria for IE according to the International Veterinary Epilepsy Task Force of both sexes were included in the study. The mean age of seizure onset was 41 months. Five of the dogs included in the study had an onset of seizures >6 years of age. These dogs were classified with epilepsy of unknown cause (EUC). Primary generalized tonic-clonic seizures were the most common type of seizure and were seen in almost all dogs. Cluster seizures were reported in 54% of the studied population. Most owners reported pre- (56%) and post-ictal (97%) signs in their dogs. A pedigree analysis of one subpopulation was performed and traced the lineage of 13 affected IS. A segregation analysis of this population rejected a simple autosomal recessive inheritance pattern. The present study supports the occurrence of IE and EUC in the IS. The results provide clinical insight into epileptic seizures in this breed and may be a starting point for further, including genetic, analysis.

“…Of the 10 dogs in the study, six experienced cluster seizures. While four of the 10 dogs experienced seizures in the middle of the meal, six of the 10 dogs occurred at the beginning of meals 10 . In our case, some of the seizures were reported when the dog was eating or immediately after feeding, and as such this form of seizure manifestation could have been a possible differential diagnosis.…”

A 4‐month‐old female entire Cavalier King Charles Spaniel was referred for investigation into a 3‐week history of suspected focal onset seizures, characterised by head nodding and eyelid twitching. An inflammatory soft‐tissue reaction surrounding a suspected foreign body (FB) in the subcutaneous tissue and muscles at the level of the left maxilla in the caudal aspect of the left maxillary second molar was detected using MRI. The presence of the FB was confirmed ultrasonographically. This was found to be a grass seed upon surgical removal. The previously reported clinical signs resolved immediately after the surgery. It was suspected that the FB and secondary inflammatory reaction incited a form of trigeminal neuralgia manifesting as paroxysmal head nodding and facial twitching. A form of trigeminal neuralgia should be included in the differential diagnosis of facial focal motor seizures and should be investigated accordingly before initiating any antiepileptic treatment.

“…Recently, epileptic seizures triggered by eating in dogs are also reported. 34 Although atonic seizures in dogs with "eating epilepsy" might be a phenotypical differential diagnosis for cataplexy episodes triggered by eating, atonic seizures have not been reported in this type of reflex seizure in dogs. There are low levels of agreement between veterinary neurology specialists and nonspecialists in the interpretation of videos of canine and feline paroxysmal events.…”

“…With regard to the dogs included and the videos in Supplementary file 2, other possible causes for the episodes observed or events such as these could include myoclonus or atonic seizures. Recently, epileptic seizures triggered by eating in dogs are also reported 34 . Although atonic seizures in dogs with “eating epilepsy” might be a phenotypical differential diagnosis for cataplexy episodes triggered by eating, atonic seizures have not been reported in this type of reflex seizure in dogs.…”

Background: Acquired narcolepsy has rarely been reported in veterinary medicine.Objective: To describe the presentation, clinicopathological features, diagnostic imaging findings, and management of dogs with suspected-acquired narcolepsy.Animals: Eight dogs with clinical features consistent with acquired narcolepsy.Methods: A call for suspected cases of acquired narcolepsy was made online, followed by a retrospective review of detailed medical records of potential cases. Dogs were included if episodes consistent with cataplexy were present during examination by a board-certified veterinary neurologist and diagnostic work-up included magnetic resonance imaging of the brain and analysis of cerebrospinal fluid.Results: Seven French Bulldogs and 1 Chihuahua (age range, 9-66 months) were included. Meningoencephalitis of unknown origin was diagnosed in 2 dogs, extracranial foci of inflammation were identified in 2 dogs (aspiration pneumonia, esophagitis, otitis media), and no abnormalities were found on diagnostic investigations in 4 dogs.Prednisolone was used in the management of all dogs, 6 dogs received imipramine, and 2 received cytosine arabinoside. An initial remission of signs was observed in all dogs, but a subsequent relapse of clinical signs was recorded for 4 dogs, of which 3 responded to adjustment or resumption of treatment.Conclusions and Clinical Importance: The presence of cataplexy episodes should prompt a thorough diagnostic work-up to exclude the presence of intracranial (and extracranial) pathology. The potential for both remission and relapse of signs in suspected acquired cases is important for clinicians and owners to be aware of.
