Epidemiological and clinical insights into canine epilepsy: A retrospective study in southern Brazil

Epilepsy is a common neurological disorder in dogs, characterized by recurrent seizure episodes that can significantly impact quality of life. This retrospective study analyzed 116 dogs treated in 2023 and 2024, evaluating clinical and epidemiological factors associated with epilepsy and other neurological conditions. Data were collected from clinical consultations, laboratory tests, and imaging exams. Idiopathic epilepsy was the most frequent cause of seizures, primarily affecting young adult dogs (mean age: 5.27 ± 2.75 years), with no significant sex predisposition (p > 0.05). Mixed-breed dogs were the most commonly affected, although certain pure breeds - such as French Bulldogs, Siberian Huskies, and Yorkshire Terriers - showed increased representation. Ischemic stroke was rare, reinforcing that seizures are not a predominant manifestation of this condition. Intracranial tumors were mainly observed in elderly dogs (aged over 10 years), with meningioma being the most common, underscoring the importance of early neurological evaluation. This study contributes to a better understanding of epilepsy in dogs in southern Brazil, supporting differential diagnosis and clinical decision-making. The findings also highlight the importance of advanced diagnostics and individualized treatment plans. Given the complexity of epilepsy, further research is needed to improve understanding of its causes, diagnostic approaches, and treatment strategies, ultimately enhancing the prognosis and quality of life of affected dogs.
