Canine Epilepsy: Diagnosis and Management Strategies
Summary
Epilepsy is one of the most prevalent chronic neurological disorders in the domestic dog and poses significant challenges to veterinary clinicians and owners alike. The condition is defined by recurrent, unprovoked seizures resulting from abnormal electrical activity in the canine brain. Effective management hinges on early and accurate diagnosis, encompassing detailed clinical history, neurological examination and advanced diagnostics such as magnetic resonance imaging and electroencephalography to differentiate idiopathic epilepsy from structural and reactive causes. Once diagnosed, therapeutic strategies centre on long-term antiepileptic drug regimens aimed at seizure control while minimising adverse effects. Phenobarbital, potassium bromide and imepitoin remain first-line choices in many regions, often complemented by newer agents such as levetiracetam. Adjunctive measures address quality of life through dietary modification, behavioural interventions and regular monitoring of drug serum levels. Despite advances, a subset of dogs exhibit pharmacoresistance or intolerable side effects, prompting research into alternative treatments, including ketogenic diets and neuromodulation. Integrating consensus guidelines with emerging evidence supports personalised management plans that balance seizure suppression, safety and owner expectations.

Canine Epilepsy: Diagnosis and Management Strategies publication trend
The graph below shows the total number of articles in canine epilepsy: diagnosis and management strategies across all publications each year (not limited to Nature Index journals).
Technical terms
Idiopathic epilepsy: Syndrome of recurrent seizures with no identifiable structural or metabolic cause.
Electroencephalography (EEG): Recording of electrical activity from the scalp to detect seizure patterns.
Magnetic resonance imaging (MRI): Imaging technique that visualises brain structure to exclude lesions.
Cluster seizure: Two or more seizures occurring within a 24-hour period in the same patient.
Pharmacoresistance: Failure to achieve adequate seizure control despite appropriate antiepileptic drug therapy.
Ketogenic diet: High-fat, low-carbohydrate nutritional regimen that induces ketosis and may reduce seizures.
