Seizures are caused by abnormal electrical activity in the brain. A seizure is considered to be a clinical sign/symptom of an underlying disease process. Seizures by themselves are not a disease. The most common cause of seizures is idiopathic epilepsy, which means scientists and doctors don’t know what specifically cause them. Other causes of seizures may be due to liver or kidney disease, nutritional deficiencies, brain tumors, certain infections, trauma, or toxin/poison ingestion.
No matter how many seizures your pet has or how severe they are, it is important to bring it up to your veterinarian so they can be further investigated and better managed!
