Epilepsy in animals

Epilepsy in animals is a group of neurological disorders characterized by seizures, caused by abnormal bursts of electrical activity in the brain. They can start and stop very abruptly and last any amount of time from a few seconds to a few minutes. Canine epilepsy is often genetic but epilepsy in cats and other pets is rarer, likely because there is no hereditary component to epilepsy in these animals.

Epilepsy is most commonly recognised by involuntary movements of the head and limbs, however other characteristics include salivation, lack of and anxiety. Animals often lose consciousness and are not aware of their surroundings.

Watching an animal have a seizure can be quite frightening. There is not much that can be done during a seizure except to remain calm and not leave the animal alone. If your pet is having a seizure it is important to make sure they are laying down on the floor away from any water, stairs or other animals. When an animal has a seizure, do not try to grab their tongue or clear their mouth as there is a high chance you will be bitten; contrary to popular myth, neither humans nor animals can "swallow their tongue" during a seizure so it is safest to stay well away from their mouth during one. Timing seizures is also crucial. Take notes of seizures - what time they occur, how often and any other specific information which can be passed onto the vet or emergency animal clinic.

In dogs, epilepsy is often an inherited condition. The incidence of epilepsy/seizures in the general dog population is estimated to be between 0.5% and 5.7%. In certain breeds, such as the Belgian Shepherd, the incidence may be much higher.

There are three types of epilepsy in dogs: reactive, secondary, and primary. Reactive epileptic seizures are caused by metabolic issues, such as low blood sugar or kidney or liver failure. Epilepsy attributed to brain tumor, stroke or other trauma is known as secondary or symptomatic epilepsy.

There is no known cause for primary or idiopathic epilepsy, which is only diagnosed by eliminating other possible causes for the seizures. Dogs with idiopathic epilepsy experience their first seizure between the ages of one and three. However, the age at diagnosis is only one factor in diagnosing canine epilepsy, as one study found cause for seizures in one-third of dogs between the ages of one and three, indicating secondary or reactive rather than primary epilepsy.
