Symptoms of epilepsy

Most people are familiar with what is referred to as a generalised or grand mal seizure.

Seizures can come in other forms such as repeated, involuntary behaviours (referred to as psychomotor) or repeated movements of a particular part of the body (focal seizures).

Seizures can be divided into three phases:
  1. Pre-ictal phase: The change in behaviour that occurs before the seizure event (ie pacing, nervousness, hyperactivity, attention seeking)
  2. Ictal phase: The seizure event itself
  3. Post-ictal: A period after the seizure event where there is display of abnormal behaviours such as lethargy, confusion or a voracious appetite. The length of the post-ictal phase can vary from minutes to hours.

What causes epilepsy in dogs and cats?

There are numerous causes of seizures and can include:

Idiopathic epilepsy can occur at any age but is most commonly diagnosed in young and middle aged pets and tends to occur more regularly in males than females.

Breeds commonly affected by epilepsy are Border Collies, Labradors, Beagles, Australian Shepherds, Hungarian Vizslas, Golden retrievers, German Shepherds and Poodles.

A breed or genetic association has not been as strongly proven in cats as it has in dogs.

Diagnosis of epilepsy

Because there are numerous causes of seizures often multiple tests are needed to determine the cause of epilepsy. Investigation usually includes blood tests and urine tests to check for problems outside the brain and imaging such as CTs or MRIs to check for structural changes in the brain. Referral to a veterinary neurologist is sometimes recommended.

If all the tests come back normal then this is when the epilepsy is referred to as idiopathic.

Treatment of Epilepsy

Currently there is no cure for idiopathic epilepsy so treatment is aimed at management. Depending on how frequent and severe the seizures are your veterinarian may prescribe anti-seizure medication. The aim of treatment is to reduce the seizures enough to ensure a good quality of life. If the seizures are caused by another issue such as a tumour or metabolic disease then treatment is aimed at controlling or treating these primary causes.

Some recent studies have also shown that dietary change may help some patients with epilepsy management.

What to do if your pet is having a seizure

  • Move away objects or furniture from your pet to avoid them injuring themselves
  • Keep other animals or children away from the pet
  • Keep your hands away from their mouth to avoid being accidentally bitten
  • Try to time how long the seizure goes for. Seizures lasting longer than 5 minutes or having multiple seizures within a short period of time can be an emergency and your pet should be checked by a vet asap
  • Keep your pet in a safe, calm and dimly lit environment after a seizure until he/she recovers from the post-ictal phase

Prognosis for Epilepsy in Pets

Once diagnosed epilepsy is a chronic disease that usually requires lifelong medication and management. As most animals are normal between seizures those with well managed epilepsy are able to live a good quality of life.
