In accurately diagnosing a pet with epilepsy, our veterinarians rely heavily on pet-owner cooperation. The process of diagnosis requires close observation and recording of a pet’s seizure activity outside of our veterinary office, as well as observation from the vet. Epilepsy is a disease that has symptoms similar to other diseases; when possible, video and written records of episodes of seizures greatly improve accurate diagnoses, and we appreciate you actively participating in your pet’s treatment.
In all cases, the cause of epilepsy is difficult to determine. Some predisposing factors include bacterial/viral encephalitis, brain malformations, brain trauma, brain tumor(s), high fever, genetic and hereditary factors, metabolic disturbances (such as low blood sugar or liver disease), and stroke. When the onset of epilepsy can be determined, it is considered Secondary Epilepsy. If the reason for seizures cannot be established, it is referred to as Idiopathic Epilepsy.
Types of seizures in pets
• Cluster: numerous seizures within a short span of time, allowing very short periods of consciousness between each seizure. Cluster seizures are extremely dangerous, as they can cause permanent brain damage or even be fatal.
• Complex partial: involves behaviors that are continually repeated throughout the seizure. In otherwise normal pets these behaviors include biting, chewing, hiding, vocal noises, running. These are very uncommon types of seizures.
• Partial: seizure-like jerking movement limited to specific areas of the body. (i.e. localized muscle spasms, facial twitches).
• Petit mal: there are several different indications of a petit mal seizure and all do not necessarily occur at once. Some pets shake their head left and right for a few minutes: others’ entire bodies shake throughout the extent of the seizure. Some pets blankly stare with a glazed look while others continuously blink while arching their backs.
• Status epilepticus: life threatening emergency of a continuous seizure lasting longer than 30 minutes, or a series of multiple seizures in a short time without periods of consciousness in between. Permanent brain damage or even death can result.
• Tonic-clonic: a pet typically falls over, losing consciousness and extending its limbs to a rigid outstretched position. Breathing stops for a short period of 10-30 seconds until the convulsing movements begin which can include chewing or making a paddling motion with the limbs. Some dogs exhibit dilated pupils, excessive drooling, and incontinence.
Stages of pet seizures:
1 Prodome – preceding a seizure (hours to days) a pet’s mood/behavior might begin subtly changing from its normal essence.
2 Pre-ictal phase – marks the beginning stages of the seizure and can include constant salivation, nervousness, trembling, or whining. It can last seconds to hours.
3 Ictal phase – the actual seizure. Most last from a few seconds to a few minutes and are characterized by tensed muscles and partial paralysis. Some pets lose control of their salivary glands and bowels.
4 Post-ictal Phase – the post-seizure period in which the dog is still disoriented, confused, and possibly dehydrated or salivating. Some pets also experience temporary blindness and wander aimlessly.
Treatment options for pets with seizures
Once a thorough neurological examination has been completed (accompanied by necessary blood tests) and epilepsy has been diagnosed, it is typically controlled with medication. The veterinarian will decide which medication is best for your pet based on their species and breed. In more severe cases epilepsy can be treated with surgery, but surgical options will be determined by the veterinarian for those particular cases. Surgery required advanced diagnostics (such as MRI) at a board certified veterinary neurologist.
If you think your pet may have had a seizure, please contact our office immediately so we can complete a full evaluation to ensure there are no pressing health issues that require emergency medical attention. It is important to remember that epilepsy treatment is not curative and is only meant to help prevent seizures from occurring; though a pet can relapse, and they can still occur. If your pet is placed on anti-seizure medication, he will likely have to remain on the medication for life.
If you think your pet may have epilepsy or have questions about the disease, please contact our office.
