Status epilepticus, or epilepsy, is a neurological condition that results in recurrent seizures in dogs.
There are several different types of seizures or epilepsy that can affect dogs.
The more seizures a dog has, the more likely there is to be damage among the neurons in the brain, and the more likely the animal is to seize again. Researchers generally classify all seizures as focal seizures, generalized seizures, and focal seizures with secondary generalization.
A focal seizure will affect only a small part of the brain. Generalized seizures tend to affect both sides of the brain.
Signs of an impending seizure may include a period of warning, where a patient will experience what is called an aura. During this time a dog may appear worried, stressed, or frightened. It may experience visual disturbances or seek help from its owner. The dog may experience contractions in its limbs or in its muscles, and may have difficulty controlling urination and bowel movements.
The dog may also experience an altered mental status before progressing to a seizure, as well as develop other neurological symptoms.
Many different factors, including the pattern of seizures, can influence the development of future seizures. For example, how old a dog is when it first develops a seizure may determine the likelihood that it will develop future seizures, reoccurring seizures, and the frequency and outcome of those seizures.
Physical symptoms may include tachycardia, muscle contractions, difficulty with breathing, low blood pressure, weak pulse, fainting, swelling in the brain, and obvious seizures. Some dogs will exhibit mental behaviors that are out of the ordinary, including symptoms of obsessive and compulsive behaviors. Some will demonstrate shaking and twitching. Others may tremble. Still others may die.
Laboratory and biochemical tests may reveal the following:
A medical condition in which the patient has an abnormally fast heartbeat
An involuntary action in which the muscles contract; caused by a problem with the brain.
A condition of frequent or recurring seizures that are not of a system origin
The amount of pressure applied by the blood on the arteries.
Relating to a disease of unknown origin, which may or may not have arisen spontaneously
