Atonic Seizures in Dogs

Seizures are the most common neurological problem seen in dogs. Seizures are the result of a sudden electrical disturbance in the cells of a dog's brain. It is often impossible to determine the exact cause of seizures; therefore, most seizures are diagnosed as idiopathic epilepsy.

  1. Idiopathic Epilepsy

    • Idiopathic epilepsy is the term used for any seizure activity that has an unknown cause. There are two classifications of idiopathic epileptic seizures: generalized and focal.

    Atonic Seizures

    • Generalized seizures affect the entire area of the brain and involve the muscles on both sides of the body. Atonic seizures are generalized seizures with no known cause; therefore, they are considered idiopathic epileptic seizures.

    Symptoms

    • Atonic seizures are often called "drop attacks." Atonic seizures cause a loss of muscle tone and temporary loss of consciousness causing your dog to fall to the ground

    Duration

    • Atonic seizures happen abruptly and last only a few seconds. Dogs recover quickly after an atonic seizure and usually return to normal within minutes with no lasting effects.

    Treatment

    • If seizure activity occurs on a regular basis, you vet may prescribe an anti-convulsive medication such as phenobarbital. The decision regarding when to begin anti-seizure medication varies among veterinarians.
