Epilepsy

Canine Epilepsy is a chronic condition characterized by recurrent seizures. Seizures are the result of muscle responses to an abnormal nerve-signal burst from the brain. The cause can be anything that disrupts normal brain circuitry:

Idiopathic Epilepsy, meaning "no known cause", also referred to as Primary Epilepsy, is possibly inherited. Secondary Epilepsy can be caused by:

  • Low blood sugar
  • Low thyroid function
  • Infections causing brain damage
  • Ingestion of toxins
  • Brain tumors, and
  • Vaccinations

Most dogs with Idiopathic Epilepsy suffer their first seizure between the ages of one and five years. A genetic basis for Idiopathic Epilepsy is strongly suspected in several breeds.
