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.
