Epilepsy is a brain disorder in which a person has repeated seizures over time. Seizures are episodes of uncontrolled and abnormal firing of brain cells that may cause changes in attention or behavior. Epilepsy occurs when permanent changes in the brain cause it to be too excitable or irritable. As a result, the brain sends out abnormal signals. This leads to repeated, unpredictable seizures. (A single seizure that does not happen again is not epilepsy.)
There are a number of different causes of seizures. 1  Head trauma which results in brain swelling can cause seizures. 2  Brain tumors are a very common source of seizures in older pets. 3  Bacterial, viral, fungal and parasitic infections can also cause seizures.  Certain immune-mediated diseases can cause seizures.
