Epilepsy is the most common medical neurological disorder in dogs. The term epilepsy refers to recurrent seizures resulting from an abnormality in brain function. The condition can be inherited (genetic epilepsy), caused by structural problems in the brain (symptomatic epilepsy), or may be of unknown cause (idiopathic epilepsy). Determination of the appropriate treatment for canine epilepsy, as well as prognosis for the condition, depends on accurate diagnosis of the type and cause of seizures.
