Epilepsy may result from injury to the head or from bacterial
infections of the brain. If no such cause is found, it is regarded to
be congenital. Congenital epilepsy can be an inherited trait, and has
been observed in many breeds. The term epilepsy refers to recurring
episodic seizures/convulsions. The episodes can be triggered by
fatigue, excitement, anxiety, noise or in females, by estrus. It may
be controlled with medication. Obviously, breeding is not recommended.
