Epilepsy
(Standard / Miniature / Toy)
Primary epilepsy is a brain disorder characterized by recurrent seizures (without a
brain lesion). The brain is structurally normal but not functionally normal. The
exact mechanism is unknown. It is genetic in many breeds but the mode of inheritance
in unknown. Usually starts between 6 month to 5 years with a prevalence between 6
months and 3 years of age. The seizures are generalized (bilateral and symmetrical)
and usually convulsive. Most seizures occur while the animal is resting or asleep,
most occur at night or early morning. The animal may become stiff, chomping his jaw,
salivating profusely, urinating, defecating, vocalizing, and paddling with all four
limbs in varying combinations. Periods of confusion and disorientation follow with
the animal pacing aimlessly, compulsively, and blindly. Recovery may be immediate or
take up to 24 hours. Seizure frequency tends to increase with time if the animal is
left untreated. Epileptics are on life time medication. Antiepileptic treatment
decreases the frequency, severity and length of the seizures. Perfect control is
rarely achieved.

Epilepsy is best prevented by not breeding affected dogs.
