EPILEPSY
Two of the cases reported have been confirmed after consultation with a specialist.
Epilepsy is divided into two basic categories: primary and secondary.
Primary epilepsy is also called idiopathic, genetic or inherited.
Between seizures all examinations - physical, neurological, or
diagnostic tests such as EEG - are normal, hence, if no other
explanation can be given for the seizure(s), primary epilepsy is accepted
as the diagnosis.
Secondary epilepsy is acquired due to trauma, infection (encephalitis)
neoplasms, or ischemia (deficiency of blood such as Portosystemic
Shunt), hence a circulatory problem. This is obviously not genetic, with
the exception of PSS. The various causes can all be readily attested.
Many other breeds have a problem with inherited epilepsy. Beagles,
German Shepherds and Keeshonds are some, so it behoves Cairn
breeders to see a consultant with any young Cairn which starts having
seizures - usual age between 1 to 2 years.
Certain syndromes can be regarded as suspicious of low-grade epilepsy
eg "Rage" syndrome, sudden snapping often at imaginary objects,
dilated pupils, aggression towards certain people or animals, inability to
play without becoming hyperactive.
Such animals should not be bred from however good they look.
