Okay not to alarm you, but please make sure that what you are seeing is in fact cluster seizures (where there is a definite recovery between seizures) and status seizures, where there is no recovery but continues seizures.
Status are the most dangerousā¦ they can and do die from them. So getting this under control fast is critical. A side note, I worked in the UTnK Brain Research and Neuropsychology Lab with Dr Joel Lubar on his epilepsy program.
QUOTE:>> The massive muscle activity of the seizures leads to hyperthermia with temperatures as high as 106 degrees Fahrenheit or more, which if sustained, causes irreversible damage to neurons. Hypoxia from inadequate pulmonary ventilation also causes brain damage. Severe lactic acidosis from shock and tissue hypoxia, amplified by excessive muscle activity, probably contributes to neuron deterioration. Death is usually not from brain dysfunction directly, but from overtaxation of cardiopulmonary reserve by the combination of massive continuous exercise, hypoxia, lactic acidosis, shock, and possibly also hyperthermia.<<
Below are notes from Feb with a vet friend regarding another friend's chow. He was having seizures and they could not get control. (he mostly likely, however, had a brain tumor, and due to age and advancing loss of quality of life was put down.)
NOTES:
Hey, yell when you see this:
OK, friends - I guess I posted too soon that xxx was doing so well. He had another seizure this morning about 4:00am. ...talked to the vet again and I think I would at least like to TRY some antiseizure medication. The vet talked about phenobarbitol and something called Zonisamide. She said that usually Zonisamide is given if the phenobarbitol isn't working - but that they have started giving it as the first drug some. It does not have the side effects of phenobarbitol because it isn't metabolized in the liver. But she also said it is a fairly new drug and hasn't been widely used. I also read online about Potassium Bromide.
BR response::::
KBr is a good option and we have been using Kepra with good results too. I have no experience with Zonisamide
Seizures do need to be controlled we have had 3 dogs in the practice in the last year that went into status and cooked themselves.... body temperature skyrockets during the seizure and causes brain damage
Zonisamide is in the same class of drugs as Kepra.....we have used it as a first option but most often along with pheno when the pheno isn't working by itself
Debra Levey
So would you say start with pheno and add kepra if necessary?
BR:
Depends on liver function.... if ALT is normal then that's what we usually do, mostly because it works quickly (KBR & kepra take a little longer to build a "blood level")
If ALT is elevated or borderline then start with kepra or KBR. Milk thistle is a good idea to support liver also<<<
That's all I can give you as I have never had a dog with seizures. But if you don't get things under control in a couple of weeks, you might consider a specialist at a university since there could be other issues causing it. I am assuming your vet already did blood work and ruled out any toxins or medication issues.
had only 1 seizure when she was 10 yrs. old. When I got her at 2 yrs. old, my vet already saw a small growth in her liver and was hypothyroid. When this happened, I knew this was a symptom of something bigger. The growth in her liver started growing larger since her seizure but even though it was benign, it was located in an inoperable area.
