Weak hind end, proprioceptive ataxia RH, can't get up, now had a seizure - what am I?
24-year-old WB mare, neck injury in Nov, best friend died in Dec, right dorsal colitis from NSAIDs in mid-Jan, 5 days in clinic, injected neck, been on soaked pelleted diet, Sucrulfate, Succeed, YeaSacc, Ranitidine ever since. On Legend 1x/month. Lay down and couldn't get up last week, vet said hocks and stifles sore. Injected those, started her on Prevacox (with fingers crossed for her colon) last Weds. She went down again today and couldn't get up. No distress, just lay there, tried to get up a few times but hind end just wouldn't cooperate. Took an hour for the vet to arrive so she drank some water and nibbled at the grass while she lay there. Vet got there just in time for a seizure - eyes gone, tongue hanging out, hind legs paddling, totally non-responsive. Seizure stopped, mare jumped up like all was fine. Vet and I totally WTF? Random search equine seizures turned up hypo-phosphatemia which Sucrulfate has been linked to in rare cases. That's my best idea. Anybody else seen this?
I hope a cure will be found soon, because if not, it may be time for euthanasia. A horse that cannot rise is not only stressed by that, but at risk for other problems developing by being down. Good luck, and keep us posted. Cyber hugs in advance if this is Rainbow Bridge time.
RIP Sasha, best dog ever, pictured shortly before she died. 3/17/12, Jenny has crossed Rainbow Bridge; 5/23/2012 Snowy too now.
Neck injury/arthritis affecting the hind end. Not sleeping since having trouble getting up and down, hence narcoleptic type episode. My gelding absolutely looks like he is having a seizure when this happens, but looks amazingly calm/normal when he snaps out of it. Just my best guess...
In my experience, anything that causes seizures in a 24 year old horse is more insidious than a mineral imbalance. I'm sorry you and your girl are going through this and I hope you get to the bottom of the mystery very soon.
