![]() Idiopathic vestibular syndrome generally develops suddenly with no known cause and most often affects older dogs-thus its alternate name, “old dog vestibular disease.” Like a severe case of vertigo, vestibular disease causes nausea, vomiting, nystagmus, head tilt, stumbling, and falling to the side. Idiopathic vestibular syndrome - The vestibular system is located in the inner ear and controls balance and coordination.The following neurologic conditions are commonly seen in dogs: If you notice any of these problems in your dog, contact your family veterinarian immediately. Nystagmus (i.e., a rapid, back-and-forth motion of the eyes).Pupillary changes, such as excessively dilated or constricted pupils, or different-sized pupils.Neurologic signs can develop after a traumatic event that causes nervous system damage, or may appear suddenly when an underlying neurologic problem progresses to the point of finally causing visible symptoms. Familiarity with common neurologic problems and signs can help you recognize potential problems with your dog’s nervous system. Neurologic conditions can cause problems you may expect, such as weakness, paralysis, and seizures, but may also have effects that seem unrelated, such as vomiting or dilated pupils. ![]() Like lines of communication throughout a building, if your dog develops a problem with his brain, spinal cord, or a nerve, his entire body can be affected. I was told that sometimes that has something to do with head trauma.Your dog’s neurologic system is like an intricate network of wires that leads to the main control center-his brain. My nuero asked my husband at my last appointment if my pupils dialated during one of my sz's so that must have something to do with them.This epilepsy this is so strange.I have done so much research and I still can't figure it out and especially why I was diagnosed at 28 years old? One thing though that I always thought was odd about me is that one of my pupils is usually larger than my other one. During and after the last complex parital that I had, my husband noticed that my pupils were REALLY LARGE. I wonder if my mom dropped me on my head as a baby and just never told anyone! Lol! Maybe that could explain some things? :) I was told that sometimes that has something to do with head trauma. I get alot of negative stigma from staring eyes whenever I have one. I've never had a seizure shrink them though.Īnd to answer another question, yes, there are people who's eyes are perfect fine during seizures, my friend in particular who has Grand Mal seizures never has eye changes during them.īut yes, from my experience, it's very problematic having pupil changes during a seizure. Maybe it's where in the brain the seizures occur, that's my best guess. ![]() Of course during those seizures I do bizarre things, so it's common for people to think i'm on drugs, even though i'm not on anything (other than medications, of course). Now, this doesn't happen when I have Absence seizures, but it does during Partial/Complex ones. In cases where panic attacks happen because of the sz, then it is definitely the SNS that is the culprit, because a panic attack is basically a heightened fight-or-flight response, in absence of a ''''''real danger'''''' (not the ''''''_''''''' I put around it because the person feeling it would definitely feel like there's real danger) and the SNS goes into overdrive then.įor me, my pupils become massive during, and sometimes a little before/after a seizure. It's like a storm in a teacup.Įxtrapolating from this, I would guess that activates the SNS in some way. My BEST educated guess is during a sz, the brain goes into overdrive, and the neurons are firing randomly and also over-firing uncontrollably, at a very fast pace. Pupillary dilation is another sign of SNS activation. During the activation of the SNS (for people with no sz), physiological responses such as heart rate increases, there is increase in sweating, trembling, dry mouth etc-think how you would feel if you suddenly had to give a speech in front of 1000 people, or were suddenly told you won the lottery. The SNS is the body's fight-or-flight system and prepares you if you need to flee, fight, run, etc. My best guess would be that during a seizure, and subsequent panic attack that follows, the Sympathetic Nervous System (SNS) is activated.
