Q. Idiopathic vestibular disease which has been on and off for 4 months. MRI, CSF, bloods, urine, abdominal ultrascan all negative....?
A. Because the exact cause is often unknown, there is no specific medical or surgical treatment for feline idiopathic vestibular disease. In cases of middle- or inner-ear infection, appropriate antibiotics or anti-fungal medications will be used. In idiopathic vestibular disease, treatments aimed at reducing motion sickness, nausea, and vomiting are used. Many cats will require assistance eating and drinking during the initial stages of the condition.
Idiopathic vestibular disease ordinarily is a short-term, self-resolving condition. It should not continue for months. Since all the tests were negative, I would just continue to manage her symptoms as best you can and get her rechecked regularly with your vet, or consider getting her seen by a veterinary neurologist if you have not already done so. They may not offer any more insight but you will at least know that you have done everything you can and she will get the best care possible.
