Can CH be officially diagnosed?

Yes, it can, though it’s primarily diagnosed though process of elimination. There is no simple test for CH, though it can be verified through an MRI. It is always best to get a professional diagnosis from a veterinarian familiar with neurological conditions in cats as they can have many causes with most being very severe if not properly diagnosed early.  It is important to keep in mind that CH does NOT progress or get worse, in fact most cats tend to learn to adapt and improve.  If your cat’s symptoms are new or worsening, then it most likely not CH. To rule out many of these other conditions as a cause for your cat’s neurological issues, your vet may recommend to perform some combination of the following tests:

  • CBC
  • Serum Chemistry Profile
  • Urinalysis
  • Abdominal ultrasound
  • Parasitic screening
  • Cerebrospinal fluid (CSF) tap
  • Electroencephalogram (EEG)
  • Electromyograph (EMG)
  • Brainstem Auditory Evoked Response (BAER)
  • CAT scan
