The diagnosis of<unk>  is based on signalment and medical history. It is considered a diagnosis of exclusion, meaning other possible causes must be investigated and ruled out before diagnosing<unk>  head<unk> s. Differential diagnoses include primary neurologic diseases like cerebellar disorders, steroid-responsive<unk>  syndrome ("little white shaker syndrome"), and exposure to toxins. Endocrine/metabolic diseases like hepatic encephalopathy and infectious diseases like rabies and canine distemper must also be ruled out. The first step is a comprehensive physical examination, including obtaining vital signs, auscultation of the heart, and palpation of the head, neck, and limbs. Additional testing includes a bile acid test, eye exam, brain MRI, and cerebrospinal fluid (CSF) analysis. These tests will enable the veterinarian to rule out the cause as an eye or progressive central nervous system problem.<unk>  with<unk>  head<unk> s have no other neurological abnormalities, and both MRI and cerebrospinal fluid analyses produce normal results.
