Aloha! You're speaking to Dr. Michael SalkinI'm sorry to hear of this with your rescue. The paralysis on the right side of her face is likely to be a facial nerve paralysis which as an idiopathic (unknown cause) disorder won't cause her ataxia and inability to rise. Facial paralysis can, however, exist concomitantly with disorders of the central nervous system such as neoplasia, encephalitis, trauma, and polyneuropathies. Anaplasmosis can cause ataxia but I would have expected to see lethargy, fever, and lameness slowly developing prior to the advent of ataxia. In addition, no response to doxycycline or tetracycline should preclude the diagnosis of anaplasmosis. A normal CSF tap and blood leads us to consider a polyneuropathy or acute idiopathic polyradiculoneuritis which might be a challenge to clarify. Polyradiculoneuritis can present as acute-onset tetraparesis/tetraplegia in as little as 72 hours. Polyradiculoneuritis is a diagnosis of exclusion. A working clinical diagnosis is based on the typical clincal presentation of an acute-onset lower motor neuron paraparesis/plegia that rapidly progresses to tetraparesis/plegia. I'm sorry that I can't be more specific for you. Her presentation requires advanced testing (electromyography and nerve conduction velocity studies, e.g.) which aren't available readily. Please respond with further questions or concerns if you wish.
