“…Most polyneuropathies in cats have been reported to involve both sensory and motor components . However, in‐depth electrophysiologic studies for the evaluation of both components are often lacking . Neuropathy associated with type 2 diabetes mellitus is predominantly sensory, but both sensory and motor components are affected .…”

BackgroundReports of motor polyneuropathies in young cats are scarce. Further, in‐depth electrophysiologic evaluation to confirm a motor polyneuropathy in young cats of various breeds other than 2 Bengal cats is lacking.Hypothesis/ObjectivesTo confirm a motor polyneuropathy in young cats of various breeds.AnimalsFive young cats with heterogenous chronic or relapsing episodes of weakness.MethodsRetrospective case series. Cats were presented for evaluation of generalized neuromuscular disease and underwent electrophysiologic examination including electromyography, nerve conduction, and repetitive nerve stimulation. Minimum database and muscle and nerve biopsy analyses were carried out. Descriptive statistics were performed.ResultsDisease onset was at 3 months to 1 year of age and in 5 breeds. The most common clinical sign (5 of 5 cats) was weakness. Additional neurologic deficits consisted of palmigrade and plantigrade posture (4/4), low carriage of the head and tail (4/4), and variable segmental reflex deficits (5/5). Motor nerve conduction studies were abnormal for the ulnar (4/4), peroneal (5/5), and tibial (2/2) nerves (increased latencies, reduced amplitudes, slow velocities). A marked decrement was observed on repetitive nerve stimulation of the peroneal nerve in 3 cats for which autoimmune myasthenia gravis was ruled out. All sensory nerve conduction studies were normal. Histologic evaluation of muscle and nerve biopsies supported heterogenous alterations consistent with motor polyneuropathy with distal nerve fiber loss.Conclusions and Clinical ImportanceHeterogenous motor polyneuropathies should be considered in young cats of any breed and sex that are presented with relapsing or progressive generalized neuromuscular disease.

Case Description—A 2-year-old spayed female domestic shorthair cat was examined because of bilateral thoracic limb weakness of acute onset. Clinical Findings—Clinical signs included muscle atrophy, paresis, depressed spinal reflexes, hyperesthesia of the thoracic limbs, and reduced jaw muscle tone. Pelvic limb reflexes were normal. Results of a neurologic examination were suggestive of multifocal lesions involving both brachial plexuses and the trigeminal nerves. Abnormal nerve conduction across the brachial plexus and delayed late potentials were found on electrodiagnostic testing, and diffuse subclinical involvement of other regions of the peripheral nervous system was confirmed on the basis of abnormal electromyographic findings for the masticatory muscles and conduction block of the peroneal nerve. Treatment and Outcome—No specific treatments were given, and neurologic signs resolved within a month. A relapse occurred 2 months after the first episode, with clinical signs affecting both the pelvic and the thoracic limbs on this occasion. Again, the condition resolved without specific treatment, and 13 months after the initial episode, the cat reportedly was normal. Conclusions and Clinical Relevance—Findings suggested that brachial plexus neuropathy can be a multifocal disease in cats, even if clinically apparent neurologic deficits are initially subtle or absent, and that electrodiagnostic techniques can be used to identify subclinical involvement of the peripheral nerves.

“…Some cats (2 of 9) in one of the studies developed respiratory paralysis that led to euthanasia, whereas the others recovered uneventfully in 4 to 6 weeks. 36 This author has seen 2 cats with rapidly progressive, flaccid nonambulatory tetraparesis following vaccination against rabies. In both cases, recovery was complete in 2 to 4 weeks after the onset of signs.…”

“…2 Acute onset of areflexic flaccid tetraparesis or tetraplegia similar to AIP in dogs and GBS in people has been described in cats. 35,36 The age of onset varied from 3 months to 4 years of age. Affected cats developed a rapidly ascending flaccid tetraparesis with severely decreased to absent spinal reflexes within 72 hours from the onset of clinical signs.…”
