Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken. The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present.
Eventually, the dog is alternatively flexing and extending each rear leg in a dancing motion. Dancing Doberman disease progresses over a few years to rear leg weakness and muscle atrophy. No treatment is known, but most dogs retain the ability to walk and it is painless. [7] Diabetes neuropathy is more common in cats
LSS exhibits a multifocal distribution, with conduction block serving as the disease's electrophysiological hallmark. Furthermore, there have been reports of pure motor and sensory CIDP variants, with the latter occasionally limited to sensory nerve roots (chronic immune sensory polyradiculopathy).
Additionally, BP control in those with diabetes is helpful, while intravenous immunoglobulin is used for multifocal motor neuropathy. [1] According to Lopate, et al., methylprednisolone is a viable treatment for chronic inflammatory demyelinative polyneuropathy (which can also be treated with intravenous immunoglobulin).
Multifocal motor neuropathy (MMN) with conduction block is closely related to CIDP (chronic inflammatory demyelinating polyneuropathy). Anti-GM1 antibodies are positive in around 80% of cases. MMN will present with asymmetrical motor neuropathy where reflexes are usually preserved (or slightly increased), affecting upper limb more than lower limb.
Instead, a number of other possibilities have to be ruled out, such as multifocal motor neuropathy or spinal muscular atrophy. Tests used in the diagnostic process include MRI, clinical examination, and EMG. EMG tests in patients who do have PMA usually show denervation (neuron death) in most affected body parts, and in some unaffected parts too.

Life expectancy in MS patients is 5 to 10 years lower than unaffected people. [15] MS is an inflammatory demyelinating disease of the central nervous system (CNS) that develops in genetically susceptible individuals after exposure to unknown environmental trigger(s).
