Peripheral Motor Neuropathy

While diagnosis is based on electrodiagnosis and clinical presentation, MRI maybe performed to rule out other etiologies of nerve injury. [neurology.org]

However, Sjögren syndrome sometimes presents with sensory neuropathy or ganglioneuritis. Ribosomal P antibody may be present in these individuals. [questdiagnostics.com]

The potential role of parkin is interesting, as parkin mRNA is present within human peripheral nerve [ 36 ]. [intechopen.com]

Accordingly, peripheral neuropathies may be characterized by their inheritance, clinical patterns or pathologic presentations. [clinicaladvisor.com]

Several disorders can damage peripheral nerves and cause peripheral neuropathy; it is important to differentiate actual neuropathy from other disorders that can have a similar clinical presentation. [aafp.org]

    The muscle fibers in a motor unit respond in an all-or-none fashion to excitation by the motor neuron (both to natural excitation and artificial stimulation, such as electric nerve stimulation). [dartmouth.edu]

    Release of the body’s own pain-reducing chemicals may be dampened, and some nerve cells along the pathway may become excitable and overly active in signaling pain messages. [neuromodulation.com]

  • Dystonia

    These abnormalities are known as Leber plus'' (see this term), and include motor disorders, dystonia, postural tremor and cerebellar ataxia. Etiology LHON is caused by mutations in the mitochondrial DNA (mtDNA). [orpha.net]

    In particular, it was felt that pain was most often related to the presence of concurrent dystonia [ 31 ]. [intechopen.com]

  • Dysarthria

Prognosis The age of symptom onset (younger patients having a more favorable prognosis) and the causative mutation (patients with MT-ND6 mutations showing highest recovery rates) are factors that determine the disease outcome. [orpha.net]

What You Need to Know There are more than 100 types of peripheral neuropathy, each with its own set of symptoms and prognosis. Peripheral neuropathy has many different causes. [hopkinsmedicine.org]

WHAT IS THE PROGNOSIS FOR PERIPHERAL NEUROPATHY? The prognosis for peripheral neuropathy very much depends on the cause and severity of the neuropathy. You would need to speak to your neurologist about your individual case. [precisionhealth.com.au]
