Clinical Information

• Lyme Neuroborreliosis-. nervous system infections caused by tick-borne spirochetes of the borrelia burgdorferi group. the disease may affect elements of the central or peripheral nervous system in isolation or in combination. common clinical manifestations include a lymphocytic meningitis, cranial neuropathy (most often a facial neuropathy), polyradiculopathy, and a mild loss of memory and other cognitive functions. less often more extensive inflammation involving the central nervous system (encephalomyelitis) may occur. in the peripheral nervous system, b. burgdorferi infection is associated with mononeuritis multiplex and polyradiculoneuritis. (from j neurol sci 1998 jan 8;153(2):182-91)
• Polyradiculopathy-. disease or injury involving multiple spinal nerve roots. polyradiculitis refers to inflammation of multiple spinal nerve roots.
• Spinal Nerve Roots-. paired bundles of nerve fibers entering and leaving the spinal cord at each segment. the dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. the dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots are efferent, comprising the axons of spinal motor and preganglionic autonomic fibers.
• Alcoholic Polyneuropathy-. any disease affecting more than one nerve.
• Chronic Inflammatory Demyelinating Polyneuropathy|CIDP|Chronic Inflammatory Demyelinating Polyneuritis|Chronic Inflammatory Demyelinating Polyradiculoneuropathy-. an immunologic inflammatory disorder characterized by loss of myelin in the peripheral nerves. patients present with progressive weakness and loss of sensory function in the legs and arms.
• Chronic Polyneuropathy-. polyneuropathy that is persistent or long-standing in nature.
• Demyelinating Polyneuropathy-. polyneuropathy that is characterized by demyelination of axons.
• Familial Amyloid Neuropathy|Amyloid Neuropathies, Familial|Familial Amyloid Polyneuropathy-. a rare inherited neuropathy characterized by deposition of amyloid in the peripheral nerves.
• Paraneoplastic Polyneuropathy-. a diffuse or multifocal peripheral neuropathy caused by the effects of a distant neoplasm. it may be attributed, in part, to the immune response to neoplasm-elaborated proteins. the neuropathy may be sensory, motor, mixed or autonomic. it may be the initial presentation of an occult neoplasm. detection and resection of the neoplasm may result in cure.
• Polyneuropathy-. a disease or disorder affecting more than one nerve.
• Toxic Polyneuropathy-. polyneuropathy that is caused by exposure to toxins.
• Congenital Facial Nerve Palsy-. partial or complete paralysis of the facial muscles of one side of an individual's face that is present at birth. it is caused by damage to the seventh cranial nerve.
• Acute Motor and Sensory Axonal Neuropathy|Acute Motor And Sensory Axonal Neuropathy|Acute Motor-Sensory Axonal Neuropathy|Acute Motor-Sensory Axonal Neuropathy-. a subtype of guillain-barre syndrome that targets sensory motor axons, and is characterized by acute onset of quadriparesis, distal sensory loss, areflexia, and respiratory insufficiency.
• Acute Motor Axonal Neuropathy|AMAN-. a subtype of guillain-barre syndrome that targets motor axons, and is characterized by symmetric limb weakness, diffuse areflexia, facial and oropharyngeal muscle weakness, and respiratory insufficiency.
• Axonal Neuropathy-. any nerve disorder affecting the axon of a nerve.
• GAN wt Allele|GAN1|Giant Axonal Neuropathy (Gigaxonin) Gene|Gigaxonin wt Allele|KLHL16-. human gan wild-type allele is located in the vicinity of 16q24.1 and is approximately 65 kb in length. this allele, which encodes gigaxonin protein, is involved in both ubiquitination and neurofilament structure. mutation of the gene is associated with giant axonal neuropathy.
• Giant Axonal Neuropathy-. a rare inherited disorder affecting the neurofilaments. it is caused by mutations in the gan gene. it is characterized by the presence of abnormally large nerve cell axons. signs and symptoms include difficulty walking, sensory disturbances, lack of motor coordination and abnormal reflexes in the limbs.
• Spinocerebellar Ataxia, Autosomal Recessive, with Axonal Neuropathy 2|AOA2|Ataxia with Oculomotor Apraxia Type 2|SCAN2-. an autosomal recessive condition caused by mutation(s) in the setx gene, encoding probable helicase senataxin. it is characterized by juvenile onset progressive cerebellar ataxia, axonal sensorimotor peripheral neuropathy, and increased concentrations of serum alpha-fetoprotein. oculomotor apraxia is common, but is not always present.
• Acute Inflammatory Demyelinating Polyradiculoneuropathy|AIDP|Acute Inflammatory Demyelinating Polyradiculopathy|Acute Inflammatory Demyelinating Polyradiculopathy-. a subtype of guillain-barre syndrome that targets the myelin sheath, and is characterized by progressive weakness, distal paresthesia and autonomic dysfunction.
• Polyradiculopathy-. a radiculopathy that is present in more than one nerve.

Peripheral Nerve Disorders

Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body.

There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders.

Symptoms often start gradually, and then get worse. They include :

• Numbness
• Pain
• Burning or tingling
• Muscle weakness
• Sensitivity to touch

Treatment aims to treat any underlying problem, reduce pain and control symptoms.
