401 Possible Causes for Slow Nerve Conduction Velocities

  • Uremic Neuropathy

    Case 58A A Woman with Leg Numbness Pain Weakness and Slow Nerve Conduction Velocities 372 Case 58B A Boy with Leg Weakness 375 Case 59 A Man with Hand Weakness and Numbness[]  Motor nerve conduction velocity - often measured in peroneal nerve - often measured in peroneal nerve - slowing of nerve conduction velocity - slowing of nerve conduction[] Early studies of uremic neuropathy measured nerve conduction velocities and found them to be decreased, even in patients without clinical symptoms.[]

  • Hypertrophic Interstitial Neuropathy

    Electromyography showed motor nerve and sensory nerve conduction velocity was slowed down.[] nerve conduction velocities ( Many phenotypic variants have been reported.[] Nerve conduction velocities are slow, and distal latencies are prolonged. Segmental demyelination and remyelination occur. Enlarged peripheral nerves may be palpated.[]

  • Charcot Marie Tooth Disease

    HMSN1 is the most common form of hereditary neuropathy, characterized by severely and uniformly slowed nerve conduction velocities and primary hypertrophic myelin pathology[] The EMG and NCV were consistent with demyelination and slow nerve conduction velocities.[] Electrophysiological studies distinguish two major types – the demyelinating form, which is characterized by symmetrically slowed nerve conduction velocity (NCV; usually 1[]

  • Guillain-Barré Syndrome

    Nerve conduction analysis will reveal slow nerve conduction velocities due to the damage to the nerve.[] conduction studies slowed conduction velocity reduced amplitude in compound muscle action potentials reduced amplitude with relatively preserved conduction velocity implicates[] […] axonal neuropathy delayed/absent F waves implicates nerve root involvement delayed/absent H reflex correlates with decreased/absent ankle reflex MRI cauda equina gandolinium[]

  • Ulnar Nerve Entrapment

    An electromyographic (EMG) investigation revealed slowing of the motor conduction velocity in the ulnar nerve across the elbow.[] The most reliable finding is slowing of the ulnar across-elbow motor nerve conduction velocity to less than 50 m/sec while recording from the abductor digiti minimi muscle[] Examining the electrical activity may help a physician study any injury to the ulnar nerve within the elbow Nerve conduction velocity (NCV) of ulnar nerve: Nerve conduction[]

  • Hereditary Sensory Neuropathy

    […] be distinguished from each other by the typical findings in nerve conduction velocities (marked slowing of motor nerve conduction velocity uniformly in all peripheral nerves[] Motor nerve conduction velocities are mildly slowed and motor action potentials are reduced in advanced cases.[] […] in type I, near normal velocities in type II and profound slowing in the order of 5-10 m/s in type III HMSN).[]

  • Demyelinating Disease

    This will give a falsely slow conduction velocity.[] - Nerve conduction velocity slowed because of multifocal destruction of myelin segments involving many axons within a peripheral nerve What abnormalities would you see in[] Using this hypothesis in segmental demyelinating disease, latency alone is a better parameter of nerve conductivity than nerve conduction velocity, and serial latencies may[]

  • Peroneal Nerve Compression Neuropathy

    Slowing of peroneal nerve conduction velocities at the fibula head may or may not be detected.[] There was a focal slowing of the maximum nerve condition velocity across the neck of the fibula.[] Amplitudes can also be compared with the contralateral unaffected peroneal nerve or if necessary to normal control values.[]

  • Chronic Inflammatory Demyelinating Polyneuropathy

    Although the patient noticed little muscle weakness, an electrophysiological study demonstrated slow conduction velocities and prolonged distal latencies, with definite conduction[] Young age at onset, duration of symptoms less than 6 months, slight neurologic impairment, and mild slowing of nerve conduction velocities have been associated with a favorable[] Electrodiagnostic studies show evidence of demyelination with slowed conduction velocities, prolonged distal latencies, temporal dispersion of compound muscle action potential[]

  • Carpal Tunnel Syndrome

    Median nerve conduction velocities are slowed along the wrists and hands of people with CTS.[] Picture of carpal tunnel syndrome The diagnosis is strongly suggested when a nerve conduction velocity test is abnormal.[] Ultrasound and MRI are useful adjunctive tests to gather additional information if the nerve conduction test is equivocal or negative and a high degree of suspicion exists[]
