45 Possible Causes for Compound Muscle Action Potential with Low Amplitude, Guillain-Barré Syndrome

  • Neuropathy

    Unfortunately, none of these tests can diagnose Guillain-Barré syndrome.[] Patients have relatively normal nerve conduction velocities but low amplitude sensory nerve action potentials and compound muscle action potentials.[] Anticipating mechanical ventilation in Guillain-Barré syndrome. Arch Neurol. 2001;58(6):893–898. 12. McCarberg BH, Billington R.[]

  • Tick Paralysis

    However, the weakness seen in tick paralysis progresses more quickly than what is generally seen in Guillain-Barré's syndrome and the protein concentration is not elevated[] Neurophysiological studies reveal low-amplitude compound muscle action potentials with normal motor conduction velocities, normal sensory studies and normal response to repetitive[] Clinical and electrodiagnostic findings failed to adequately distinguish tick paralysis from Guillain-Barré syndrome in these patients.[]

  • Guillain-Barré Syndrome

    muscle action potentials reduced amplitude with relatively preserved conduction velocity implicates axonal neuropathy delayed/absent F waves implicates nerve root involvement[] Who gets GuillainBarré syndrome? Anyone, at any age, is susceptible to Guillain- Barré syndrome.[] The severe, generalised manifestation of Guillain-Barré syndrome with respiratory failure affects 20-30% of cases.[]

  • Bickerstaff Brainstem Encephalitis

[9] Mechanism [ edit ] GuillainBarré syndrome – nerve damage The nerve dysfunction in GuillainBarré syndrome is caused by an immune attack on the nerve[] CBs resolved, distal compound muscle action potential (CMAP) amplitudes increased and SNAPs normalized on subsequent testing.[] KEYWORDS: Guillain-Barré syndrome; Miller Fisher syndrome; Pharyngeal–cervical–brachial weakness; Reversible conduction failure[]

  • Neuromuscular Junction Disorder

    […] triggers about 30% of cases of Guillain-Barré syndrome”.[] EMNG showed signs of myopathy and low compound muscle action potential (CMAP) amplitude (0,15 mV) on lower extremities. Muscle and nerve biopsy were normal.[] Particular attention must be paid to compound muscle action potential (CMAP) amplitudes.[]

  • Rabies

    Motor nerve conduction studies showed decreased conduction with dispersion of compound muscle action potential, low amplitude with prolonged distal latency and decreased nerve[] Barré syndrome (GBS), have been reported after rabies vaccine, but this happens so rarely that it is not known whether they are related to the vaccine.[] In the paralytic form of rabies the acute neurological syndrome may present with generalized weakness and quadriparesis, thereby making it difficult to distinguish from GuillainBarré[]

  • Food-Borne Botulism

    Guillain-Barré syndrome. Poisoning. Myasthenia gravis. Bulbar palsy.[] Electrophysiologic tests of such patients show reduced compound muscle action potentials (CMAPs), low amplitudes and short durations of motor unit potentials (MUPs), and mild[] syndrome.[]
