21 Possible Causes for Aspiration Pneumonia, Cerebellar Ataxia, Compound Muscle Action Potential with Low Amplitude

  • Miller-Fisher Syndrome

    We herein report the case of a 53-year-old man with cerebellar ataxia with anti-glutamic acid decarboxylase antibody (GAD-Ab) who mimicked Miller Fisher syndrome (MFS).[ncbi.nlm.nih.gov] The immediate cause of death was considered to be aspiration pneumonia.[academic.oup.com] CBs resolved, distal compound muscle action potential (CMAP) amplitudes increased and SNAPs normalized on subsequent testing.[ncbi.nlm.nih.gov]

  • Hereditary Motor and Sensory Neuropathy

    ataxia, deafness, and narcolepsy AD 9 19 DST Neuropathy, hereditary sensory and autonomic AR 9 7 DYNC1H1 Spinal muscular atrophy, Charcot-Marie-Tooth disease, Mental retardation[blueprintgenetics.com] Laryngeal dysfunction with aspiration pneumonia.[patient.info] Compound muscle action potentials are either absent or low amplitude with motor conduction velocities ranging from 3 to 10 meters per second.[academlib.com]

  • Guillain-Barré Syndrome

    The ataxia was thought to be cerebellar in origin and areflexia due to mesencephalic and upper pontine reticular formation involvement.[dx.doi.org] Thromboembolism, pneumonia, skin breakdown. Cardiac arrhythmia. Ileus. Aspiration pneumonia. Urinary retention. Psychiatric problems - eg, depression, anxiety.[patient.info] muscle action potentials reduced amplitude with relatively preserved conduction velocity implicates axonal neuropathy delayed/absent F waves implicates nerve root involvement[step2.medbullets.com]

  • Myasthenia Gravis

    Complications Aspiration pneumonia due to throat muscle weakness. Acute respiratory failure during an exacerbation.[patient.info] Distinguishing features of the RNS test in LEMS and MG are confirmed in this direct comparison study: the low compound muscle action potential amplitude, decrement at LRS,[ncbi.nlm.nih.gov] Cerebellar ataxia with anti-glutamic acid decarboxylase antibodies: study of 14 patients. Arch Neurol. 2001;58:225–30.[doi.org]

  • Lambert Eaton Myasthenic Syndrome

    Several reports have presented patients with subacute cerebellar ataxia (CA) and Lambert-Eaton myasthenic syndrome (LEMS).[ncbi.nlm.nih.gov] Approximately 2 months after the operation, he had aspiration pneumonia with respiratory failure.[jmedicalcasereports.biomedcentral.com] Distinguishing features of the RNS test in LEMS and MG are confirmed in this direct comparison study: the low compound muscle action potential amplitude, decrement at LRS,[ncbi.nlm.nih.gov]

  • Autosomal Dominant Hereditary Sensory and Autonomic Neuropathy

    Mutations in exon 20 of this gene leads to hereditary sensory and autonomic neuropathy type IE, and mutations in exon 21 cause autosomal dominant cerebellar ataxia, deafness[ncbi.nlm.nih.gov] Compounding the problem of aspiration pneumonias and chronic lung disease is the presence of relative insensitivity to hypoxemia [ 23 – 26 ], which limits ability to cope[ojrd.biomedcentral.com] Patients have relatively normal nerve conduction velocities but low amplitude sensory nerve action potentials and compound muscle action potentials.[merckmanuals.com]

  • Neuropathy

    Compounding the problem of aspiration pneumonias and chronic lung disease is the presence of relative insensitivity to hypoxemia [ 23 - 26 ], which limits ability to cope[ncbi.nlm.nih.gov] Patients have relatively normal nerve conduction velocities but low amplitude sensory nerve action potentials and compound muscle action potentials.[merckmanuals.com] . : Cerebellar ataxia and coeliac disease. Lancet 2004, 362 :1548.[doi.org]

  • Acute Juvenile Hemorrhagic Cystitis

    ataxia Autosomal dominant cerebellar ataxia type 1 Autosomal dominant cerebellar ataxia type 2 Autosomal dominant cerebellar ataxia type 3 Autosomal dominant cerebellar ataxia[sanfordresearch.org] A high percentage of patients with IBM are affected ( 133 ), which leads to the risk for malnutrition and aspiration pneumonia.[frontiersin.org] - aspiration with granulomatous bronchiolitis and lipoid pneumonia Case 278: 62 year old man with anterior mediastinal mass - atypical carcinoid tumor of thymus Case 266:[pathologyoutlines.com]

  • Distal Hereditary Motor Neuropathy Type 1

    Laryngeal dysfunction with aspiration pneumonia.[patient.info] Compound muscle action potentials are either absent or low amplitude with motor conduction velocities ranging from 3 to 10 meters per second.[academlib.com] ataxia Autosomal dominant cerebellar ataxia type I Autosomal dominant cerebellar ataxia type II Autosomal dominant cerebellar ataxia type III Autosomal dominant cerebellar[se-atlas.de]

  • Infantile Hemiplegia

    One patient with incomplete occlusion of a vertebral artery showed acute cerebellar ataxia.[ncbi.nlm.nih.gov] , which can lead to pneumonia, malnutrition, dehydration, and other complications Enteral feedings (tube feedings) should be initiated within 7 days after stroke for patients[now.aapmr.org] , AH - abductor hallucis muscle, Ampl- amplitude, L- left, R- right Figure 1 - Reduced motor nerves compound muscle action potential and slow conduction velocity with low[smj.org.sa]
