905 Possible Causes for Electromyogram Abnormal, EMG Shows Evidence of Reinnervation, Muscle Biopsy Abnormal

  • Motor Neuron Disease

    For patients with MND affecting the LMNs, the EMG will show evidence of: (1) acute denervation, which is ongoing as motor neurons degenerate, and (2) chronic denervation and[en.wikipedia.org] The results of electromyography and muscle biopsy were compatible with ALS. However, supranuclear vertical gaze palsy and slow saccades are seen.[ncbi.nlm.nih.gov] reinnervation of the muscle, as the remaining motor neurons attempt to fill in for lost motor neurons.[en.wikipedia.org]

  • Muscular Dystrophy

    This condition is typically characterized by large and abnormally distributed mitochondria on muscle biopsy, which can distinguish this condition from the other muscle conditions[ncbi.nlm.nih.gov] Under the microscope, the muscle of a positive biopsy generally shows dead tissue and abnormally large muscle fibers.[cedars-sinai.edu] Muscle biopsies from subjects 1 and 3 were severely dystrophic with abnormal immunofluorescence and western blotting indicative of α-dystroglycan hypoglycosylation.[ncbi.nlm.nih.gov]

  • Duchenne Muscular Dystrophy

    Diagnosis of Duchenne Muscular Dystrophy A muscle biopsy (taking a sample of muscle) for dystrophin studies can be done to look for abnormal levels of dystrophin in the muscle[disabled-world.com] […] fibers) For Duchenne and Becker muscular dystrophies, muscle biopsy may show whether dystrophin, a muscle protein, is missing or abnormal, and DNA testing is used to analyze[webmd.com] A muscle biopsy (taking a sample of muscle) for dystrophin studies can be done to look for abnormal levels of dystrophin in the muscle.[genome.gov]

  • Stiff-Person Syndrome

    Previous diagnostic testing, including magnetic resonance imaging, muscle biopsy, and electromyography, showed no specific abnormalities and blood was negative for anti-GAD[redorbit.com] […] that may be causing pinched nerves an electromyogram, which can help your doctor evaluate how well the muscles and nerves are working an ultrasound, which can help your doctor[healthline.com] She walked with an abnormal “tin solider” gait. Findings on magnetic resonance imaging of her brain and spine as well as electromyograms were normal.[doi.org]

    Electromyography was abnormal in all patients. Muscle biopsy in 1 patient demonstrated normal immunostaining for dystrophin.[ncbi.nlm.nih.gov] […] changes in the structure of the muscle cells Tests that stain the muscle sample can be used to visualize any muscle proteins present Electromyogram (EMG): Another diagnostic[dovemed.com] Elevated serum CK Skeletal muscle biopsy showing decreased dystrophin quantity Panel overlap The gene on this panel is also included on our Autism Intellectual Disability[unmc.edu]

    Only about 10% of ALS patients have abnormal nerve conduction study results, but the test can also suggest other diagnoses. A muscle biopsy.[webmd.com]

  • Myopathy

    Clinical presentation, abnormal secretion of the collagen demonstrated in muscle biopsy and the COL6A1 c.1056 3A C mutation justify classification of the presented case as[ncbi.nlm.nih.gov] Electroencephalographic abnormalities have been noted in several patients with the early-onset form of the disease before clinically apparent seizure activity begins.[anesthesiology.pubs.asahq.org] Laing early onset distal myopathy: slow myosin defect with variable abnormalities on muscle biopsy.
