138 Possible Causes for Electromyogram Abnormal, Muscle Biopsy Abnormal, No Muscle Weakness

  • 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] It causes progressive weakness in muscles of the face, arms, legs, and around the shoulders and chest.[ninds.nih.gov] Under the microscope, the muscle of a positive biopsy generally shows dead tissue and abnormally large muscle fibers.[cedars-sinai.edu]

  • 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] Occasionally, however, females who carry a DMD gene mutation may have muscle weakness and cramping.[ghr.nlm.nih.gov] […] 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]

  • Becker Muscular Dystrophy

    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] Later symptoms Muscle weakness: Affects the proximal muscles of the limbs mainly.[patient.info]

  • Primary Lateral Sclerosis

    Muscle histology Deltoid muscle biopsies showed no mitochondrial abnormalities or dysfunction (Table 4 ). Muscle biopsies were normal in seven patients.[brain.oxfordjournals.org] Electromyogram ( EMG ). During an EMG , your doctor inserts a needle electrode through your skin into various muscles.[drugs.com] We report the autopsy findings of an 82-year-old woman who exhibited slowly progressive upper motor neuron signs (pseudobulbar palsy, muscle weakness and positive Babinski's[ncbi.nlm.nih.gov]

  • Polymyositis

    Muscle biopsy abnormalities at some time during their disease: i. degeneration and regeneration of muscle fibers ii. necrosis iii. phagocytosis iv. interstitial mononuclear[clinicaltrials.gov] An electromyogram showed abnormal nerve conduction with evidence of active denervation of most of the muscles tested.[nature.com] Some cases of polymyositis have manifestations of muscle weakness in the orbital muscles. Rare cases also have weaknesses in facial and bulbar muscles.[symptoma.com]

  • Dermatomyositis

    Muscle biopsy abnormalities at some time during their disease: i. degeneration and regeneration of muscle fibers ii. necrosis iii. phagocytosis iv. interstitial mononuclear[clinicaltrials.gov] (EMG) which can demonstrate abnormal electrical activity in muscles and help distinguish weakness due to muscle disease from weakness due to nerve problems A nerve conduction[mda.org.au] Symptoms may include: Muscle weakness, stiffness, or soreness Problems swallowing Purple color to the upper eyelids Purple-red skin rash Shortness of breath The muscle weakness[nlm.nih.gov]

  • 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] Muscle weakness regressed and dysphagia disappeared with treatment.[ncbi.nlm.nih.gov]

  • Motor Neuron Disease

    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] […] wasting and weakness, absent reflexes, loss of weight and muscle twitching.[mndnsw.asn.au] Onset was in the second to fourth decade with finger extension weakness, progressing to other distal and sometimes more proximal muscles.[ncbi.nlm.nih.gov]

  • Amyotrophic Lateral Sclerosis

    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] weakness.[ncbi.nlm.nih.gov] Respiratory muscle weakness and failure is a common complication late in the course of disease.[ncbi.nlm.nih.gov]

  • Childhood Dermatomyositis

    The subsequent list, derived from the first survey, comprised MRI abnormalities suggestive of inflammatory myositis; calcinosis; changes on muscle biopsy typical of myositis[doi.org] (EMG) which can demonstrate abnormal electrical activity in muscles and help distinguish weakness due to muscle disease from weakness due to nerve problems X-rays of the[mda.org.au] In a second flare in childhood, she developed proximal muscle weakness and calcinosis cutis. A muscle biopsy was consistent with juvenile dermatomyositis.[ncbi.nlm.nih.gov]
