115 Possible Causes for Chronic Denervation (EMG)

Did you mean: Chronic Denervation (EMG, )

  • Infantile Neuroaxonal Dystrophy

    Electromyographic (EMG) signs of chronic denervation, fast rhythms on EEG and abnormal visual evoked potentials were observed in all patients during the disease course.[] : chronic denervation signs 0003444 Emotional lability Emotional instability 0000712 Feeding difficulties Feeding problems Poor feeding [ more ] 0011968 Frontal bossing 0002007[] Dysdiadochokinesis 0002075 Dysmetria Lack of coordination of movement 0001310 Dysphagia Poor swallowing Swallowing difficulties Swallowing difficulty [ more ] 0002015 Dystonia 0001332 EMG[]

  • Spinal Muscular Atrophy Type 3

    Spinal musular atrophies are a group of genetic disorders distinguished by progressive degeneration of anterior horn cells in the spinal cord. Proximal weakness of the extremities that may require use of assistive devices and minimal respiratory difficulties appearing between 18 months and 30 years of age are[…][]

  • Spinal and Bulbar Muscular Atrophy

    Needle EMG revealed a chronic partial denervation with reduced interference in hand and distal leg muscles but with normal heading in all tested proximal muscles.[]

  • Dravet Syndrome

    Nerve conduction study was normal or nearly normal in all patients, but EMG showed features of chronic denervation.[]

  • Ocular Palsy

    EMG revealed siens of chronic denervation and reinnervation in ail four patients; two had synkineiis.[]

  • Abetalipoproteinemia

    Motor conduction was normal, although EMG indicated subclinical signs of partial chronic denervation.[]

  • Myelitis

    Repeat EMG/NCS was performed on 4 children a median of 8 months after onset and showed ongoing denervation and chronic reinnervation in 3 children with persistent deficits[] EMG changes correlated with persistent deficits better than imaging. Despite improvements, AFM had substantial long-term functional effects on affected children.[]

  • Distal Hereditary Motor Neuropathy

    Concentric needle EMG showed evidence of chronic denervation in distal muscles.[] ., most individuals lose some motor neurons after age 55 years) superimposed on chronically denervated muscles.[] Patients with PPS and worsening symptoms often are referred to the EMG laboratory to exclude a new, superimposed process, such as radiculopathy, entrapment neuropathy, myopathy[]

  • Primary Lateral Sclerosis

    Patients with PLS demonstrated no evidence of acute or chronic denervation on EMG/NCS.[] Chronic reinnervation was observed in EMG in 12 patients and in muscle biopsies in 11 patients.[] One had leg weakness as the initial symptom, and 11 years later his EMG/NCS demonstrated acute and chronic denervation.[]

  • Frontotemporal Dementia with Amyotrophic Lateral Sclerosis

    denervation changes on needle EMG.[] […] diagnosed with ALS. 5 ALS is diagnosed by clinical criteria (see El Escorial World Federation of Neurology criteria) and is supported by the presence of generalized active and chronic[]
