49 Possible Causes for Falling, Mild Cognitive Impairment, Percussion Myotonia

  • Myotonic Dystrophy

    Percussion myotonia or myotonia of grasp or both is usually present if looked for.[pediatrics.aappublications.org] Specifically, the regional distribution and neuropsychologic correlates of NFTs and amyloid plaques in cognitively normal elderly subjects and in persons with mild cognitive[doi.org] […] nine hole peg test (r 0.602*) and (2) measures of disease severity/burden, such as MIRS (r 0.718*), MDHI (r 0.483*), and DM1-Activ (r -0.749*) (*p KEYWORDS: Balance; DM1; Falls[ncbi.nlm.nih.gov]

  • Muscular Dystrophy

    Myotonia (prolonged muscle contraction) occurs spontaneously or is elicited by voluntary activity or by mild stimulation, such as tapping on a muscle (percussion myotonia)[neuropathology-web.org] Symptoms include frequent falling, difficulty in climbing, and a waddling gait.

  • Generalized Myotonia of Thomsen

    On examination he showed percussion myotonia. There was no grip myotonia or eyelid myotonia. Nerve conduction studies were normal.[jnnp.bmj.com] Spasticity, dystonia, tremor and migraine were variably present; cognitive impairment was severe in early childhood cases, but was absent in adults.[jnnp.bmj.com] As with myotonic goats, children are more prone to falling than adults, due to their impulsivity.[liquisearch.com]

  • Paramyotonia Congenita

    They experience neither grip nor percussion myotonia during warm weather, whereas myotonia is provoked by cold. Her younger son has no symptoms.[ncbi.nlm.nih.gov] cognitive impairments 17 ; more severe intellectual disability is more common with younger onset of clinical disease.[now.aapmr.org] Though exercise induced a mild fall in CMAP amplitude in both groups, postexercise fibrillations occurred only in patients with paramyotonia congenita.[ncbi.nlm.nih.gov]

  • Limb-Girdle Muscular Dystrophy Type 1E

    Myotonia (prolonged muscle contraction) occurs spontaneously or is elicited by voluntary activity or by mild stimulation, such as tapping on a muscle (percussion myotonia)[neuropathology-web.org] cognitive impairment LGMD2B DYSF / Dysferlin Young adulthood Very high Slow Asymmetric weakness; preference for biceps with spared deltoid; Absent or reduced dysferlin staining[now.aapmr.org] Fractures and falls Owing to weakness, contractures and poor balance, patients with LGMD1 are at high risk of frequent falls.[mdfgauteng.org]

  • Upper Motor Neuron Disease

    Myotonia is a slowness of relaxation of muscles after a voluntary contraction or a contraction provoked by muscle percussion.[dartmouth.edu] Although most cases of MND show only mild or no cognitive impairment, up to 15% may present with frank frontotemporal dementia, which is then associated with more rapidly[pn.bmj.com] Having to think about taking one step without falling and/or crashing a bone?
