313 Possible Causes for Upper Limb Ataxia

  • Spinocerebellar Ataxia Type 20

    Mild or moderate cerebellar ataxia was present in the upper and lower limbs, with all affected patients showing signs of dysmetria, overshoot on ballistic tracking movements[jnnp.bmj.com] Table 1 Clinical observations in six members of the Australian SCA 14 family Examination revealed cerebellar ataxia with abnormal eye movements and brisk reflexes.[jnnp.bmj.com]

  • Vitamin B12 Deficiency

    Neurological examination revealed a sensory ataxia with pseudoathetosis in the upper limbs and reduced vibration sensation to the hips bilaterally.[ncbi.nlm.nih.gov] A 36-year-old man presented to hospital with a 5-week history of ascending limb paraesthesiae and balance difficulties.[ncbi.nlm.nih.gov]

  • Peripheral Neuropathy

    limb, that is, the arm and hand Related signs and symptoms include weakness, changes in sensation over the affected region, absence of reflexes, impaired gait and equilibrium[news-medical.net] […] with ataxia due to impaired proprioception It is associated with impaired conduction velocity within the nerve fibers Causes Peripheral neuropathy occurs in various conditions[news-medical.net] […] associated with peripheral neuropathy has the following characteristics: It is a kinetic or postural tremor It has a frequency of 3-6 Hz occurring primarily in the muscles of the upper[news-medical.net]

  • Primary Progressive Multiple Sclerosis

  • Cervical Osteoarthritis

    Myelopathy causes clumsiness of the hands or gait disturbance, or both, as a result of sensory ataxia or spastic paraparesis of the lower limbs, with bladder dysfunction being[ncbi.nlm.nih.gov] Examination of the upper limbs may show an increase in tone, with a pronator “catch” (C6/C7) or increased tone in finger flexors (C8).[ncbi.nlm.nih.gov]

  • X-linked Parkinsonism-Spasticity Syndrome

    […] symptoms, mild ataxia in the upper limbs, and mild distal muscle wasting. 9 15-18 This more inclusive approach seems to be validated by the multisystem involvement suggested[jnnp.bmj.com] Other features which some authors have included under the umbrella of pure HSP include: mild sensory abnormalities in the lower limbs, absent ankle jerks, pes cavus, urinary[jnnp.bmj.com]

  • Cervical Spondylosis

    Myelopathy causes clumsiness of the hands or gait disturbance, or both, as a result of sensory ataxia or spastic paraparesis of the lower limbs, with bladder dysfunction being[ncbi.nlm.nih.gov] Examination of the upper limbs may show an increase in tone, with a pronator “catch” (C6/C7) or increased tone in finger flexors (C8).[ncbi.nlm.nih.gov]

  • Subclavian Steal Syndrome

    Symptoms may develop during exercise of the upper limbs, when blood is deviated from the vertebrobasilar system to the upper limb.[scielo.br] On exercising the upper limb on the affected side, the patient may experience any of the following: Vertigo.[patient.info] When compensation does not occur, patients may present symptoms related to vertebrobasilar insufficiency: light-headedness, dizziness, vertigo, ataxia, visual disturbances[scielo.br]

  • Benign Adult Familial Myoclonic Epilepsy

    Gait and upper limb ataxia may be accompanied by dysarthria, nystagmus, vertigo, nausea and headache.[epilepsydiagnosis.org] All of the subjects exhibited cortical myoclonus and tremors in the upper limbs.[dovepress.com] EA2 is characterised by periods of cerebellar ataxia lasting minutes to hours, which are triggered by physical and emotional stress.[epilepsydiagnosis.org]

  • Alcoholic Cerebellar Degeneration

    Dysarthria and upper limb ataxia are rare. 4 Pathophysiology Ataxia may develop during periods of abstinence.[slideplayer.com] […] of the lower limbs, ataxia of gait, and trunk instability.[jnnp.bmj.com] […] unsteadiness in walking evolving over months and years. 3 Clinical Syndrome The cerebellar syndrome predominantly affects stance, eye movements, and gait, sometimes with trunkal ataxia[slideplayer.com]
