  Vitamin B12 deficiency causes sensory ataxia in addition to muscle weakness. Treatment Of all the movement disorders, ataxia is among the most resistant to medical therapy. Clonazepam may help tremor and balance problems. [bcm.edu]

  For example, muscle weakness and decreased endurance could lead to increasing fatigue and poorer movement patterns. There are several assessment tools available to therapists and health care professionals working with patients with ataxia. [en.wikipedia.org]

• Incontinence

  When severe, these kinds of frontal lobe conditions may result in incontinence, which typically occurs without warning. [dartmouth.edu]

• Polyneuropathy

  Neurophysiologic study of the extremities showed a severe sensory axonal polyneuropathy predominating in the lower limbs with an absence of sensory evocated potentials. [elsevier.es]

  Peripheral nervous system involvement in CANVAS was formerly defined as a sensory, motor, axonal or mixed polyneuropathy, 1, 2 albeit it has been identified as a sensory neuronopathy. 3 In this patient, an absence of sensory action potentials in the nerves [cambridge.org]

  Although elderly patients often lose some sensitivity at the toes, the various causes of polyneuropathy or dorsal column damage should be considered if the sensory loss is out of proportion for age. [dartmouth.edu]

  We excluded 4 DBN patients with clinical evidence for polyneuropathy or uni / bilateral vestibulopathy. [journals.plos.org]

  Distal weakness can be caused by disorders that also produce sensory ataxia, such as polyneuropathies and Friedreich ataxia. 3. Paraparesis [neupsykey.com]

• Paresis

  Ataxia and weakness (paresis) are often confused with each other. The main difference between ataxia and paresis is that ataxia affects coordination without affecting strength, while paresis affects only strength. [vin.com]

  These include nystagmus and related ocular oscillations, gaze paresis, and defective saccadic and pursuit movements. [neupsykey.com]

  In Friedreich ataxia, gait unsteadiness begins between ages 5 and 15; it is followed by upper-extremity ataxia, dysarthria, and paresis, particularly of the lower extremities. Mental function often declines. Tremor, if present, is slight. [merckmanuals.com]

  Vertigo must be distinguished from nonvertiginous dizziness, which includes sensations of light-headedness, faintness, or giddiness not associated with an illusion of movement. [accessmedicine.mhmedical.com]

The prognosis varies, but CANVAS is generally considered to be a slowly progressive condition over decades 3. [radiopaedia.org]
