17. Ataxia

  1. Widespread cerebellar lesions cause more or less symmetrical symptomatology, while localized, unilateral cerebellar lesions cause contralateral hemiataxia. (T/F?)
  2. Worsening of symptoms of ataxia when the eyes are shut indicates absence of sensory ataxia. (T/F?)
  3. Romberg’s test is negative in sensory ataxia. (T/F?)
  4. Scanning speech is typically associated with sensory ataxia. (T/F?)
  5. In tandem Romberg’s test patient places his or her feet in heel-to-toe position with one foot  in front of the other. (T/F?)
  6. Intention tremor is associated with cerebellar ataxia. (T/F?)

  1. Unilateral cerebellar lesions cause ipsilateral hemiataxia.
  2. Sensory ataxia is caused by loss of proprioception, and is worsened when proprioception cannot be compensated by visual input.
  3. Romberg’s test is positive in sensory ataxia.
  4. Scanning speech is a symptom of a lesion in the cerebellum.
