"Introduction
Ataxia: Incoordination of volitional movement. It represents a wide range of overlapping symptoms. The differential diagnosis is wide and includes benign as well as life-threatening diseases.
The effects of cerebellar disease involve
  • Loss of acceleration and deceleration movement
  • Clumsiness managing the rate, range, and force of movement
Pearls
  • Complaints of dizziness, vertigo, weakness, nausea, vomiting, and falling are common.
  • Ataxia is different than pure alterations in gait and must be understood.
  • Central causes of ataxia are most concerning and include multiple sclerosis, vertebrobasilar insufficiency, acoustic neuromas, infections, and intoxications.
  • Posterior circulation strokes can be particularly debilitating and carry a mortality rate of 7-20% even despite intervention
  • The misdiagnosis of posterior fossa infarcts in the Emergency Department is frequent.
  • Non-cerebellar, supratentorial lesions are capable of causing isolated motor ataxia"
