  • “ataxia” means “dysarray,” - any unspecified motor clumsiness;
  • clinical presentation of different types of ataxia;
  • cerebellar ataxia, by imbalanced stance and unsteady, broad-based gait;
  • sensory ataxia, relatively rare;
  • vestibular dysfunction, rare syndrome designated as “vestibular” (or “labyrinthine”) ataxia;
  • pathophysiologically, cerebellar ataxia - failure to maintain normal anti-inertia mechanisms;
  • cerebellar ataxic disorders;
  • acute ataxia, typically seen in ischemic (lacunar, cardioembolic);
  • hereditary ataxias, clinically and genetically heterogeneous group of disorders transmitted;
  • ataxic syndromes - management and prognosis determined by primary cause of ataxia
