  • ataxia: disorder of standing, walking and maintaining balance;
  • asynergy: disorder of coordination of distant muscle groups;
  • dysmetria: goal pursuit;
  • adiadochokinesia: inability to perform rapid alternating movements, eg supination/pronation;
  • intention tremor : shaking during targeted movements (as opposed to resting tremor);
  • muscle hypotonia: passivity.

Paleocerebellar syndrome[edit | edit source]

Disorder of the central parts of the cerebellum

  • affects axial and proximal limb muscles;
  • disorders of standing, walking, balance; asynergy.

Neocerebellar syndrome[edit | edit source]

Disorder of the lateral parts (hemispheres) of the cerebellum

  • affects the distal muscles of the limbs and fine motor skills;
  • dysmetria, hypotonia, adiadochokinesia, intention tremor.
