Lateralising Cerebellar Signs

Cerebellar disease is a common condition in the neurological station due to the unfortunate high rates of alcohol related disease and strokes. However, you might also be given a patient with materialising cerebellar signs and it is important that you can idtenify and understand the pathology of these lesions.

Unilateral disease will cause unilateral signs on the ipsilateral side. Vermis lesions (the midline of the cerebellum) will cause ataxia that is either midline or truncal while lesions of the cerebellar hemisphere will cause ataxia of the limb.

Therefore, depending upon the above, the lesion may be unilateral, bilateral, midline, specific to a hemisphere or global (aka pan-cerebellar).

Causes of cerebellar lesions

  • Creutzfeldt-Jakob disease (global);
  • Syphilis (global);
  • Encephalitis (global).
Cerebrovascular accident
  • associated with vertigo and vomiting (unilateral, midline or hemispheric).
  • alcohol induced Wernicke’s encephalopathy with chronic degeneration (global);
  • anti-convulsant medications such as sodium valproate and phenytoin (global);
  • vitamin B12 deficiency (global);
  • hypothyroidism (global).
  • primary tumour (unilateral, bilateral (unlikely) midline or hemispheric);
  • secondary (unilateral, bilateral, midline or hemispheric).
  • multisystem atrophy (global).
  • multiple sclerosis (unilateral, bilateral, midline or hemispheric or even global);
  • Miller-Fisher syndrome (global);
  • parneoplastic (global).
  • Friedreich’s ataxia (global);
  • mitochondrial disease (global).
