Neuro 34: Cerebellar Disorders

Front 1

list some sxs of cerebellar dysfunction

Back 1

inccordination-appendicular ataxia, dysdiadocokinesia, titubation, impaired supression of VOR, gait imbalance, scanning dysarthria, decreased muscle tone and reflexes

Front 2

List some disorders that must be ruled out when considering cerebellar dysfunction

Back 2

muscle weakness (LMN/UMN problems), vestibular dysfunction, impaired proprioception

Front 3

In general, cerebellar lesions produces sxs on which side

Back 3

ipsilateral to the lesion (note bilateral sxs like trucal ataxia)

Front 4

Titubation (truncal ataxia) is a sxs that localizes to which region of the cerebellum

Back 4

vermis/ flocculonodular lobe

Front 5

Describe the normal function of the vermis in terms of the VOR

Back 5

The vermis supresses the VOR when you are trying to watch of moving object so that you can fixate on it and keep it in focus even if you are moving. Supression allows you eyes to turn with your head instead of turning the opposite direction.

Front 6

What type of cerebellar lesion could lead to impaired supression of the the VOR

Back 6

midline lesions,vermis, floculonodular lobe

Front 7

in which direction will objects be blurred if the right cerebellar hemisphere is damaged

Back 7

Left to right. (the burring occurs when the objects move toward the side of teh lesion
