Cerebellum

1) Functions 

The cerebellum helps in planning, monitoring, and correction of motor movement using sensory feedback. It coordinates fine motor activity, monitors head and body positions, and participates in learning of new motor skills. 

2) How to Test the Cerebellum

• Finger to nose test
• Diadocokinesia test (pa-ta-ka)
• Uncoordinated, sloppy movement may indicate cerebellar damage

3) Cerebellar Damage Symptoms  

A) Ataxia: discoordinated, clumsy movements 

B) Dysmetria: over or undershooting touching a mark 

C) Dysdiadochokinesia: inability to perform rapid, alternating movements of hand or mouth 

D) Nystagmus: fast, involuntary eye movements either side to side or up and down

E) Ataxic Dysarthria: slurred or scanning (broken into syllables) speech

F) Hypotonia: reduced muscle tone and reflexes; muscle tire 

4) Cerebellar Disorders 

A) Cerebellar hemispheres syndrome

B) Vermal syndrome

C) Friedrich's ataxia

D) Cerebellar agenesis
