Dysfunction of what part of the brain leads to ataxia?
A. Nuclei
B. Cerebellum
C. Putamen
D. Caudate Nucleus
B. Cerebellum
What is Ataxia?
the loss of control of body movement,.
It may effect the trunk, one limp, one side of the body, or both legs
Related to issues with: vestibular system, cerebellum, proprioception
Describe Ataxia related to the vestibular system.
disequilibrium and unsteadiness
profound vertigo, and vomitting usually caused by drugs or alcohol
if unilateral: menieres disease
Describe Axtia related to the cerebellum.
lesion in the cerebellum can effect either the trunk or limbs
Dysmeteria is the inability for consistent movement
can even impact speech and cause sluring of words
Describe ataxia related to proprioception.
the inability to stand with your eyes closed, causes heavy walking, stumbling in the dark, caused by inflammation, demyelination, vitamin deficiencies, infections, inherited disorders
