Movement Disorders: Clinical Phenomenology (2nd hour) Flashcards
What are chorea?
Irregular, rapid, random movements that seem to flow from one body part to another.
What is ballism?
A form of chorea with large amplitude, flinging motions. Often of proximal muscles. (recall the woman who was lurching forward with her shoulder)
What is athetosis?
Writhing motion, often slower and distal.
What is dystonia?
Sustained contraction -> twisting / abnormal postures
What is tremor?
rhythmic, oscillatory movements
What are tics?
Intermitted, repeated, semi-voluntary movements. (can often be repressed)
What is myoclonus?
Shock-like, rapid contraction/jerk
Review-ish: Where is essential tremor localized?
the cerebellum (or -ish)
How is a tremor in ET different from a tremor in PD (Parkinson’s)?
PD: rest tremor more pronounced
ET: tremor comes out when trying to move
How will writing be different in PD vs. ET?
PD: micrographia (small handwriting)
ET: large, jagged, messy handwriting
Is PD more often symmetrical or asymmetrical?
More often asymmetrical.
In which disease (that we’ve focused on) will you be mostly likely to see chorea?
Huntington’s
Name 4 non-PD Parkinsonisms.
Multiple systems atrophy, Progressive supranuclear palsy, corticobasal degeneration, Wilson’s disease
Key feature of Multiple systems atrophy?
Autonomic failure, often manifesting as bad orthostatic hypotension
Key features of progressive supranuclear palsy?
opthalmoparesis, “surprised” expression
