Neuro Cases Part 2 Flashcards
What is a tremor?
an involuntary, rhythmic, oscillatory movement of a body part & is most common movement disorder seen in primary care offices
resting tremor
happens when body is @ rest
arm resting on table & little fingers are moving
enhanced by mental stress or movement of ANOTHER body part
when will a resting tremor diminish?
voluntary movement of that body part
action tremor
postural
isometric
kinetic
postural tremor
maintaining position v gravity
isometric tremor
muscle contraction v rigid stationary object
kinetic trmeor
voluntary movement, includes intention tremor which produced w/ target-directed movement
enhanced physiologic tremor
low amplitude, high frequency @ rest & during activity
enhanced by anxiety, stress & caffeine
essential tremor
most common PATHOLOGICAL tremor
most common in hands & wrists, present w/ different tasks & interferes w/ activities
alcohol can help symptoms
parkinsonism tremor
clinical syndrome
start w/ little tremor & may get Parkinson’s dementia
what can cause Parkinsons?
various medications (block or deplete dopamine)
What is the main presenting feature of Parkinsons?
70% of pts w/ PD have RESTING TREMOR as presenting feature
classic tremor starts as pill-rolling motion of fingers
bradykinesia (difficulty rising from seated position)
cerebellar tremor
low frequency, slow intention or postural tremor
usually caused by MS, brainstem tumor
psychogenic tremor
difficult to differentiate from organic tremor (real tremor)
abrupt onset, spontaneous remission, changing tremor characteristics, may disappear if distracted
History to obtain for tremor
family history of neuro disease
if in older pt w/ gradual onset, likely to be PD or essential
what does sudden onset of tremor mean?
psychogenic, related to meds or toxin exposure, brain tumor
