Neuro Flashcards
pure motor stroke
internal capsule (affects CONTRA side) "lacunar infarct"
pure sensory stroke
lacunar infarct of the thalamus
anterior cerebellar artery stroke
affects CONTRA LE
can be motor or sensory
middle cerebellar artery stroke
affects CONTRA face and UE
can be motor or sensory
aphasia if dominant side is affected
hemineglect if nondominant side
causes Brocas/ Wernickes
mood findings in LMCA vs RMCA
left - depression
right - mania
Broca’s: where? what artery?
inferior frontal of Left hemisphere
MCA
Wernicke’s: where? what artery ?
superior temporal of Left hemisphere (if R handed - meaning dominant hemi is the L)
MCA
vertibrobasilar a. stroke
affects the brainstem
see “alternate syndrome”: contra motor, ipsa cranial nerve findings
+/- ataxia
essential tremor
aka postural tremor
fine resting tremor, worse with intentional mvmt
better with alcohol
usually genetic
tx: BB, primidone (anticonvulsive agent)
parkinsons tremor
“pill rolling”
improves with intentional mvmt
intention tremor
fine with rest, zigzagging motion starts with pointing, or intending to touch nose, etc
indicates cerebellar dysfunction
Worst headache of my life, worse with sitting improves with laying down
meningitis (sitting causes hip flexion)
tx: ceftriaxone, vanco
add ampicillin if you suspect listeria
L hemiparesis and hemisensory loss What artery?
Also, what visual changes can you have?
MCA
R (contralateral) homonymous hemianopia
remember the optic radiation are in the parietal lobe
Central v. Peripheral Bell’s Palsy
Bells palsy = CN VII lesion
see: decreased lacrimation, hyperacusis, and loss of taste over the anterior 2/3 of the mouth, loss of nasolabial fold.
Central: forehead is spared, able to close the eye on the affected side
