Flashcards in Rapidfire 3 Deck (25):
1

decerebrate

midbrain is lesioned, arms extended

2

decorticate

red nucleus is intact, arms flex (bring to core)

3

medullary lesions

no eye findings, have abnormal gags

4

dilated unilateral pupil

usually compression of III, herniation (uncal)

5

cheyne-stokes breathing (location)

bilateral hemispheres or bilateral thalami

6

ataxic breathing or apnea

lesion in medulla

7

hyperventilation

lesion in the midbrain

8

MCA stroke symptoms

face and arm weakness greater than leg weakness

9

ACA stroke symptoms

damage to leg homunculus- leg weakness
ipsilateral gaze deviation, intact VOR

10

PCA stroke symptoms

visual loss on opposite side
alexia without agraphia (problems reading, intact writing)

11

L MCA stroke symptom

aphasia

12

R MCA stroke symptoms

neglect, spatial disorientation, homonymous hemianopsia

13

basilar artery supplies

pons and midbrain

14

vertebral arteries supply the

medulla

15

subdural hematoma

crosses suture lines
venous bleed, very slow

16

epidural hematoma

usually due to trauma
middle meningieal arteries

17

fixed dilated pupil, contralateral weakness

uncal herniation

18

weakness in contralateral leg

subfalcine herniation

19

central herniation symptoms

pushes on brainstem, loss of consciousness and death

20

tonsilar herniation symptoms

affects medulla, results in breathing problems

21

intraparenchymal hemorrhage

focal symptoms
VERY high BP and loss of consciousness
usually occurs deep in the brain

22

AVM features

not super high BP, closer to the skull, abnormal vascular lesion

23

amyloid angiopathy

micro bleeds + a more focal bleed
vascular cause

24

thunderclap headache, non-focal symptoms

subarachnoid hemorrhage until proven otherwise

25

dull headache, hypercoagulable state

venous sinus thrombosis
