UMN vs LMN lesion

UMN: contralateral paralysis lower face
LMN: ipsilateral paralysis upper and lower face

2

CN XI

Accessory: Head turning, shoulder shrugging

3

CN XII

Hypoglossal: Tongue movement

4

CN XI

Glossopharyngeal: Taste post 2/3 tongue, swallow, salivation (parotid) carotid body, gag reflex

5

Innervation swallowing

CN IX, X

6

Innervation salivation

CN VII (submand, subling), XI (parotid)

7

Sensation: V, VII (taste ant 2/3), IX (taste post 1/3)
Movement: XII

8

Innervation carotid body, arch, sinus

CN IX: carotid body and sinus chemo and baro
CN X: cartoid arch chem and baro

9

Lateral corticospinal tract

Movement contralateral limbs

10

Dorsal column

Fine touch, vibration, conscious proprioception

11

Spinothalamic

Pain, temperature (crosses at level of spinal courd)

Biceps: C5, 6
Triceps: C7,8
Patella: L3,4
Achilles: S1,2
Babinski: UMN, normal first year

13

Presents with: Aphasia or neglect, contralateral paresis and sensory loss face and arm, gaze towards lesion, homonymous hemianopsia

MCA infarct

14

Presents with: Contralateral paresis and sensory loss in leg, cognitive or personality changes

ACA infarct

15

Presents with: Homonymous hemianopsia, memory deficit, dyslexia/alexia

PCA infarct

16

Presents with: Coma, "locked in" syndrome, CN palsies, apnea, crossed weakness and sensory loss of face/body

Basilar artery infarct

17

Presents with: Pure motor or sensory stroke, dysarthria-clumsy hand syndrome, ataxic hemiparesis

Basal ganglia lacunar infarct

18

Imaging for stroke

Emergent CT without contrast (rule out bleed)

19

Mnemonic: 4Ds of posterior circulation strokes

Diplopia
Dizziness
Dysphagia
Dysarthria

20

When can tPA and intraarterial thrombolysis be administered?

tPA: within 3 hrs
intraarterial thrombolysis: within 6 hrs

21

What can decr morbidity mortality within 48hrs of stroke

ASA

22

Treatment if incr ICP after stroke

Mannitol, hyperventilation

23

Target INR for AF and prosthetic valve

AF: INR 2-3
Prosthetic valve: INR 3-4

24

Drug for long term prevention after stroke

ASA, clopidogrel

25

Presents as: abrupt-onset, intensely painful thunderclap headache: dx, etiologies

SAH
Trauma, berry aneurysm, AVM

26

When is carotid endarterectomy indicated?

>60% in symptomatic
>70% in asymptomatic
contraindicated in 100% occlusion

27

What is associated with CNIII palsy with pupillary involvement

Berry aneurysm

28

What are first or second diagnostic procedures if SAH suspected?

1. CT without contrast
2. If neg, LP (Look for RBC, xantochromia)

29

Complications after SAH and prevention

Vasospasm: 5-7 days after, Ca channel blockers
Rebleeding: keep BP

30

Definitive treatment for cerebral aneurysm

Surgical clipping
