1

What is the Rx for ADHD?

Methylphenidate

2

What is the MOA of Methylphenidate?

Amphetamine--indirect sympathomimetic
Increases release of DA, NE

3

Name 2 S-100+ tumors.

Schwannoma
Skin, melanoma

4

What is the Rx for Restless Leg Syndrome?

Levodopa

5

What kind of stroke affects the (contralateral) upper extremity more than the lower extremity and 2/3 of the face?

MCA stroke

6

What are the findings of an MCA stroke?

Affects contralateral uppers > lowers
+ 2/3 face

7

What infarct syndrome affects ipsilateral CN III + contralateral body?

Weber's Syndrome
- Basilar or PCA

8

What are the sequelae of a stroke to the Basilar Artery or the PCA?

Weber's Syndrome:
- Ipsilateral CN III
- Contralateral body

9

What kind of brain bleed can present with symptoms minutes or months after trauma (fall) occurred?

Subdural hematoma

10

What vessels are ruptured in a subdural hematoma?

Bridging cortical veins

11

What does a subdural hematoma look like on CT?

Moon-like sliver against the skull

12

What vessels are ruptured in an epidural hematoma?

Middle Meningeal

(bleed bends towards the MIDDLE of the brain)

13

What does an epidural hematoma look like on CT?

Bleed is convex and bends towards the middle of the brain, like a lower case 'e' abutting the skull

14

What vessels are ruptured in a SAH?

Usually Berry aneurysm

15

What does a SAH look like on CT?

Spotty bleeding in anterior brain

16

What vessels are ruptured in an intracerebral (intraparenchymal) hemorrhage?

Lenticulostriate arteries of the internal capsule

(internal capsule bleeds STRAIGHT (striate) into the brain)

17

What does an intracerebral (intraparenchymal) hemorrhage look like on CT?

Big burgeoning bleed in the middle of the brain

18

What kind of bleed is caused by a Charcot Bouchard aneurysm?

Intracerebral (intraparenchymal) hemorrhage

19

What is a complication that occurs 4-12 days after SAH?

Vasospasm, causing ischemia and new deficits

20

What med can prevent vasospasm post SAH?

Nimodipine

21

What is the path of the Glossopharyngeal nerve (IX) within the brain (origin and exit)?

Medulla to Jugular Foramen

22

What muscle does the Glossopharyngeal nerve (IX) innervate?

Stylopharyngeus

23

To what gland does the Glossopharyngeal nerve (IX) carry PS fibers?

Parotid

24

What nerve provides sensory information from the inner surface of the tympanic membrane, Eustachian tube of the ear, posterior 1/3 tongue, tonsilar region, upper pharynx, and carotid body sinus?

Glossopharyngeal nerve (IX)

25

What nerve is responsible for the afferent gag reflex?

Glossopharyngeal nerve (IX)

26

What nerve is responsible for the efferent gag reflex?

Vagus nerve (X)

27

What is the MOA of phenytoin?

Inhibits neuronal high frequency firing by reducing the ability of Na+ channels to recover

Less Na+ current = less seizure

28

What is the first line Rx for status epilepticus?

Benzos

29

What Rx is used to prevent recurrence post status epilepticus?

Phenytoin

30

Keeping Schizo- Straight:

Distant

Schizoid
