males

10

  • may have aura
11
Q

Migraine mnemonic

A

POUND

Pulsatile, One-day duration, Unilateral, Nausea, Disabling

12
Q

migraine is due to

A

irritation of: 1. CN V 2. Meninges 3. Blood vessels

13
Q

migraine due to blood vessel irritation - mechanism

A

release of substance P, calcitonin gene-related peptide, vasoactive peptide

14
Q

cluster headache - treatment

A

acute: 1. 100% 02 2. sumatriptan
prophylaxis: verapamil

15

tension headache - treatment

A
  1. Analgesics
  2. NSAID
  3. acetaminophen
  4. Amitryptyline for chronic pain
16
Q

Migraine - treatment

A

Acute: triptans, NSAIN, dihydroergotamine
ProphylaxiS: lifestyle changes (sleep, exercisem diet eg,) propranolol, topiramate, Ca2+ channel blockers, amitriptyline, valproate

17
Q

trigeminal neuralgia headache - duration / type of pain

A

typically less than 1 minute

repetitive shooting pain in distribution of CN V

18
Q

Vertigo - definition

A

sensation of spinning while actually stationary. (subtype of dizziness but distinct from lightheadedness

19
Q

types of vertigo (MC?)

A
  1. peripheral vertigo (MC)

2. central vertigo

20
Q

peripheral vertigo - etiology

A

inner ear etiology

  1. semicircular canal debris (benign position vertigo)
  2. vestibular nerve infection
  3. Meniere disease
  4. ototoxic drugs
  5. Ramsay Hunt syndrome
21
Q

peripheral vertigo - diagnosis

A

positional testing –> delayed horizontal nystagmus

22
Q

causes of central vertigo

A

Brain stem or cerebellar lesion

eg. stroke affecting vestibular nuclei or posterior fossa tumor

23
Q

central vertigo findings

A
  1. directional change of nistagmus
  2. skew deviation
  3. diplopia (eyes)
  4. dysmetria
  5. focal neurological findings
24
Q

dysmetria

A

lack of coordination of movement typified by the undershoot or overshoot of intended position with the hand, arm, leg, or eye. It is a type of ataxia.

25
Q

central vertigo diagnosis

A
  1. positional testing –> immediate nystagmus in andy direction, may change direction
