46
Q

The suggested outpatient approach for withdrawal of overuse medications other than barbiturates, Opioids, Or benzodiazepines is straightforward:

  4. revisit possible triggers (preventative medications will be discussed later)

*Withdrawl from barbiturates, opioids or benzodiazepines is more complicated and won’t be covered here. These medications are best avoided for treatment of HA for this exact reason.

47

Q

Migraine attacks typically unfold through a sequence of events that occur over several hours to days, and usually go through 4 phases:

A
  1. Prodrome
  2. Aura
  3. HA
  4. Postdrome
50
Q

Describe the Prodrome phase

A
  1. occurs in up to 60% of patients
  2. symptoms include euphoria, depression, irritability, food cravings, constipation, neck stiffness and increased yawning
  3. symptoms begin 1-2 days before aura and/or HA onset
51
Q

Describe the Aura phase

A
  1. occurs in ~25% of pts having migraines
  2. usually visual, but can be sensory, verbal or motor disturbance
  3. typically precedes the HA, but can occur during an attack; may last 15-30 min before HA onset
  4. can also include language problems or motor weakness in limbs or face.
52
Q

-visual aura classically begins as

A

a small area of visual loss that expands to form different shapes

53
Q

-sensory aura can follow visual aura and typically begins as

A

tingling in a limb or side of the face

54
Q

Describe the Postdrome phase

A
  1. as the throbbing headache resolves, patients typically feel drained or exhausted
  2. sudden head movement may cause transient pain
55
Q

Describe the HA phase of migraines

A
  1. associated with certain features such as Sensitivity to light, Sound, Or movement; Nausea and vomiting often accompanied a headache
  2. Migraine patients are particularly sensitive to environmental and sensory stimuli- This sensitivity is amplified in females during the menstrual cycle.
56
Q

Migraines were previously thought to be caused by ____ while the aura phase was caused by ___

A

dilation of cerebral blood vessels,

vasoconstriction.
* Vasodilation is now widely considered to be a secondary phenomenon, and is not the initial cause.

57
Q

Describe the neurovascular migraine hypothesis of migraines

A

Current consensus is that migraines are caused by a primary neuronal dysfunction that results in a sequence of changes that account for the different phases of headache. Cortical spreading depression is a central mechanism in the initiation of migraine. This is a self-propagating wave of neuronal and glial (astrocyte) depolarization that spreads across the cortex

58
Q

Cortical spreading depression is believed to:

A
  1. cause the migraine aura
  2. activate trigeminal nerve afferents, which cause inflammation of pain sensitive meninges and dilation of affected cranial blood vessels, which generates the headache
  3. alter blood/brain barrier permeability by activating and upregulating proteases
59
Q

Tx of acute migraine HA

A
  • depends on severity of attack
    1. Trial combination of acetaminophen, ASA, And caffeine is by the FDA for the treatment of mild-mod. migraine
    2. NSAIDs (best if taken early in attack ie. prodrome sx)
    3. Failed NSAIDs/analgesic: Ergotamines and Triptans
60
Q

What are the 3 major drug categories that are effective for migraines

A
  1. Anti-Inflammatory agents,
  2. 5–HT receptor agonists (Also called triptans or ergotamines), and
  3. Dopamine receptor antagonist’s.
61
Q

Stimulation of the __ can stop an acute migraine attack.

Examples of selective and nonselective agonists

A

5-HT receptors

  • nonselective receptor agonists- Ergotamine And dihydroergotamine
  • selective 5-HT-1 receptor agonists- triptans
62
Q

How do triptans work to stop migraines

A

5-HT-1 receptor types are found in meningeal arteries, the trigeminal nerve, and vascular smooth muscle.
-There is an increase in the rate of brain serotonin (5HT) synthesis during migraine attacks, and triptans exert a negative feedback action as well as having an effect on pain pathways.

63
Q

When are 5HT agonists CI

A
  1. CV hx
  2. Cerebrovascular dz hz
  3. Do not combine w/ SSRIs as this can lead to serotonin syndrome
64
Q

Who are good candidates for migraine prophylaxis?

A
  1. those w/ increasing frequency
  2. attacks that are unresponsive, poorly responsive, or CI to abortive tx
  3. 5 or more attacks per month
  4. occurring 2 days/weeks
  5. HA that severely limits quality of life despite abortive therapy.
  6. Presence of uncommon migraine conditions including hemiplegic or basilar migraine, or migraine with prolonged aura
65
Q

What meds are used for migraine prophylaxis

A

FDA approved:

  1. Propranolol/Timolol
  2. Valproate
  3. Topririmates (anticonvulsant)

Not FDA approved

  1. TCAD- Amitriptyline and Nortriptyline
  2. Gabapentin

*The probability of success with any one of the antimigraine drugs is 50 to 75%.

66
Q

Describe how migraine prophylaxis meds work

A
  1. take daily and start w/ LD and gradually increase
  2. period of 2-12 weeks before effect is seen
  3. Once effective stabilization is achieved the drug is continued for approximately 6 months
  4. then slowly tapered to assess the continued need.
