1

Criteria of migraine w/o aura

*5+ attacks with the following:
- headache for 4-72h
- headache as at least 2 of these things: u/l, pulsating, moderate-severe intensity, aggravated by physical activity
- N/V, photophobia, phonophobia (1)
- H&P or tests do not show another etiology

2

criteria of migraine w/ aura

*2+ attacks that have at least 3 of the following:
- 1 or more reversible aura
- 1+ aura symptoms develops over 4 minutes or 2+ symptoms in succession
- no aura lasting more than 1h
- headache follows aura
- H&P and test show no pathology

3

types/examples of auras

- aura = warning sign for a migraine
- lasts 15-30minutes and happens before, during or after head pain begins
1. visual - scintillating scotoma, fortication spectra
2. paresthesias - numbness in face/hands
3. weakness - hemiplegia on one side
4. aphasia
5. vertigo
- migraine equivalent: 1 of these happens by themselves w/o the headache

4

prodrome and symptoms

- premonitory phenomena preceding headache by hours to days
- symptoms include: mental and mood changes, stiff neck, chilled feeling, increased urination, anorexia, bowel changes, food cravings, fluid retention
*not the same as auras

5

migraine: pathophysiology

- aura phase associated w/ reduction in cerebral blood flow
- spreading of oligemia at 2-3mm/min
- oligemia progression doesn't respect vascular territories
- oligemia seen in migraines w/ and w/o aura
- phenomenon = "spreading depression"
- pain generated by sterile neurogenic inflammation
- CGRP gene release via trigeminovascular system that is activated as protective mechanism in response to oligemia

6

criteria for tension headache

- at least 2 of the following: pressure/tightening quality, mild-moderate intensity, b/l location, not aggravated by exertion
- no N/V, photophobia, phonophobia
- No H&P or tests find other etiology

7

episodic tension headache: frequency/duration

- at least 10 previous headache episodes:
<15d/month
- headaches last 30 minutes to 7d

8

chronic tension headache frequency

- average headache frequency = >15d/month for longer than 6 months
- psychosocial/psychiatric issues are more common in these pts

9

factors confounding dx of tension headaches

- stress triggers
- b/l or non-pulsating head pain
- presence of neck pain
*in pts w/ these symptoms you need to consider dx of migraines; find a way to r/o one or the other

10

cluster headache criteria

*5+ attacks fulfilling:
1. severe u/l orbital, supraorbital, and/or temporal pain lasting 15-180m untreated
2. Has 1 of the following symptoms on same side as pain: conjunctival injection, lacrimation, nasal congestion, rhinorrhea, forehead/facial sweating, miosis, ptosis, eyelid edema
3. frequency = 1 every other day to 8 per day
- No H&P or test suggest other dx

11

cluster headache characteristics

- onset younger than 19yo
- male predominance
- usually occurs at night, often at same time each day
- paces or pounds fist or head w/ attack
- may commit suicide

12

criteria for sinus headache

- considered secondary dx from acute sinusitis
- requires presence of purulent nasal discharge and pathologic sinus findings in tests including xray, CT or MRI
- chronic sinusitis is not validated as a cause of headache or facial pain unless relapsing into an acute stage
