Primary headaches are headaches that are not due to tumors, we don't know why we get them, and include

1. migraine headaches
2. tension headaches
3. trigeminal autonomic cephalgias
4. chronic daily headache


Because the eye receives a rich innervation from CN ____, many headache syndromes are associated with pain concentrated around the eye



Important features in taking a history for headaches include:

1. frequency
2. location
3. laterality
4. mode of onset
5. duration
6. nature: throbbing, aching, pressure, dull, sharp, thunderclap


Associated symptoms of headaches may include:

1. visual aura
2. photophobia
3. phonophobia
4. GI symptoms
5. motor weakness
6. sensory deficit


Secondary headache disorders include an ____ cause for the headache present

The trigeminal nerve innervates:

3. venous sinuses
4. cerebral arteries
5. cervical and cranial muscles and blood vessels
6. CN II and III


Headache pain may result from tension, _____, dilation, inflammation ,and/or pressure applied to any one of the pain sensitive structures



______% of women exp migraine headaches, and the highest prevalence is in 30-50 year olds. 90% have disability of some sort and many patients self treat with OTC analgesics.



explain the mechanism of a migraine.

1. vasoconstriction of cerebral vessels, which cuts off oxygen, and results in neurologic deficits.(visual aura's on opposite side)
2. vasodilation causes pain due to irritation of trigeminal nerve.


what are some migraine triggers?

1. stress
2. menstrual cycle
3. insomnia
4. hunger
5. exercise
6. scents
7. weather
8. foods: nitrate in preserved meats, chocolates, caffeine, cheese


Two major types of migraines are with aura and without aura. With aura is a _____type of migraine. It includes transient focal neurological symptoms that precede/sometimes accompany the headache. Without aura is a recurrent headache disorder without preceding neurologic symptoms



Migraine without aura often has a ______relationship. It includes a positive family history, and peak onset is in 2nd-3rd decade.



What is the IHS diagnostic criteria for migraine without aura

A. 5 attacks fulfilling criteria B-D.
B. Headache lasting 4-72 hours (with/without treatment)
C. Headache has atleast 2 of the following characteristics:
-unilateral location
-pulsating quality
-moderate to severe intensity
-aggravated by routine physical activity
D. During headache, at least one of the following occurs:
E. not attributed to another disorder.


Migraine with aura happens because of _______phase happening first. You get a scintillating scotoma (zig zag flashing light), parastheisias in parietal lobe (opposite side), aphasias (temporal lobe -cant verbalize), and ______which affects your motor pathways. Headache comes after or occurs in tandem with aura, and is always confined to one hemisphere. (opposite of where their visual aura has been.)

vasoconstrictive; hemiparesis


What is the diagnostic criteria of migraine with aura.

A. At least two attacks fulfilling criteria B-D.
B. Fully reversible aura consisting of at least ONE of the following, but NO motor weakness:
-visual symptoms include positive features: flickering lights or spots or negative features (vision loss)
-sensory symptoms including positive features (pins and needles) and/or negative features (numbness).
-Speech or language disturbance.
C. At least TWO of the following are present:
-Homonymous visual symptoms/unilateral sensory symptoms.
-At least ONE aura dev's gradually over > 5 mins and or diff aura symptoms occur in succession over > 5 mins.
-Each symptom lasts > 5 mins and


The difference bet migraine and TIA is that migraine contains _____visual symptoms, gradual onset/evolution, repetitive attacks of identical nature, flurry of attacks in midlife, lasts



Basilar artery migraine is a subtype of migraines and is very rare. It involves the distribution of basilar artery which supplies the ______. Symptoms include diplopia (brainstem nuclei), ataxia and poor coordination (cerebellum), and speech problems.



Complicated migraine is a permanent neurologic deficit, visual, motor, or sensory. Usually located in _____-parietal regions. there is no effective therapy for evolving complicated migraine. Sublingual calcium channel blockers may help reduce vasospasm.



Retinal migraine is another migraine subtype. It is usually ______, with negative visual phenomena (graying or blacking out of vision). It is a diagnosis of exclusion. May see constriction of retinal arterioles and venues during _____episodes but rarely leaves permanent deficits. Must evaluate carotid doppler and possible blood workup: hyper coagulate state in a young ind, or antiphospholipid antibodies.

unilateral; active


Acephalgic migraine, includes transient neuroligic events WITHOUT headache. If present in patients > 40 years, you have an inc. risk for TIA. You need to do an MRI to rule out structural lesions. Consider ______in any age group. Distinct features include buildup of ______, episodes last longer than TIA, and usually a remote history of migraine headaches. Treatment includes aspirin or _____ channel blockers

seizures; scintillations; calcium


migraine diagnostic testing includes:

1. threshold visual fields: exclude permanent deficits
2. ESR: elderly patients (65+)
3. MRI: only if red flags are present
4. LP: if arachnoid hemorrhage, meningitis, or IIH suspected.


what does treatment for migraines include

1. abortive therapy: for pain, no treatment for visual aura
-OTC: acetominophen and NSAIDs
-Triptan: migraine specific
2. preventive therapy:
-beta blockers
-ca channel blockers
-anticonvulsants: topiramate, gabapentin, valproic acid


Tension headaches are ____and episodic. Described as "tightness," usually in a band like distribution. Triggers contraction of the _____ muscle and cervical musculature in the neck, so headache is due to muscle spasm or stiffness. There is no photophobia, photophobia, or disruption in activity. May occur in tandem with migraine.



Common locations of headache are:

1. over the eyes
2. top of the head
3. over the temples
3. over the occipital region.
-most are episodic with pain free intervals
-usually relieved by OTC pain meds


chronic daily headache occur ____days per month, and rep evolution from migraine or tension headache. It may be due to ____ rebound. Associated with narcotic use _____ days per month or OTS analgesic use _____ times per month. Treatment is to taper the overused meds and may require hospitalization for IV therapy depending on severity and duration of overuse.

15+; analgesic; 10+; 15+

Chronic: occurs over one year without remission period, or remission periods lasting less than one month.


Onset of cluster headaches are usually ____to 30 years of age. MEN have it more. Pain is localized to the eye, temple, forehead, or cheek region. Associated with ipsilateral autonomic symptoms. ____is a common trigger. Treatment includes oxygen or _____
