Primary headaches are headaches that are not due to tumors, we don’t know why we get them, and include
- migraine headaches
- tension headaches
- trigeminal autonomic cephalgias
- chronic daily headache

Important features in taking a history for headaches include:

- location
- laterality
- mode of onset
- duration
- nature: throbbing, aching, pressure, dull, sharp, thunderclap
Associated symptoms of headaches may include:
- visual aura
- photophobia
- phonophobia
- GI symptoms
- motor weakness
- sensory deficit
Secondary headache disorders include an ____ cause for the headache present
organic; tumor, aneurysm
The trigeminal nerve innervates:
- skin and blood vessels of scalp.
- dura
- venous sinuses
- cerebral arteries
- cervical and cranial muscles and blood vessels

distention
______% 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.
- vasoconstriction of cerebral vessels, which cuts off oxygen, and results in neurologic deficits.(visual aura’s on opposite side)
- vasodilation causes pain due to irritation of trigeminal nerve.
what are some migraine triggers?

- menstrual cycle
- insomnia
- hunger
- exercise
- scents
- weather
- 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

-photophobia/phonophobia
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:

-Speech or language disturbance.
C. At least TWO of the following are present:
