7

Besides SNOOP, what are the two headache danger signs mentioned in class?

"First or worst" headache*
Headaches not reponding to treatment

If a patient has a danger sign for a headache, imaging should be done, and typically an MRI is preferred over a CT (though CT is preferred in emergencies). Lumbar puncture should be performed if you are suspicious for either of what two conditions?

Meningitis or subarachnoid hemorrhage

9

Migraine headaches affect activities of daily living, are ___________ (unilateral/bilateral) and typically occur how many times per month?

Migraine with aura

13

The diagnostic criteria for a migraine without aura includes the headache lasting how long?

4 to 72 hours

14

The diagnostic criteria for a migraine without aura includes a headache with at least two of which four characteristics?

At least one aura symptoms spreading gradually over more than 5 minutes (and/or two or more symptoms occurring in succession)
Individual aura symptoms last 5 to 60 minutes
At least one aura symptom is unilateral
Aura accompanied by or followed within 60 minutes by a headache

16

The cortical spreading depression (CSD) theory of migraine pathophysiology states that aura are caused by a wave of excitation in parts of the brain. CSD is also said to activate the trigeminal system* and cause release of what neuropeptides?

Calcitonin gene-related peptide (CGRP)*
Substance P
Neurokinin A

17

The cortical spreading depression (CSD) theory of migraine pathophysiology states that aura are caused by a wave of excitation in parts of the brain. The permeability of the blood-brain-barrier is affected by what inflammatory markers?

COX-2, TNF-alpha, MMPs

18

True or false: the cortical spreading depression theory (CSD) states that nociceptor threshold is increased, and the magnitude of their response is increased as well.

False; the threshold is decreased (easier to feel pain), and the magnitude is increased

19

Migraines are associated with depletion of which endogenous substances? With excess of which substance?

Depletion of serotonin and estrogen; excess dopamine.
