2 Headache, pt 1 Flashcards
First step in the management of headaches
Identifying those at high risk for a secondary headache
Features associated with high-risk headaches
Age >50y
*Thunderclap headache
Onset on exertion
Fever
Immunocompromised state
**defined as pain that reaches 7 out of 10 in less than 1 minute*
Medication overuse is defined as
Use of >10 times a month
Features suggestive of migraine
Photophobia/phonophoboia, Pulsatile/throbbing
lasts hOurs (4-72 hours)
Unilateral
Nausea/vomiting
Debilitating, moderate/severe intensity
Feautures suggestive of Cluster Headache
At least 5 attacks that meet the following:
- Severe
- Unilateral
- Lasts 15-180 mins (untreated)
- circadian/circannual pattern
associated with *ipsilateral symptoms (at least 1)
- lacrimation
- conjunctival injection
- nasal congestion/rhinorrhea
- ptosis and/or miosis
- edema of the eyelid and/or face
- sweaeting of the forehead and/or face
Classic triad of meningitis
Fever
Neck stiffness
Altered mental status
Headache makes this a tetrad
~95% of patients with bacterial meningitis present with at least 2 of these 4 findings
can be used to assess for papilledema
optic nerve sheath
normal is <5 mm
>6 mm is abnormal
5-6 mm is controversial
Remarks on papilledema
The presence of papilledema requires CT imaging before lumbar puncture
Lumbar puncture (LP) can be a therapeutic tool in
idiopathic intracranial hypertension
Perform LP in what position?
lateral decubitus position
to allow for the accurate measurement of opening pressure
It is safe to proceed with LP without imaging prior in patients with
normal sensorium,
no focal neurologic deficit, and
without a history of immunosuppression
Imaging prior to LP is appropriate in patients with
Altered or deteriorating level of consciousness (particularly a GCS ≤11)
Brainstem signs (pupillary changes, posturing, irregular respirations)
Czure (recent seizure)
Deficit (Focal neurologic deficit)
*Emmunocompromised state
Freexisting neurologic disorder
but NEVER delay antibiotic administration while imaging is obtained
Remarks on subarachnoid hemorrhage (SAH)
10% to 14% of those complaining of the “worst headache of their life” have SAH.
Acute onset of a severe headache is SAH until proven otherwise.
prognosis of SAH
SAH resulting from rupture of an intracranial aneurysm carries only a 50% 30-day survival rate
remarks on antiplatelets and ICH
The antiplatelet agent clopidogrel increases risk of acute iCH immediately after trauma, so patients receeiving antiplatelet agents and anticoagulants should be screened using head CT, regardless of symptoms
