Approach to Neuro Cases Flashcards
what are the three types of headaches?
tension, migraine, cluster
what is the duration of a tension ha?
minutes-days
what is the duration of a migraine ha?
4-72 hrs
what is the duration of a cluster ha?
15 minutes-3 hrs
what is the characteristic of a cluster ha?
quick onset “ice pick headache”
where is the location of a tension headache?
bilateral starts posteriorly and radiates anteriorly
where is the location of a migraine headache?
unilaterally- temporal/ frontal region
where is the location of a cluster headache?
unilateral- eye/temple region
what do the SNOOP signs possibly represent?
a space-occupying mass, vascular lesion, infection (red flags)
what does the s in snoop stand for?
systemic symptoms (fever weight loss)
what does the n in snoop stand for?
neuro symptoms
what does the first o in snoop stand for?
older onset (over the age of 50)
what does the second o stand for?
onset sudden-thunderclap headache
what does the P in snoop stand for?
papilledema or progression or change in HA history
if a patient has episodic dizziness/vertigo that is triggered what might they have if the dix-hallpike maneuver is positive?
BPPV
what is spontaneous vertigo that is associated with hearing loss?
meniere disease
what is meniere’s disease caused by?
increased endolymphatic pressure in the inner ear
what three aspects make up “titrate the evaluation of Dizziness”?
timing of the symptom, triggers, targeted examination
what are the three clinical scenarios of vertigo?
episodic triggered, spontaneous episodic, continuous
how can you diagnose BPPV?
using the dix-hallpike maneuver
what is orthostatic hypotension?
positional changes that result in acute drop in blood pressure
what medication can exacerbate orthostatic hypotension?
beta-blockers
what are two examples of neuro mediated (reflex) syncope?
carotid sinus syndrome and vasovagal
what is carotid sinus syndrome?
head rotation along with pressure applied to the carotid artery resulting in stimulation of carotid sinus –> possible syncope
what is vasovagal?
it occurs as an over correction to stimulus of sympathetic nervous system (panic, pain, sight of blood), resulting in rebound over stimulation of PNS resulting in bradycardia and vasodilation
