DDx Flashcards
Etiology of an intracranial Aneurysm?
- ballooning/dilation of blood vessel wall
- traumatic or congenital rupture of the middle or anterior cerebral arteries or communicating branches of the circle of willis
SS of intracranial aneurysm?
- asym till rupture
- new or change in HA
- can compress other structures causing
+ ocular palsies
+ diplopia
+ squint
+ facial pain - bitemporal deficet indicate pressure on the optic chiasm
- homo hemiopia b/c pressure on optic chaiasm
- neuro deficits
- once intracranial pressure increases vommiting, dizziness and alterations in pulse and respiratory rates
- seizures
- kernigs sign
- B/L babinski
Tests for intracranial aneurysm?
- CT scan
Treatment for intracranial aneurysm?
- surgery
- lumbar puncture
Etiology of BPPB?
- b/c degen otoconia floating in the post semicircular canal
- debris gets stuck to the cupula making it heavier = cupulolithiasis
debris can float int he long arm of the canal as well causing inappropriate endolymph movement = canalolithiasis - most commong cause of vertigo
SS of BPPV?
- vertgio with certain head positions
- severe vertigo for seconds to mins
- horizontal nystagmus
- diminishes over month or 2
NO hearing loss
Tests for BPPV?
- Dix Hallpike maneuver
- take sitting patient w/ 45 deg head rotation into supine while maintian head turn
- once supint the vertigo and nystagmus will begin
Treatment for BPPV?
- Eply’s
- Semonts
- meds and surgery
Etiology for cervicogenic HA?
- referal from soft tissue
- trigeminalcervical nucleus allows referal of the pain from the neck to the head
SS of cervicogenic HA?`
- daily HA w/ neuro signs
- decreased ROM w/ pain
- restriction in the C spine especially occiput
- xray show arthrosis
Treatment of cervicogenic HA?
- SMT and soft tissue
Etiology of Classic Migraine (migraine w/ aura)?
- neurogenic, thought to be vascular
SS of classical migrane?
- female
- unilateral throbbing (pulsating) HA
- photophobia
- phonophobia
- prodrome: bild spot w/ lights, numbness, sensory loss, weakness
- nausea
- vommiting
Treatment of classic Migraine?
- SMT for chronic
- meds
Etiology of clsuter HA?
- unknown
SS of Cluster HA?
- middle aged male occurs over days or weeks and appear again weeks or months later - last 30 mins - triggered by alcohol or certain foods - Horner's syndrome \+ Pitosis \+ miosis \+ anhydrosis - severe - unilateral - periorbital - lacrimation stuff nose - facial swelling
Treatment of Cluster HA?
- meds
- chronic cluster low grade mob
- episodic cluster just exercise
Etiology of common migrane?
- neuro cause
- hypothetical causes
SS of common migraine?
- female
- unilateral
- pulsitile
- severe HA
- no neuro
- nausea and vomitting
Treatment of common Migraine?
- SMT
- meds
SS of concussion?
- post trauma
- loss of awareness or memory
- papilary sign and brainstem function intact
Treatment of concussion?
- ABC first aid and send to hospital
Eitology of Crainial nerve 1 (olfactory) lesion?
- ethmoid #
SS of CN 1 lesion?
- ansomia
