Neurology random Flashcards
What get in GBS LP
ALbumin
4 As of GBS
Acute inflam demyel polyradi
Acute
A
First line management any MS patient with bladder dysfunction
US KUB - assess whether retention - depends what medication will use
Oxybutinin can worsen retnetion
Then -> methylpred if flare
Residual volume - self catheterisation
No residual volume - anticholinergics eg oxybutinin
CSF MS
Oligo clonal bands - not in serum
MRI contrast head in MS
Dawsons fingers
Periventricular white lesions
Lesions disseminated in space and time
Why is domperidone used in reducing nausea in parkinsons
Doesn’t cross BBB
SACD features
Loss of proprioception and vibration sensation
Muscle weakness
Hyperreflexia
SCD acronym features for SACD
Spinocerebellar tracts - sensory infromation - ataxia, +ve romberg
Corticospinal tracts motor tract
Dorsal columns - proprioception, vibration fine touch
Why replace B12 before folate
Because body uses up all og B12 with replaced folate until none left -> SACD
Pyramidal vs extrapyramidal
Pyramidal - vulantary
Extrapyramidal - epsies, eg movement disorders - tardive dyskinesia etc
Treatment for bells palsy
Bells palsy features
Unilateral facial weakness affecting forehead
Hyperacusis
30-40 women
Treat - predisolone + eye care
Bells palsy vs ramsay hunt
Ramsay hunt - auricular pain, vesicular rash, tinnitis
Bells - less ear features
Treatment for ramsay hunt
Prednisolone + aciclovir
Results ofSAH on LP
bilirubin +normal openeing pressure + xanthochromia
CT head SAH what see
sTAR SHAPE
sECONDARY PREVENTION for ischaemic strokes
2 weeks aspsirin = primary
Swap clopidogrel + atorvaastatin long term
When do mechanical clot retrieval in ischaemic stroke
After thrombolysis IF stroke occured in last 6 hours in proximal anterior circulation
Should happe within 6-24hours of last normal if potential to salvage brain tissue + limited infarct core volume
Where does a strke have to be for thrombectomy
Proximal anterior circulation with CTA or MRA
Features of idiopathic intracrania HPTN
headache
blurred vision
papilloedema (usually present)
enlarged blind spot
sixth nerve palsy may be present
Management of idiopathic IC HPTN
WEIGHT LOSS
Carbonic anhydrase inhibitors eg acetazolamide
Topiramate
Repeat LP short term
Surgery if optic nerve sheath compression and fenestration
What is acetazolamide
Carbonic anhydrase inhibitor used to treat idiopathic intracranial HPTN
Features of cerebellar tremor
Cerebellar tremor - coarse intention tremor increases with amplitude on reahc, can be unilaterl
