Neurology Flashcards
Bell’s palsy intermediate intervention and association
1mg/kg Prednisolone, associated with hyperacusis
Lateral medullary syndrome
One sided horner syndrome and nystagmus with opposite side sensory and motor deficit upper limbs
Anterior choroidal artery occlusion presentation
Contralateral weakness and sensory loss as well as as homonymous hemianopia
Superior cerebellar artery presentation
Unlike LMS, it present with vertigo rather than Horner syndrome
Somatisation vs conversion
Somatisation leads to mulitiple complaints across organ systems Conversion -> neurological complaints with loss of power or sensation
Proximal vs distal ant cerebral artery occlusion
Distal -> defects in aprietal lobe area Proximal -> unlikely much effect because of collateral blood supply
Niemann Pick disease MoA
Defect in lysosomes -> imapired lipid transport
What is Lhermitte’s sign?
Electric shock like pain in lower limbs following neck flexion -> indicates cervical myleopathy related to disc prolapse.
WHere does the facial nerve branch?
Just after stylomastoid foramen where it branches into chorda tympani supplying taste sensation to anterior two thirds of tongue and the other branch supplying muscles of face
Becker’s dystrophy underlying mechanism and presentation
Telomere shortening. Gradual worsening proximal muscle weakness, together with heart failure and rhythm abnormalities
Hydrocephalus in SAH presentation
Papilloedema and sixth nerve palsy on BG of stable neurological deficit
Difference conus medullaris vs cauda equina vs anterior spinal artery syndrome
Conus medullaris: lower limb weakness with increased tone and hyperreflexia + saddle anaesthesia Cauda equina: lower limb flaccid paralysis + saddle anaesthesia ASAS: like cauda equina but loss of pain and temperature sensation
How does amaurosis fugax present and site of lesion?
Transient occlusion of the opthalmic or retinal artery often due to embolism from atheroma from ipsilateral internal carotid artery External carotid artery does not supply retina
Functional areas of the brain
Functions of the different areas of the brain
Spinal Cord Lesions
NF type 1 vs type 2
Tuberous sclerosis
Autoimmune polyglandular syndrome type 1
Number of CAG repeats needed in Huntington’s
Difference syringobulbia and syringomyelia
what is meralgia paraesthetica?
What is mononeuritis multiplex
