Neuro Flashcards
Patient with progressive MS and spastic paresis along with a neurogenic bladder. Develops increasing difficulty with lower extremity weakness and gait impairment. What is the etiology?
UTI resulting in worsening of previously fixed deficit
Most likely brain met to hemorrhage
Renal cell carcinoma
Pt with new onset vertigo, dysarthria, horizontal nystagmus with right facial and left appendage numbness. Localize the lesion
Medulla
Infantile spasms, or west syndrome, is associated with what condition?
Tuberous sclerosis
Most appropriate test to order in suspected Guillian-barre
LP
Child who has worsening movement of appendages and recently recovered from strep. What test should you order to confirm the diagnosis?
Anti-DNase b
What medication manages excessive daytime sleepiness and cataplexy in a patient with narcolepsy?
Sodium oxybate
What feature of narcolepsy is considered specific and seldom ️Occurs outside?
Cataplexy
Most appropriate treatment of a patient in a myasthenic crisis
IVIG
What muscle is weak with prolonged entrapment of the median nerve at the level of the wrist?
Abductor pollicis brevis
Man with recurrent falls, changes in his speech, impaired vertical eye movement, bradykinesia, increased axial tone, dysarthria. What’s causing it?
Progressive supra nuclear palsy
-These patients tend to fall BACKWARDS
MRI shows hummingbird sign in sagittal plane and Mickey Mouse sign in coronal plane
Drugs use in both cluster and migraine headaches
Triptans
56 year old man with a fib who has abrupt left sided hemiparesis and left visual field cut. What is absolute CI to IV tPA use in stroke even under 3 hours?
Major surgery in the last 14 days, of which there would be difficult holding compression should the patient experience and ️Bleeding
Patient with increased sensitivity to sound in the left ear. MRI reveals posterior Fossa mass. What CN is damaged?
VII
Proper order for documenting the neurologic exam
Mental status
CNS
Strength
Sensation
Coordination
Reflexes
Gait
Paroxysmal hemicrania
Just like a cluster headache but only lasts for 2-30 mins
***COMPLETE response to indomethacin
SUNCT
Short unilateral neuralgiform headaches
Just like cluster headaches but last from 1 second-10 minutes
Tx: Lamotrigine
Prophylactic treatment for tension headache
TCAs
Intracranial pressure in IIH
> 250 mmHg
Alternative causes of a picture similar to IIH
Hypervitaminosis A
Tetracyclines
Dural venous thrombosis (if signs of visual changes, make sure to get an MRI to rule this out)
Huntington’s Disease Treatment
Tetrabenazine
- Profound dopamine depleting agent
- Also treat other sx. as expected because obv. this drug can lead to depression
Earliest deficit in Alzheimer’s disease
Physiologic lesion in the hippocampus
This area will also lose nicotinic receptors throughout the course of the disease
Neuroimaging in PSP
Degeneration of the midbrain and pons
Corticobasal Degeneration
Asymmetrical onset showing:
- Akinesis
- Apraxia
- Alien hand syndrome
- Pts. may have cortical involvement, increased DTRs, supranuclear gaze palsy
Neuroimaging shows contralateral loss of cortex
