Q

It is nearly impossible to differentiate a first time MS attack from ADEM. When would MS be the more likely diagnosis when comparing to ADEM?

41
Q

Wilsons disease is a disorder of __ metabolism that produces __ dysfunction

Tremor

Levodopa

49

Location of Lewy bodies: __

When dementia occurs: ___

Resting tremor? ___

Autonomic dysfunction? ___

Hallucinations with/without anti-PD drugs? ___

A

PD=MIDBRAIN lewy bodies; Lewy body disease=Cortical lewy bodies

PD=Executive dementia sometimes late in illness; Lewy body disease=Cortical dementia always occurs early in illnesss

PD=Resting tremor usually present; Lewy body disease=Resting tremor usually absent

PD=Autonomic dysfunction sometimes seen; Diffuse lewy body disease=autonomic dysfunction prominent

PD=Hallucination only in response to anti-PD drugs; Lewy body disease=Hallucinations common in absence of anti-PD drugs

52
Q

Normal pressure hydrocephalus is potentially reversible with __

Ventriculoperitoneal shunting (gait disturbance is the most likely to be reversed with shunting)

53
Q

___ has a typical age of onset of 40-50 yrs of age, is a hereditary stroke disorder with a defect in NOTCH3 on Chr 19 causing progressive degeneration of smooth muscle cells in blood vessels. It commonly manifests as migraines and TIAs or strokes. Eventually progresses to Subcortical Dementia. No specific tx exists but antiplatelet agents and minimizing risk for vascular disease can be helpful

A

CADASIL

54
Q

___ has an unknown cause, characterized by amnesia only for a few hours (3-4), no other focal neurologic signs, all tests are normal, self-resolving, and almost never recurs

A

Transient global amnesia

55
Q

What are some Worrisome signs AKA signs which may indicate HA of pathologic origin (Secondary HA)?

A
  • Worst HA ever (berry aneurysm) –> CN III palsy with PCoA rupture
  • Onset of HA after age 50
  • Atypical HA for pt
  • HA w/ fever
  • Abrupt onset (seconds to minutes)
