Notes by triplehelix.
I did MKSAP 1 4 qu estions and made notes based on the key points,
and I plan to rev iew th is note before m y test. I thought to share th is
notes with y ou gu y s.
MKSAP 14 neur ology notes:
1 . A spinal cord disorder should be considered in an y patient w ith
bilateral motor and sensory dy sfunct ion in the extrem it ies in th e
absence of signs or sy mptoms of brain or brainstem dy sfun ction.
2. Spinal cord compression due to epidur al m etastasis is a neur ologic
emerg ency for wh ich u rg ent MRI of the entir e spine is appropriate.
3. Vertebral ar tery dissection ty pically presents with neck or h ead
pain, Horner's syndrome, dysarthria, dysphagia, decreased pain andtemperatu re sensation, dy smetria, ataxia, and v ertigo.
4. Magnetic r esonan ce ang iogr aphy is a sensitiv e diagn ostic test for
v ertebr al artery dissection as a ca use of str oke.
5. Ju v enile my oclonic epilepsy is a primar y , genetic, generalized
epilepsy that ty pically m anifests with m y oclonic jerks followed by a
generalized tonic–clonic seizure
6. Guillain–Barr é sy ndrome is char acterized by proxima l an d distal
weakn ess, autonomic sy mptoms, cr ania l nerv e inv olv em ent, and
respiratory failur e.
7 . Treatm ent of Guillain–Barré sy ndrom e with either intrav enous
imm unoglobulin or plasmapheresis is indicated in patients wh o
cannot walk independently or who have impaired respiratory
function or ra pidly progr essiv e weakn ess.
8. Sma ll, stable, asy mptomatic m eningiomas can be followed with
serial neur oima ging.

9. In larg e, sy m ptom atic, or progressiv e m eningioma s, surg ical
resection offers an 80% ch ance of cur e.
1 0. Personality chan ge, lost initiativ e, and slowing of though t, w ith
relat iv e preserv ation of recent m emory , suggest frontotemporal
dementia.
1 1 . Frontotempora l dementia is usua lly associated with
disproportionate atrophy of the anterior frontal and temporal lobes,a finding that is usually clearly demonstra ted on MRI.
1 2. Elevation of the cerebrospinal fluid 1 4-3-3 protein in a patient
with rapidly progr essiv e dem entia and norm al str uctural im aging
suggests Cr eutzfeldt–Jakob disease.
1 3 . Treat ment w ith in terferon-beta decreases the incidence of
additional a tta cks in patients with m onosy mptomatic

18. High-dose intravenous corticosteroids are indicated for initial
treatm ent of acute transv erse my elitis.
19. Secondary prevention of cardioembolic stroke consists of
warfarin with a target INR of 2.0 to 3.0.
20. Hepar in has no established role in th e acut e treatment of stroke.
21 . Th e m anifestat ions of partia l seizur es depend on their
neur oana tomic location.
22 . Fronta l seizur es ar e brief and are usually not associated with
aura or postictal confusion.
23. Hereditary sensorimotor neuropathy is an autosomal dominant
disorder that usually presents with clumsiness or difficulty running
in t he first decade of life.

considered for im m un omodulatory therapy with either a form of
interferon-beta or glatiramer acetate.
30. Adult-onset idiopathic dy stonia is usually focal or segm ental a nd
does not genera lize to other par ts of the body .
31. Botulinum toxin injections can correct the abnormal posture

34 . Cerv ical spondy losis is a ch ronic disorder of degenerativ e and
hypertrophic changes of the vertebrae, ligaments, and disks that
ma y nar row th e spinal cana l and cause cerv ical spinal cordcompression.
35. In patients with stroke not eligible for th romboly tic therapy ,
aspirin m odestly reduces both the short-term risk of recur rent stroke
and the long-term risk of stroke-related death and disability .
36 . In patients with acute stroke, thromboly tic therapy mu st be
star ted within 3 hours of the onset of sy m ptom s or of the time the
patient w as last known to be well.
37 . Elderly patients may be particular ly sensitiv e to the cognitiv e,
motor, and coordination side effects of phenytoin, even if the serum
pheny toin lev el is in the therapeutic ra nge.
38. Gabapentin, lam otrigine, an d carbam azepine are equally
effectiv e at controlling par tial onset seizur es in th e elderly , but
gabapentin and lam otr igine are better tolerat ed.
39 . Peripheral nerv ous sy stem v asculitis usually presents with
