Neuro exam Flashcards
what dzs are associated with abrupt onset neurological sxs
cerebral hemorrhage
vascular dz
infection
head trauma
what dzs are associated with progressive neurological sxs
neoplasm
degenerative dz
what dzs are associated with intermittent neurological sxs
demyelinating dz
what must be eliminated before dementia can be dx
depression and delerium
what do you have to do before testing CN I
make sure nasal passages are clear
what is evaluated by the near response
- pupillary constriction
- medial rectus (convergence)
- ciliary m (lens accomodation)
what is presbyopia
farsightedness AKA impaired NEAR vision
what is the progression of CN III sxs from space occupying masses
first pupil dilation and fixation
THEN down and out position
what CN is responsible for inward rotation, downward and lateral movement
CN IV
what CN is responsible for only lateral movement
CN VI
what CN lesion is assoc w/ vertical diplopia and how might this present
CN VI, difficulty reading for walking down stairs
in CN IV which way does the head tilt
opposite to the lesion
what is the most common isolated nerve palsy
VI
what CN lesion is associated with convergent strabisus or esotropia
CN VI
what CN lesion is assoc w/ horizontal diplopia
CN VI
when is physiologic nystagmus seen? which direction is the beat?
seen in extreme deviation of gaze
eye beats in opposite direction of gaze
what CNs are evaluated by the corneal reflex
V and VII
which way does the jaw deviate in a trigeminal lesion
toward the weak side
what CN is responsible for saliva and tear secretion
VII
what CN lesion causes hyperacusis (inc sensitivity to sound)
VII
aberrant regeneration of what CN causes crying w/ chewing
VII
supranuclear or central facial palsy spares what part of the face
upper
what CN lesion is associated w/ disequilibrium and nystagmus
vestibular division of CN VIII
what CN lesion is assoc with sensorineural hearing loss and tinnitus
cochlear div of CN VIII
