stroke==>what type of body posture
|
I. typical stroke is in CEREBRUM d/t carotid artery occlusion (ABOVE red nucleus in midbrain)
==>decorticate posturing (deCORTicate b/c closer to CORTex) *wrists and elbows flexed *ankles and knees extended II. if stroke is in midbrain (BELOW red nucleus of midbrain) ==>dEcErEbrate posturing *"E"xtension of "E"xtensors (elbows and wrist) |

Argyll Robertson pupil
|
"Prostitute's pupil" b/c:
1. d/t tertiary syphilis 2. "accomodatexs but does not react" (accomodates [near vision] but does not react to light) |

INO
-what causes it -desc |
INO=InterNuclear Opthalmoplegia
-AKA MLF syndrome (MLF=Medial Longitudinal Fasciculus) =bilateral lesion of MLK -d/t MS -neither eye can look medially when say "look left: and "look right" -but eyes can converge (go medially at same time) b/c convergence is mediated by another system, not the MLF |

calorics
-tests what -desc |
-calorics tests brainstem function
"COWS" indicates NORMAL response (intact brain stem): "COWS"= Cold Opposite, Warm Same -direction refers to direction of FAST phase of nystagmus: -Put COLD water in ear==> NORMAL response is: 1. Slow nystagmus toward water 2. Fast nystagmus AWAY water ABNL response=no mvmt at all (i.e. pt in coma==>depressed brain stem==>no mvmt) |

Doll's eye phenomenon
-tests what -desc |
-tets brain stem function
"INTACT Doll's Eye" is the NORMAL response (intact brain stem): -when tilt head back, eyes move down (like a doll) "ABSENT Doll's eye"=ABNL response: -when tilt head down, eyes do not move |
