Q

what is strong correlated with deceased cognition

A

lacunar stroke

24
Q

Embolic

A

20-30% air or water

rapidly without warning

25
hemorrahagic
hypertension, aneurysm and arteriole venous malformation | younger ppl
26
hypertensive hemorrhage
increase SP/DP blood mass created compresses brain tissue massive or small
27
types of hypertensive hemorrhages
massive, small and slit (lies in subcortical area)
28
Stroke treatment
TPA
29
Progression and Risk of stroke
Age (1 - 60+) BP (1 >140 or /90) Clinical features (2 hemisphere weakness, 1 speech) Duraction (2 >60, 1 less )
30
ABCD
predict progression of stroke / recurrent stroke
31
arterial factors that contribute to stroke
vessel walls | damaged vessels
32
vessel walls contribute to stroke how
plaque dissecting walls pressure or damage to walls
33
venous factors that contribute to stroke
blood clots quick for them infection / trauma to inner vein lining sluggish flow of blood deep vein thrombosis
34
deep vein thrombosis
inactivity (planes) surgery can cause stroke, heart attack or pulmonary embolism
35
what preserve leg motor and sensory function after stroke
ACA and MCA anastomoses
36
arterial risk at the neck
vertebral arteries | internal carotid
37
ischemic stoke responses
neuronal
38
neuronal responses
death penumbra cell death in cerebellum/hippocampus degeneration
39
ischemic penumbra
area of marginal perfusion
40
when is too early to intervene
never
41
acute treatment stroke
``` thrombolytic agents (TPA) Mechanical embolus clot removal ```
42
TPA does what
dissolves clots salvage pneunbral tissues (if within 3 hrs) won't be hemorrhagic
43
mechanical embolus clot removal
screwed into clot | 8 hours post onset
44
prevention of recurrent stroke
aspirin lifestyle exercise lipid lowering agent
45
ischemic vs hemmorrhagic stroke
h: better long term prognosis
46
factors influencing upper limb motor recovery
integrity of pyramidal motor ouput | esp for fingers
47
T/f small injury to corona radiate not important
false - its significant
48
what predict change associate with motor learning
white matter
49
Apahsia
lesion to broca (expression) | lesion to wernike (receptive)
50
Apraxia
motor disorder from lesion to posterior parietal lobe ideomotor constructional ideational
51
ideomotor
can explain perform voluntarily but not complete movements on command
52
constructional
can't draw shapes
53
ideational
can't create motor plan | can't relate object to use
54
neuroplasticity after stroke
depends on dose of skilled movement
55
dosage for problems in stroke
LOTS
