false, also mental
does stroke only affect old people
no , young too but more rate
What do you think is your role as a KCEP in the rehab process of your client? (of strokeO
incraase functional and fitness levels through exercise training
stroke is a type of injury to what organ
brain
what is a stroke
An abrupt incident of vascular insufficiency or of bleeding into or immediately adjacent to the brain
a blockage stroke is called
ischemic
stroke is the BLANK leading cause of death behind heart diseases and cancer
3rd leading cause
how many stroke cases are there in canada per year
60k-70k
740 000 canadian adults
what percentage of stroke attacks are first attacks
80%
what percentage of strokes are reoccruent attacks
20%e
what is the average age of onset of stroke
72
since the average age of onset is 72, strokes only happen to older populations
false, they can only occur in children and young adults as well
what percentage of stroke causes are under the age of 65
1/4
is the incidence of stroke equal in men and woman
yes
which gender is more likely to survi ve a stroke
women
what percentage of strokes result in death
29%
is the percentage if strokes that result in death lower or higher for younger people
lower
ischemic strokes account for what percentage
80%
what are the 2 causes of ischemic stroke
cerebral thrombosis
cerebral embolism
what is cerebral thrombosis
Development of a blood clot in a cerebral vessel (occlusion at atherosclerotic plaque)
what is cerebral embolism
Displaced clot of bacterial mass that occludes downstream artery
=blood clots can break free from an thrombosis and lead to an occlusion
when does ischemic strokes usually happen
periods of decreased acitiy (sleep)
is conciousness preserved during ischemic strokr
ues
inntracerebral hemorage acounts for what percent of total strokes
20%
what stroke is bleeding into the brain
intracerbral hemograge
what is the main cause of intracebreal hemorage
arterial rupture
what are the 2 principle causes of stroke i
ischemic and intercerbral hemorage
what percentage of strokes are intracerbral hemmorage
20%
whatt is arterior reupture associated with
Associated with aneurysms and arteriovenous malformations:
when do intracebral hemmorages occur
during periods of acvtiyty
what is the LOC for itracebral hemmorage
stupor or coma
what are the 5 signs and symptoms of stroke
weakness trouble speaking vision problems headache dizziness
explain weakness as a sign
Sudden loss of strength or sudden numbness in the face, arm or leg, even temporary
explain trouble speaking as a sign and is it assocaited with stroke i nthe left or right hemistpeherw
Sudden difficulty speaking or understanding or sudden confusion, even temporary (aphasia)
left
why do people have trouble speaking during a stroke
due to a stroke located in the left hemi
explain vision problems as a sign
Sudden trouble with vision, even temporary
wexplain headache as a sign
sudden sever and unusual headache
explain dizness as a sign
Sudden loss of balance, especially with any of the above signs (why?)
why is dizziness not a good sign alone
because you can be dizzy to many factors
fast is an aconym for
face, arms, speech and time
why does the fast test do
allows people to trecognize the signs of sroke
what is the fast test
ask person to smile
ask person to speak a simple snetence
ask person to raise both arms
=if they cannot do any of the 3 things get them to a hospital
Following a stroke, sensory and motor impairments are located on which body side?
opposite side as brain lesion
what is the most dominant risk factor for stroke
age!!
why is the incidence of stroke inreasing as time icnreases
because average populationn age is increasing
What is the median age (divides population into 2 groups of equal size) of the Canadian population?
40
what are the 3 risk factors we cannot control
age
sex
family hisotry
increases age is the dominant risk factor for strokr?
true
what is the relationsjip between heart disease and age
all major forms of heart disease increase with advancing age
as the canaidan population increased, what is expected in terms of stroke
number of individauls with heart disease and stroke will increase
true or false, the incidience for women and men are the same for strokr
true
what is another important risk factor besides age for strokr
family hisoty of early coronary disease
what is an independant risk factor for stroke
family histry
facots that contribute to the assocationn of fam hisotry and CAD may include what
familial dyslipedimia, lifestule and molecular defects in vascular physiology which render the vessel walls more susceptible to atheroscelorsis
what are 2 examples of modifable risk factors for strokep
physicial inactivtiy
high BP
which age groups were very phydscually inactive
5-11
12-17
60-79
WHAT CAN REGULAR PA redcude
Regular physical activity (PA) can reduce body weight, improve serum lipids and cholesterol, blood pressure and diabetes, and thereby overall stroke risk
national guidelines recomend what in terms of PA
recommend 150 min of moderate- to vigorous- intensity aerobic PA per week
High BP is a major risk factor for what
both coronary artery disaese and stroke peripheral vascular disease and congestive heart faility
High BP incrased overall cardiovascular risk by what
by 2 to 3 fold
which individuals are more liekly to develop high BP
indivudals who have excess weight , are physically inactive, use alcohol heavily, excesive salt intake
what type is the best exercuse program for stroke prevention
aerobic training
what are the 2 modes of training that are beneficials
aerobic training and fucntional training
aerobic rtaining decraes risk of 1st or 2nd stroke
2nd
what are the beneficial effects of aerobic rtaining
Reduced hypertension
Reduced body fat
Increased ratio HDL/LDL
what dies functinal trainingn icnrase
increase ADLS and QoL
what are the beneficial effects of functional trianing
Improve muscular strength and endurance
Improve motor functions (walking, balance, coordination)
what are tthe 3 special consideration to exercise for strtoke
Reduced motor control (weakness or paralysis) on one side of the body
Sensation may be impaired (implications for stretching)
Intolerance to high intensity exercises (↓VO2 max capacities)
