Stroke
What is Stroke?
CT
MRI
X-Ray
Tests for Stroke
Treatment
Treatment of stroke depends on what type of stroke it is.
HEMMORHAGIC
or
ISCHEMIC
An ischemic stroke or TIA occurs if an artery that supplies oxygen-rich blood to the brain becomes blocked. Often, blood clots cause the blockages that lead to ischemic strokes and TIAs.
tPA
DWI SCAN
PWI SCAN
Diffusion Weighted MRI
Perfusion Weighted MRI
How does tPA work?
Fibrinolytic agent
tPA and plasminogen bind to the clot
This process changes plasminogen to plasmin, and the clot dissolves.
Your doctor will administer
This medicine called tissue plasminogen activator (tPA) can break up blood clots in the arteries of the brain
If you have an
ischemic
stroke...
If you have a hemorhagic stroke, your doctor WILL NOT use tPA because it will make the bleeding worse.
If you have a
hemorrhagic
stroke...
the most common treatments include surgery.
the type of surgery depends on the type of hemorrhage.
AVM : arteriovenous malformations
Cerebral Aneurysm
weak blood vessel
tangle of arteries and veins easily ruptured
Medications for Stroke...
The sudden death of brain cells in a localized area due to inadequate blood flow.
Occurs when the arterial blood flow leading to, or in the brain becomes blocked or ruptures.
Lack of Blood Flow to the Brain...
When blood flow to the brain is compromised, blood can no longer provide the brain with adequate oxygen and nutrients. Therefore, the neurons, (nerve cells) are subject to death. This results in a decreased ability of the body to function properly.
Statistics
More than 1/2 million people in the U.S. experience a new or recurrent stroke each year.
Stroke is the 3rd leading cause of death in the U.S.
Stroke is the leading cause of disability
3 million Americans are currently and permanently disabled from stroke.
Stroke may cause...
paralysis : loss of muscle function or sensation
speech impairment
loss of memory
loss of reasoning ability
coma : unconsciousness for an extended period of time
death
stroke is an EMERGENCY and a PRIORITY
quicker initiation of treatment usually brings better results.
treatment involves destroying the clot within 3 hours.
Symptoms
Weakness of face or extremities
Difficulty speaking
Difficulty seeing
Dizziness
TIA : transient ischemic attack
Risk Factors
age --> risk increases slightly over age 55
gender --> males are slightly more at risk
race --> American blacks have a higher risk
Carotid Doppler
Transcranial Doppler
MRA (magnetic resonance
angiogram)
Cerebral Arteriogram
Urinalysis
Pulse Oximetry
Blood work
Blood lipids
Coagulation tests
Blood chemistry tests
Electroencephalogram
Lumbar Puncture
Head and Skull
Blood Vessels
Lab Tests
Other Tests
CT Scan
The most important test for stroke.
Most commonly used to detect stroke in Emergency rooms.
Shows many tissues, and can show areas of ischemia in the brain.
Cerebral Angiogram
Another common diagnostic test.
Used to map blood vessels in the
bra
in
Gives us

he ability to see bloc
