Stroke
• A stroke is a medical emergency in
which the blood supply to any portion
of the brain is interrupted or reduced
• Alternative names: Cerebrovascular
accident/ disease (CVA), Cerebral
infarction, Cerebral hemorrhage
3
The symptoms of a stroke are dependant
on what portion of the brain is damage
4
SIGNS & SYMPTOMS
• Paralysis or weakness in the face,
arms and/or legs
• Confusion
• Personality changes
• Sudden change in eyesight
• Decreased motor skills
• Severe headaches
5
Types of stroke
6
Ischemic Stroke
A blood vessel
becomes blocked
and the blood
supply to that part
of your brain is
blocked
7
Ischemic Stroke
8
Hemorrhagic Stroke
A small blood
vessel in the brain
becomes weak and
ruptures.
9
RISKS
• High Blood Pressure
• High Cholesterol
• Smoking
• Heart Disease
• Diabetes
• Excessive alcohol
consumption
• Family History
• Age
• Sex
• Race
• Obesity
10
Prevention
• Control high Blood Pressure
• Lower cholesterol
• Quit smoking
• Control diabetes
• Maintain healthy weight
• Exercise
• Manage stress
• Eat a healthy diet

Editor's Notes

  1. This deprives the affected area of oxygen and nutrients which causes the brain cells to die within minutes.
  2. Once the brain cells die from a lack of oxygen, the part of the body that part of the brain controls is affected through paralysis, language, motor skills, or vision. These symptoms usually persists for stroke survivors making routine daily functions extremely difficult.
  3. Especially on one side of the body. Including loss of memory, slurred speech, trouble speaking or understanding speech. Mood changes, depression or apathy (indifference). Double vision, blurred vision, partial blindness in one or both eyes, uncontrollable eye movements or eyelid drooping. Trouble walking, dizziness, loss of balance or coordination. Occurring with no known cause.
  4. There are two primary ways in which blood can be prohibited from reaching brain tissue. Ischemic strokes are the most common, between 70-80% of all strokes. Hemorrhagic strokes are usually the result of a ruptured blood vessel, aneurysm (weakened area of a blood vessel that bulges out), or arteriovenous malformation (a cluster of abnormally formed blood vessels). This is the most common type of stroke in younger people, but overall occurs approximately 20% of the time.
  5. Further broken down into where in the body this clot originally formed. Thrombotic Stroke- occurs when a clot forms in an artery that supplies blood to the brain (i.e. carotid arteries). Embolic Stroke- occurs when a clot forms in a vessel away from the brain, but travels through the bloodstream and becomes lodged in narrower brain arteries.
  6. MRI scan of a normal brain MRI scan of an acute ischemic stroke
  7. Interrupts the brain’s blood supply and if not caught can cause intracranial pressure. Further divided based on where in the brain the bleeding occurs. Intracerebral hemorrhage (ICH)- bleeding directly into brain tissue forming a pool of blood. Subarachnoid hemorrhage- bleeding into the cerebral spinal fluid of the subarachnoid space surrounding the brain. 40% mortality over 30 day period.
  8. High BP: weakens and damages blood vessels High cholesterol: increase risks of arthrosclerosis and plaque buildup in arteries.
  9. Rehabilitation is aimed at retaining the functions unaffected to compensate for the lost functions of damaged tissue.
