-CSF
CSF 10%
what hapens to the brain when a stroke occurs - Answers - there is a blockage in the
circle of will
look at picture - Answers - locate medulla
look at brain - Answers - locate lobs
What are Manifestations of Neurologic Damage - Answers - Altered level of
consciousness (LOC)
Motor Dysfunction
Sensory Deficits
Visual Loss
Language Disorders
Seizures
Note ; Expanding lesions (ie: growing tumor or hemorrhage) cause additional
impairment as the adjacent areas become involved.
what is stroke ? - Answers - Acute stroke is a sudden loss of brain function that occurs
when the blood flow supplying oxygen to a part of the brain is interrupted.
A stroke deprives the neurons and other brain cells of glucose and oxygen, which leads
to cell death.( a stroke takes away glucose and oxygen which leads to cell death)
Stroke Statistics Canada - Answers - (slide 9)
Mortality and Morbidity - Answers - - 20% of stroke patients die within first 2 days
- Huge burden of disease for many of those who survive
- 10% almost complete recovery
- 25% minor impairment
- 40% moderate to severe impairment
, - Most improvements occur in first 3 months
what are some risk factors of stroke ? - Answers - - Diabetes
- Hypertension
- Systemic lupus erythematosus (SLE)
- Hypercholesterolemia
- Hyperlipidemia
- Atherosclerosis
- History (Hx) of Transient Ischemic Attacks (TIA)
check slide 12 for more risk factors
what are the two types of strokes ? - Answers - ischemic and hemorrhagic
what is an ischemic stroke ? - Answers - Occlusion of a cerebral blood vessel (5
minutes of ischemia causes irreversible nerve cell damage.)
occurs when blood clots or other particles block the blood vessels to the brain.
What is an hemorrhagic stroke? - Answers - Rupture of cerebral vessel
A stroke that leads to hemorrhage (too much blood in the brain)
What is a CVA? - Answers - A stroke or CVA(cerebral vascular accident) is an
infarction of brain tissue that results from lack of blood.
what is the Pathophysiology of a stroke ? - Answers - -Area of necrosis (as a result of
infarction)
-Surrounding area of inflammation
-of function in these areas
-Necrotic tissue liquefies and leaves a cavity in the brain
what are the two types of Ischemic Stroke (2 types) - Answers - 1. Thrombotic
(Atheroma)
2. Embolic
what are the two types of Hemorrhagic Stroke(2 types) - Answers - 1. Intracerebral
hemorrhage (ICH)
2. Sub-Arachnoid hemorrhage (SAH)
