CVA

Question 1

What is CVA?

Answer 1

Cerebellar vascular accident
-An acute neurologic dysfunction of vascular origin with symptoms and signs corresponding to the involvement of focal areas of the brain

Question 2

Vascular damage to the brain disrupts blood flow and oxygen supply to surrounding cells leading to

Answer 2

brain tissue death or infarction

Question 3

Symptoms and diagnosis for stroke are determined by

Answer 3

MLE
mechanism- cause or type of stroke
location-part of brain
extent of lesion-severity of stroke

Question 4

Mechanism=

Answer 4

cause of stroke

Question 5

Location

Answer 5

part of brain

Question 6

Extent of lesion

Answer 6

severity of stroke

Question 7

Vascular means

Answer 7

loss of blood to the brain

Question 8

What does Ischemic mean

Answer 8

Obstruct of blood flow

• Results from blockage of blood vessel
• Thrombosis
• embolism

Question 9

Ischemic=

Answer 9

Results from blockage of blood vessel

Question 10

Thrombosis

Answer 10

Stenosis or occlusion

Question 11

Embolism

Answer 11

Dislodged platelets, cholesterol, platelets, or other material that travel in bloodstream and blocks a vessel

Question 12

Hemorrhagic

Answer 12

bleeding in different parts of the brain

Question 13

What does hemorrhagic result from

Answer 13

rupture of blood vessels

• hypertension- cocaine and drug use
• arteriovenous malformation- aneurysm
• intracerebral
• subarachnoid

Question 14

AVM=

Answer 14

abnormal connection between artery and veins

Question 15

Transient Ischemic Attacks

Answer 15

Similar to stroke

-difference is that TIA blockage is temporary

Question 16

Symptoms of TIA’s

Answer 16

• sudden numbness, or weakness of the face, arm, or leg especially in one side of the body
• sudden confusion, trouble speaking or understanding
• sudden trouble seeing in one eye or both eyes
• sudden trouble walking, dizziness loss of balance or coordination

Question 17

Diagnostic workup->

Answer 17

• Obtain History
• Brief neuro exam
• CT scan
• MRI scan

Question 18

Diagnostic workups: Radiology

Answer 18

• CT
• MRI
• PET

Question 19

CT-Gross assessment- do it fast/rapidly

Answer 19

• shows abnormalities of the brain

- can help determine if these areas were caused by insufficient blood flow

Question 20

Magnetic resonance imaging (MRI)- Get a more accurate picture

Answer 20

-produces very accurate pictures of the brain and its arteries and can usually determine the area of the brain that is damages by an ischemic stroke

Question 21

Positron emission tomography- chemical activity

Answer 21

uses radioactive material that is injected into the body to pinpoint areas of the brain with the greatest chemical activity. After the radioactive material is injected, the scanning machine reads how much energy is emitted from the brain, and creates a picture of the brain from that reading. PET is helpful in determining the extent of damage to the brain

Question 22

Acute stroke care->

Answer 22

• determining cause and site of stroke
• preventing progression of stroke
• restoration of blood flow and limitation of neuronal damage for ischemic stroke
• control of intracranial pressure, preventing re-bleeding, maintenance of cerebral perfusion, and control of vasospasm for hemorrhagic stroke
• reducing cerebral edema
• preventing secondary medical complications
• treating acute neurological symptoms

Question 23

Recovery from stroke->

Answer 23

• varies with nature and severity of the initial injury
• spontaneous recovery
• neuroplasticity- relearning to do things
• neurological and functional recovery
