1. etiologies
2. typical course
3. type/characteristics of speech problems

Answer 1

1. stroke, TBI
2. sudden onset, neurologic recovery, stabilization
   3, vary greatly depending on site of lesiona and extent of neurological damage

Question 2

Acute CNS injuries:

1. what kind of events are they
2. what are the effects (4)
3. what is the last effect?

Answer 2

1. ischemic
2. a. edema
   b. decreased in cerebral blood flow
   c. abnormal release of neurotransmitters for a few weeks
   d. diaschisis
3. diaschisis: If A & B are connected. Damage in A=problems with function in B (think of referred pain)

Question 3

Spontaneous Recovery Following Acute CNS Injury

Answer 3

Different patterns for different types of stroke and for TBI

Question 4

Causes of acute CNS dysfunction
types
breakdown further part 1, and which is more common

Answer 4

stroke can be ischemic (80%) or hemorrhagic

Question 5

Occlusive/Ischemic CVA

1. What is it?
2. what is ischemia?
3. What is an infarct?
4. What are the 2 main types of occlusive CVA? What is the main difference?

Answer 5

1. artery is blocked, blood supply to brain is cut off
2. local/temporary loss of blood supply due to obtrsuction of the circulation to a part. Ischemia is reversible
3. Death of tissue as a result of ischemia
4. thrombotic and embolic . Where the block comes from

Question 6

Thrombolic CVA (TCVA)

1. Where does block come from
2. What might precede it?
3. What are symptoms of these?
4. What are txs?

Answer 6

1. Plug of material (fatty deposits, fibrous material) arises at site of blockage
2. warning signs i.e. TIAs (transient ischemic attacks)
3. numbness/weakness one side of body, transient speech/L probs, transient vision loss
