Factors influencing recovery

Question 1

Anosognosia

Answer 1

lack of awareness or recognition of dysfunction

Question 2

patients with bilateral lesions show ________ recovery than patients with unilateral lesions

Answer 2

less

Question 3

edema

Answer 3

swelling in brain; secondary effect
i.e. after stroke (affecting healthy tissue not damaged by stroke)

Question 4

restitution vs. substitution

Answer 4

recovery may not represent true restitution of function, but substitution of a new behaviour (and possibly brain region)

Question 5

Diaschisis

Answer 5

secondary effect; brain lesion in one area can affect another area if it has strong connection to it. recovery can occur in spontaneous reduction of diaschisis (metabolic depression)

Question 6

predictors of recovery

Answer 6

rich environment, social network

Question 7

Compensatory strategies

Answer 7

a patient learns strategies to adapt to new motor, sensory or cognitive impairments

Question 8

Answer 8

reserve: less firing, more weakly connected, but is more plastic.

Question 9

“Rich club” of neurons

Answer 9

the ones used the most; highly connected, active

Question 10

restitution is only possible…

Answer 10

for secondary effects

Question 11

recovery plateau

Answer 11

idea that there is a limit to recovery; 1st year is considered the critical period (and plateau after)
