Recovery from stroke time course |
Early (first 3 months)- spontaneous quick recovery
6-7 months- things slow down Late- slower but still some recovery, variability |
|
|
Changes in diagnosis over time |
global to nonfluent (i guess a non-global nonfluent) Wernicke's to nonfluent less severe changes more than severe -younger patients evolve more into Broca's |
|
|
More patients improve in... |
comprehension than production verbal than written |
|
|
Contributing factors to spontaneous recovery (neural mechanisms of recovery) |
-adema- brain swells less -absorption of damaged tissue -blood flow returning |
|
|
diaschisis |
decreased brain function at a distance from the lesion (synapsis disconnected) |
|
|
regenerative or collateral sprouting |
dendrites look for healthy neurons to connect to |
|
|
Neuroplasticity |
adaptive capacity of the brain |
|
|
Factors leading to increased plasticity |
-repetition -intensity -timing -exposure to training -specificity- nature fo trainig -salience- making things rewarding -age- (younger better) -transference (one type of skill helpful to others) -interference (compensatory strategies could interfere) |
|
|
Do site and size make a difference? |
site- yes (localizationist) size- in general yes but not necessarily |
|
|
controversial factors affecting recovery |
age- younger better gender- not really w aphasia handedness- L handed may have bilateral distribution of language but not conclusive psychosocial- depression has an effect |
|
|
Approaches to research |
case studies-individuals group studies- control and experimental groups Frequency of occurence data- counting behaviors etc. Pre vs post treatment single subject- 1 person, baseline, therapy, check maintenance |
|
|
efficacy
|
potential for positively changing a target pop
|
|
|
effectiveness
|
changes brought about by treatment in clinical process
