Neuroplasticity
What is the difference between micro-level and macro-level?
Micro-level is neuroplasticity. Macro-level is behavioral plasticity.
The brains capacity to change happens at EITHER of these levels. Can either be adaptive or maladaptive.
What is the medical term for stroke?
Cerebrovascular Accidents (CVA)
Aside from a stroke what can cause aphasia?
TBI, brain tumors, degenerative diseases, medical procedures, Sickle Cell disease
Name examples of Macro-level behavioral changes.
restoration, reorganization, compensation, habituation, restitution, substitution, and new learning
What causes a stroke?
an interruption of blood supply to the brain, usually a blood vessel burst or a blockage by a clot
What percentage of patients with primary brain tumors experience aphasia?
About 30-50%
What is the neurophysiologic level's recovery? Compensation?
Recovery: the restoration of the function within an area of the cortex that was initially lost after the injury
Compensation: occurs when a different neural tissue takes over the function lost after injury
What is the acronym to determine if someone is having a stroke and what does it stand for?
F - face
A - arms
S - speech
T - time
Name three degenerative diseases that can cause aphasia
Primary progressive aphasia, Spongiform degeneration, Alzheimer's disease, Diffuse Lewy body disease, Cruezfeldt Jacob disease, HIV
Name the 5 behavioral mechanisms of recovery.
1. restitution-restoration-reactivation
2. reorganization-reconstruction-substitution within a functional system
3. relearning
4. facilitation
5. functional substitution-functional reorganization-functional compensation
What are the two types of strokes and what is the difference between them?
Hemorrhage: burst of blood vessels
What is neoplastic aphasia?
Experiencing aphasia due to a cancer diagnosis
What are the time-dependent phases of recovery?
acute, subacute, and chronic
Where do thrombotic strokes occur most often?
In the large arteries (ACA, MCA, PCA)
How does Sickle Cell Disease lead to aphasia?
Sickled cells can clump together and block blood vessels which can lead to a clot which leads to a stroke and the stroke can lead to aphasia
