Study Notes
Cardiovascular Accident (CVA)
- CVA is an acute vascular dysfunction with symptoms and signs corresponding to the involvement of focal areas in the brain.
- Results in upper motor neuron dysfunction (hemiplegia).
- The neurologic deficits must persist longer than 24 hours to be labeled as CVA.
- Accompanying dysfunctions include sensory disturbances, cognitive/perceptual dysfunction, visual disturbances, personality changes/intellectual changes and associated language disorders.
Objectives
- Break CVA myths
- Define CVA
- Differentiate CVA and stroke from heatstroke
- Know the signs and symptoms of CVA
- Understand medical treatment
- Understand the role of occupational therapy (OT) in treatment
Types of CVAs
- Hemorrhagic: Rupture in a weakened blood vessel in the brain.
-
Ischemic: Insufficient blood flow to the brain, anoxia in brain cells.
- Atherosclerosis: Narrowed or blocked arteries.
- Embolic: Blood clot travels and blocks a brain artery.
- Transient Ischemic Attacks (TIAs): Temporary blockage of blood flow to brain (warning signs for a stroke).
Etiology (Causes of CVA)
- Non-modifiable risk factors: Age (even young people!), gender, race, ethnicity, heredity.
- Modifiable risk factors: Hypertension, cardiac diseases, diabetes, cigarette smoking, excessive alcohol use, illegal drug use, and lifestyle factors (e.g. obesity, physical inactivity, diet, stress).
Clinical Features and Problem Areas
- Specific locations affected (Internal carotid artery, Middle cerebral artery, Anterior cerebral artery, Posterior cerebral artery, Cerebellar artery system, Vertebrobasilar artery system)
- Possible impairments (depending on the affected area).
Medical Management
- Medical treatment is specific based on type/location of vascular lesion, severity, other medical/neurological problems.
- Early medical treatments.
- Prevention of complications (e.g. deep vein thrombosis - DVT, pulmonary embolism, pneumonia, cardiac disease).
- Client evaluation and therapist intervention is based on the medical record to help clients to adapt to their current needs.
- Neurological recovery takes time (often up to 6 months).
Aphasia
- Aphasia is an acquired communication disorder that is caused by brain damage. Types include:
- Global Aphasia: Loss of all language skills.
- Broca's Aphasia: Difficulty producing speech and in grammatical aspects of language.
- Wernicke's Aphasia: Difficulty understanding spoken language and in word finding.
- Anomic Aphasia: Difficulty retrieving words.
Dysarthria
- Articulation disorder in speech in absence of aphasia, caused by CNS dysfunction of speech musculature causing slurred, and/or thick speech.
OT Intervention
- Client-Centered Assessments: E.g. Canadian Occupational Performance Measure (COPM).
- Top-Down Approach: Evaluating role competency and meaningfulness (past, present & future roles), identifying problematic tasks and goals.
- Standardized Tools: E.g., Arnadottir Occupational Therapy Neurobehavioral Evaluation (A-ONE), Assessment of Motor and Process Skills (AMPS).
Example of Neuro-behavioral Dysfunctions (in Task Performance)
- Using a comb to brush teeth.
- Overestimating/underestimating the distance of a glass while eating.
- Trying to dress another person instead of oneself.
- Inability to find the bathroom.
- Putting socks on over sneakers.
