A Cerebrovascular Accident (CVA), often called a Stroke, is a multifaceted neurological disorder resulting from a brain lesion.
CVA Causes: What Leads to a Stroke?
Understanding the causes of CVA is crucial for prevention and treatment:
- Ischemic Stroke: Occurs when an embolism blocks blood flow, causing oxygen deprivation.
- Hemorrhagic Stroke: Involves bleeding in the brain due to a burst vessel.
- Transient Ischemic Attack (TIA): A temporary interruption of blood flow, often a warning sign of a larger ischemic stroke.
Risk factors can be modifiable or non-modifiable, with common ones including hypertension and smoking. (Learn more about these categories and preventative strategies in our full content.)
CVA Locations: Mapping Stroke Symptoms
The impact of a CVA varies based on the artery affected:
- Internal Carotid Artery: Key artery to the brain; symptoms can include hemiplegia and aphasia.
- Middle Cerebral Artery: The most common stroke location, affecting the frontal, temporal, and parietal lobes.
- Anterior Cerebral Artery: Linked to lower extremity weakness and cognitive changes.
- Posterior Cerebral Artery: Affects the occipital lobes and brainstem, causing diverse symptoms.
In-depth scenarios and case studies highlight real-world symptom presentations. (Access our full guide for detailed symptom analysis.)
Occupational Therapy Evaluation for CVA
Effective OT evaluation is patient-centered, focusing on:
- Recipients defining personal goals.
- Assessment tools like the Canadian Occupational Performance Measure and the NIH Stroke Scale.
- Tools and evaluations tailored to assess the impact on BADLs and IADLs, including standardized tests like AMPS.
These assessments are critical for developing targeted rehab strategies. (Explore our complete content for evaluation tool comparisons.)
Interactive Treatment Considerations
Seated Occupations: Address postural control and environmental interactions.
Standing Occupations: Focus on weight distribution and postural strategies.
Language Use: Tackle aphasia with communication adaptations.
Upper Extremity Usage: Use therapeutic exercises and constraint-induced movement therapy.
Key action: Engage in task-specific activities using adapted equipment. (Check out our full content for video examples and treatment plans.)
Medical Management – Important Actions
Medical intervention varies with stroke type and requires quick action to prevent complications like DVT and pneumonia. Monitoring and early rehab within the first 3-6 months are crucial for recovery.

What are the main types of cerebrovascular accidents (strokes)?
The main types of cerebrovascular accidents (CVAs) include ischemic strokes, which occur when an embolism blocks blood flow, hemorrhagic strokes, caused by bleeding in the brain due to a burst vessel, and transient ischemic attacks (TIAs), which are temporary interruptions of blood flow often acting as a warning sign for a larger ischemic stroke.
Which arteries are commonly affected in strokes and what symptoms do they cause?
The common arteries affected during strokes are the internal carotid artery, leading to symptoms like hemiplegia and aphasia; the middle cerebral artery, the most common stroke location, affecting the frontal, temporal, and parietal lobes; the anterior cerebral artery, associated with lower extremity weakness and cognitive changes; and the posterior cerebral artery, affecting the occipital lobes and brainstem, resulting in diverse symptoms.
How does occupational therapy evaluate patients after a CVA?
Occupational therapy (OT) evaluation for CVA is patient-centered, using tools like the Canadian Occupational Performance Measure and the NIH Stroke Scale. OT assessments focus on personal goals, the impact on basic and instrumental activities of daily living, and employ standardized tests like the Assessment of Motor and Process Skills (AMPS) to develop targeted rehabilitation strategies.
What are important treatment considerations for stroke survivors?
Key treatment considerations for stroke survivors include addressing postural control and environmental interaction during seated occupations, focusing on weight distribution and postural strategies in standing occupations, using communication adaptations for aphasia, and employing therapeutic exercises along with constraint-induced movement therapy for upper extremity usage.
What are critical medical management steps needed after a stroke?
Critical medical management steps after a stroke include quick intervention tailored to the type of stroke to prevent complications such as deep vein thrombosis (DVT) and pneumonia. Monitoring and starting early rehabilitation within the first 3-6 months is crucial for optimal recovery.
