Definition and Terminology of Cerebrovascular Accident (CVA) and Stroke
Cerebrovascular accident (CVA) is a term historically used to describe what is now more commonly referred to as "stroke." The term CVA is considered outdated because it suggests that stroke is an accident, rather than a preventable and treatable medical condition. Recent research shows a decline in the use of "CVA" in scientific literature, with experts recommending the use of more precise and diagnostic terms like "stroke" to avoid confusion and improve clarity in both clinical and research settings .
Epidemiology and Risk Factors for CVA (Stroke)
CVA is a leading cause of death and disability worldwide, with significant impacts in both high- and low-income countries Rauniyar2023Sriyono2023. Major risk factors for CVA include hypertension, diabetes, obesity, hyperlipidemia, smoking, and alcohol use Rauniyar2023Masri2024. In specific populations, such as those with sickle cell disease or congenital heart disease, the risk of CVA is much higher than in the general population, and these patients may experience strokes at a younger age Hoffmann2010Ohene‐Frempong1998. In sickle cell disease, risk factors for infarctive stroke include prior transient ischemic attack, low hemoglobin, acute chest syndrome, and high blood pressure, while hemorrhagic stroke is linked to low hemoglobin and high leukocyte count .
Types and Clinical Presentation of CVA
CVA can be classified into two main types: ischemic (caused by blockage of blood flow) and hemorrhagic (caused by bleeding in the brain) Rauniyar2023Moon2016Ohene‐Frempong1998. Ischemic strokes are more common, while hemorrhagic strokes tend to have higher early mortality rates . Symptoms depend on the area of the brain affected but often include sudden weakness, difficulty speaking, vision problems, and loss of coordination Rauniyar2023Prayitno2025. In clinical practice, rapid and accurate diagnosis is essential, as some conditions can mimic CVA, such as brain tumors, seizures, or metabolic disturbances .
Special Populations: CVA in Congenital Heart Disease and Sickle Cell Disease
Adults with congenital heart disease have a higher risk of CVA compared to the general population, especially those with cyanotic lesions or mechanical heart valves . In sickle cell disease, both children and adults are at increased risk for both ischemic and hemorrhagic strokes, with significant morbidity and mortality .
CVA and COVID-19
Recent studies have shown that COVID-19 infection can increase the risk of ischemic CVA, adding to the complexity of stroke management during the pandemic .
Management and Treatment Approaches
Standard management of CVA includes rapid diagnosis, stabilization, and treatment to restore blood flow or control bleeding, depending on the type of stroke . In some regions and traditions, alternative therapies such as Panchakarma from Ayurveda have been explored, with some case reports suggesting potential benefits in rehabilitation and symptom management . Family nursing care and education are also important for improving outcomes and supporting recovery .
Emerging Therapies: Stem Cell Transplantation
Stem cell transplantation is an area of active research for CVA, with studies focusing on the potential for neuroprotection and recovery after stroke. Most research has been conducted in high-income countries, with a shift from laboratory to clinical studies in recent years. Mesenchymal stem cells are the most commonly studied, but more research is needed to establish their effectiveness and safety .
Conclusion
Cerebrovascular accident, or stroke, remains a major global health challenge with significant morbidity and mortality. The terminology is shifting towards more precise language, and risk factors are well established, including hypertension, diabetes, and specific genetic conditions. Rapid diagnosis and treatment are critical, and new therapies such as stem cell transplantation are being explored. Continued research and education are essential to improve prevention, management, and outcomes for patients with CVA.
