Stroke prevention encompasses primordial, primary, secondary, and tertiary strategies, with recent advances including social determinants of health in risk algorithms, long-term atrial fibrillation monitoring, remote blood pressure monitoring, and GLP-1 receptor agonists, all of which may also preserve brain health and reduce cognitive decline.
Key Findings
Results
New stroke risk prediction algorithms have been developed that incorporate social determinants of health, remove racial biases, and include cardiometabolic and kidney disease factors.
These newly developed and validated algorithms represent an advance over prior clinical risk prediction tools
Prior tools incorporated demographic, lifestyle, and health factors but lacked social determinants of health
The inclusion of cardiometabolic and kidney disease represents an expansion of traditional cardiovascular risk factor frameworks
Removal of racial biases from prediction algorithms is highlighted as a specific improvement in newer tools
Results
Long-term monitoring for atrial fibrillation is identified as a recent development that may reduce disparities in stroke risk.
Long-term atrial fibrillation monitoring is grouped with other recent developments as a strategy for secondary stroke prevention
Detection of atrial fibrillation is framed within the context of accounting for presumed causal mechanisms of stroke
This approach is noted as potentially reducing disparities in risk alongside remote blood pressure monitoring and GLP-1 receptor agonists
Results
Remote patient monitoring of blood pressure is identified as a recent development in stroke prevention that may help reduce health disparities.
Remote blood pressure monitoring is listed among recent developments in secondary stroke prevention
It is specifically noted as one strategy that 'may reduce disparities in risk'
This approach is positioned alongside long-term atrial fibrillation monitoring and GLP-1 receptor agonists as emerging tools
Results
Glucagon-like peptide-1 (GLP-1) receptor agonists are identified as an emerging pharmacological tool in stroke prevention that may reduce disparities in risk.
GLP-1 receptor agonists are described as part of 'increased use' in the context of stroke prevention
They are listed among 'recent developments that may reduce disparities in risk'
Their role is framed within secondary stroke prevention and vascular risk factor management
Results
Secondary stroke prevention increasingly accounts for presumed causal mechanisms of stroke while managing risk factors.
This mechanistic approach to secondary prevention is described as an evolving standard in stroke care
The approach involves identifying the likely cause of a stroke to guide specific preventive strategies
Risk factor management remains a concurrent component alongside mechanism-based treatment
Results
Vascular risk factor control before and after stroke may help mitigate cognitive decline and dementia by preserving brain health.
The article frames stroke prevention as directly linked to broader brain health preservation
Efforts to prevent stroke are stated to also reduce risk of 'cognitive decline, dementia, and late-life depression'
The relationship between stroke prevention and brain health is described as applicable both before and after stroke occurs
Results
Social and environmental determinants of health are increasingly recognized as contributors to stroke risk and may be amenable to policy and population-level solutions.
The article refers to these factors as 'social and environmental determinants, or drivers, of health'
They are described as 'increasingly recognized contributors to stroke risk'
Policy and population-level interventions are identified as potential approaches to address these determinants
Results
Primary stroke prevention is described as primarily falling to primary care physicians, with neurologists playing a role particularly for patients with incidentally discovered cerebral infarcts.
Neurologists may be involved when patients present for other reasons or are 'incidentally discovered to have cerebral infarcts in the course of evaluation for other conditions'
This delineation of clinical responsibility reflects the population-level nature of primary prevention
The article distinguishes among primordial, primary, secondary, and tertiary prevention as distinct categories
What This Means
This review article summarizes the current state of stroke prevention across four levels: primordial prevention (stopping risk factors from developing in the first place), primary prevention (preventing a first stroke), secondary prevention (preventing recurrence after a stroke), and tertiary prevention (reducing disability after stroke has occurred). Recent progress includes the development of better tools to predict who is at risk for stroke — tools that now factor in social conditions like poverty and housing, avoid racial biases built into older models, and account for kidney and metabolic diseases. The article also highlights newer technologies and medications, including devices that monitor heart rhythm over long periods to detect atrial fibrillation, home blood pressure monitors that transmit data to doctors remotely, and a newer class of diabetes and weight-loss drugs called GLP-1 receptor agonists, all of which may help lower stroke risk and reduce health disparities between different populations.
This research suggests that preventing stroke is not just about treating individual risk factors like high blood pressure or high cholesterol, but also about addressing the broader social and environmental conditions that shape people's health over a lifetime. The article emphasizes that where someone lives, their access to healthy food, and their socioeconomic conditions all influence stroke risk and should be considered in both clinical care and public health policy. Importantly, controlling vascular risk factors appears to benefit not only stroke prevention but also long-term brain health, potentially reducing the risk of memory loss, dementia, and late-life depression — suggesting that efforts invested in stroke prevention may have broad benefits for aging populations.
