Introduction

Cerebrovascular diseases, which encompass a range of disorders affecting the blood vessels in the brain, are among the leading causes of morbidity and mortality worldwide. The timely and accurate diagnosis of these conditions is crucial for effective treatment and improved patient outcomes. Neuroimaging has long been a cornerstone in the diagnosis and monitoring of cerebrovascular diseases and recent advances in this field have significantly enhanced our ability to detect, assess and manage these disorders [1]. Historically, the most commonly used neuroimaging techniques for cerebrovascular disease have been computed tomography and magnetic resonance imaging. CT scans are widely accessible and effective in identifying acute hemorrhages, while MRI provides superior contrast resolution, allowing for detailed visualization of brain structures and early detection of ischemic strokes. These modalities have been instrumental in guiding acute stroke management, particularly in determining eligibility for thrombolytic therapy. In recent years, advancements in MRI technology have led to the development of more sophisticated techniques that provide deeper insights into cerebrovascular pathology. Diffusion-weighted imaging is one such advancement, offering high sensitivity in detecting acute ischemic stroke within minutes of symptom onset. DWI is now a standard tool in stroke imaging, allowing for rapid and accurate identification of ischemic areas and guiding acute intervention [2].

Description

Functional MRI (FMRI) has traditionally been used to study brain activity by measuring changes in blood oxygenation levels. However, its application has expanded to cerebrovascular disease, particularly in evaluating the hemodynamic impact of vascular stenosis or occlusion. FMRI can provide insights into the brain's functional reserve and predict the risk of future ischemic events. Vessel wall imaging, a newer technique, focuses on the direct visualization of the vessel wall rather than the lumen, offering detailed insights into the pathology of intracranial atherosclerosis and vasculitis. This approach allows for the detection of vessel wall thickening, inflammation and plaque characteristics, which are often not visible on conventional lumenbased imaging. Vessel wall imaging is emerging as a valuable tool in the diagnosis and management of intracranial vascular diseases [3].

AI-powered tools are also being used to predict patient outcomes, optimize treatment strategies and monitor disease progression. For example, ML algorithms can analyze perfusion imaging data to predict the likelihood of infarct growth and guide treatment decisions. As these technologies continue to evolve, they hold the potential to further improve the accuracy, efficiency and personalization of cerebrovascular disease management. The advances are have significantly improved our ability to detect and manage these conditions. From advanced MRI techniques to AI-powered tools, these innovations are enhancing the precision and speed of diagnosis, guiding more effective treatments and ultimately improving patient outcomes. As research continues, we can expect even more groundbreaking developments in the neuroimaging field, further advancing the care of patients with cerebrovascular diseases [4,5].

Public health campaigns should also emphasize the importance of managing chronic conditions like hypertension and diabetes, particularly in women, to reduce the long-term risk of cerebrovascular diseases. Improving the early detection of stroke in women requires better education for both the public and healthcare providers about the non-traditional symptoms that women may experience. Telemedicine and other digital health tools could play a role in facilitating earlier diagnosis, particularly in underserved areas where access to care may be limited. Gender-specific treatment protocols should be developed to ensure that both men and women receive appropriate and timely care. This includes addressing potential biases in the use of diagnostic imaging and ensuring equitable access to life-saving treatments like thrombolysis and mechanical thrombectomy.

Conclusion

Rehabilitation services must be adapted to meet the unique needs of men and women. For women, this might involve a greater focus on mental health support and social integration, while for men, it might involve strategies to reduce the risk of recurrent strokes through lifestyle modifications and adherence to secondary prevention measures. Long-term care strategies should also consider the social and economic factors that affect recovery. Women, who are more likely to be single or widowed in older age, may need additional support to access rehabilitation services and maintain independence. Gender differences in cerebrovascular disease risk, presentation and outcomes are significant and warrant attention in both clinical practice and public health policy. By recognizing and addressing these differences, healthcare providers can offer more effective, equitable care, ultimately improving outcomes for all patients affected by cerebrovascular diseases. Future research should continue to explore these gender differences to inform the development of more personalized and gender-sensitive interventions.
