Overview
Ischemic vascular dementia (IVD) results from multiple small vessel strokes or large vessel disease leading to cognitive impairment and functional decline. It is a significant contributor to dementia cases, often seen in elderly patients with underlying vascular risk factors 1.Diagnosis
Clinical Presentation: Cognitive decline, focal neurological deficits, and history of vascular events 1.
Neuroimaging: MRI or CT scans may show white matter changes, lacunar infarcts, or cortical microinfarcts 1.
Cerebrovascular Risk Factors: Assessment for hypertension, diabetes, hyperlipidemia, and prior strokes 1.
Cognitive Testing: Use of standardized neuropsychological tests to evaluate cognitive domains 1.Management
Risk Factor Modification: Control of hypertension, diabetes, and hyperlipidemia 1.
Antiplatelet Therapy: Aspirin or other antiplatelet agents to prevent further vascular events 1.
Lifestyle Modifications: Encourage smoking cessation, physical activity, and healthy diet 1.
Secondary Prevention: Management of cardiovascular risk factors to reduce recurrent stroke risk 1.Special Populations
Elderly: Preoperative IVD significantly impacts long-term mortality in elderly patients undergoing emergency abdominal surgery (HR 1.10, 8-year mortality) 1.Key Recommendations
Screen for and manage cerebrovascular risk factors in patients with suspected IVD to reduce long-term mortality (Evidence: Moderate 1).
Initiate antiplatelet therapy for secondary prevention in patients with IVD to prevent recurrent vascular events (Evidence: Moderate 1).
Prioritize comprehensive geriatric assessment in elderly patients with IVD, especially before major surgeries, due to increased mortality risk (Evidence: Moderate 1).References
