Long-Term Effects of Secondary Prevention on Cognitive Function in Stroke Patients

Abstract

Background-Limited long-term follow-up data exist on the impact of appropriate secondary prevention therapies on cognitive function in patients after first-ever stroke. The aim of this study is to determine the effect of secondary prevention of vascular events on cognitive function after stroke. Methods and Results-Data were collected between 1995 and 2011 (n=4413) from the community-based South London Stroke Register covering an inner-city multiethnic source population of 271 817 inhabitants. Modified Poisson regression models were constructed to adjust for cognitive function status at 3 months, demographic and socioeconomic characteristics, case mix, stroke subtype, vascular risk factors, disability, and stroke recurrence. In patients with ischemic strokes without a history of atrial fibrillation (AF), there was a reduced risk of cognitive impairment associated with the use of different prevention treatments: (1)

Functional Disability and Cognitive Impairment After Hospitalization for Myocardial Infarction and Stroke

“…10, 16, 46 Conversely, vascular risk factor modification may reduce the long-term risk of cognitive impairment after stroke. 47 Research is needed to better elucidate the mechanisms and risk factors for functional decline over the long-term after MI or stroke.…”

Cognitive Impairment, Vulnerability, and Mortality Post Ischemic Stroke: A Five-Year Follow-Up of the Action on Secondary Prevention Interventions and Rehabilitation in Stroke (ASPIRE-S) Cohort

“…Control of vascular risk factors has been shown to reduce both mortality as well as the rate of cognitive decline post stroke (37), suggesting that by controlling secondary risks, both the rate of cognitive decline and mortality rates post-stroke may be reduced.…”

“…It is becoming increasingly recognized that traditional cardiovascular risk factors are not only risk factors for coronary and cerebrovascular events, but also for dementia [23,24]. Triglyceride rich lipoproteins in particular are associated with small vessel cerebrovascular disease [25].…”
