The aim of this study was to present the prevalence of stroke from a pilot study in old people. The urban site sample (Madrid) was made up of 397 subjects and the rural site sample (Arévalo, Avila) of 862 subjects. The study was performed with a door-to-door methodology. In the urban sample, the prevalence of stroke was 8.5% (CI 95% = 5.5-11.5%) and that of TIA was 2.1% (CI 95% = 0.6-3.6%). In the rural location the prevalence of stroke was 7.1% (CI 95% = 5.4-8.8%). This prevalence of stroke is higher than in other Spanish studies. These results need to be confirmed in a wider investigation.

Background: Accurate distinction between stroke etiologic subtypes is critical for physicians to provide tailored treatment. The triglyceride-glucose (TyG) index, a marker of insulin resistance, has been associated with stroke risk but its role in distinguishing stroke etiologic subtypes remains unclear. We aimed to assess the TyG index's ability to differentiate cardioembolic (CE) from non-cardioembolic (NCE) strokes.

Background: Ischemic stroke is a prevalent and life-threatening cerebrovascular disease that is challenging to treat and associated with a poor prognosis. Astragaloside IV (AS-IV), a primary bioactive component of Astragali radix, has demonstrated neuroprotective benefits in previous studies. This study aimed to explore the mechanisms through which AS-IV may treat cerebral ischemia-reperfusion injury (CIRI).

Background: Body mass index (BMI) consistently correlates with the triglyceride-glucose (TyG) index, a marker of insulin resistance, which in turn is linked to heightened cardiovascular disease (CVD) risk. Thus, insulin resistance could potentially mediate the association between BMI and CVD risk. However, few studies have explored this mechanism in the general population.

Background: Post-stroke depression (PSD) is the most prevalent neuropsychiatric complication following a stroke. The inflammatory theory suggests that PSD may be associated with an overactive inflammatory response. However, research findings regarding inflammation-related indicators in PSD remain inconsistent and elusive.
