Summary
Stroke outcomes improved for Mexican Americans (MA) but not non-Hispanic Whites (NHW) between 2008-2019. By 2019, no significant race-ethnic differences in stroke outcome trends were observed.
Area of Science:
- Neurology
- Public Health
- Health Disparities
Background:
- Stroke outcomes and trends by race-ethnicity are critical for understanding health disparities.
- Previous research indicates varying stroke outcomes across different racial and ethnic groups.
Purpose of the Study:
- To quantify trends in stroke outcomes from 2008 to 2019 stratified by race-ethnicity.
- To identify if race-ethnicity influences the trajectory of stroke recovery and long-term outcomes.
Main Methods:
- A population-based cohort of ischemic stroke patients was studied.
- Outcomes were assessed via interviews at 90 days post-stroke.
- Linear regression with multiple imputation and inverse probability weighting was employed to model trends.
Main Results:
- While quality of life trends remained stable across groups, neurologic outcomes improved significantly for Mexican American (MA) individuals.
- Functional outcomes showed improvement trends in MA stroke patients, contrasting with stable trends in non-Hispanic White (NHW) patients.
- Cognitive outcomes demonstrated a complex pattern for MA patients (improvement-decline-improvement) and stability for NHW patients, with no significant race-ethnic differences in overall trends by 2019.
Conclusions:
- Stroke outcome improvements were observed in MA individuals but not in NHW individuals during the study period.
- Despite initial differences, significant race-ethnic disparities in stroke outcome trends were not evident by 2019.
- Investigating factors driving positive trends in MA populations may offer insights for enhancing stroke care universally.

01:29Stroke: Introduction and Types
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
