Summary
Stroke is a major global cause of death and disability, with its burden significantly increasing from 1990 to 2019. The majority of stroke cases and deaths occur in lower-income countries, highlighting a critical health disparity.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- Stroke is a leading global cause of mortality and disability, measured by disability-adjusted life-years lost (DALYs).
- The global economic impact of stroke is substantial, exceeding US$721 billion annually, representing 0.66% of global GDP.
- There has been a significant increase in stroke incidence, mortality, prevalence, and DALYs between 1990 and 2019.
Purpose of the Study:
- To present the most current global stroke statistics.
- To inform communication strategies for stakeholders regarding the global stroke burden.
- To highlight the disproportionate impact of stroke on lower-income and lower-middle-income countries (LMICs).
Main Methods:
- Data compilation and analysis from the Global Burden of Disease research group.
- Review and approval of statistics by the World Stroke Organisation (WSO) Executive Committee.
- Presentation of updated global stroke burden metrics.
Main Results:
- Stroke incidence increased by 70.0%, deaths by 43.0%, prevalent strokes by 102.0%, and DALYs by 143.0% from 1990 to 2019.
- Lower-income and lower-middle-income countries bear 86.0% of stroke deaths and 89.0% of DALYs.
- The WSO Global Stroke Fact Sheet 2022 provides a comprehensive overview of these findings.
Conclusions:
- The global burden of stroke has risen dramatically, particularly in LMICs.
- Urgent global strategies are needed to address the increasing impact of stroke.
- Accurate and updated statistics are crucial for effective stroke prevention and management initiatives.

01:27Regulation of Stroke Volume
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

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...
