Summary
Stroke incidence in Bahrain is similar to developing nations, with cerebral infarction being the most common type among nationals. Key risk factors include hypertension, diabetes, and smoking.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- Limited data exists on stroke patterns in Bahrain.
- Understanding stroke epidemiology is crucial for public health interventions.
Purpose of the Study:
- To determine stroke types, incidence rates, and risk factors in Bahrain.
- To compare stroke patterns between Bahraini nationals and expatriates.
Main Methods:
- Retrospective review of stroke patient records from a tertiary hospital (1995-1995).
- Diagnosis and typing of stroke confirmed by clinical assessment and CT scans.
- Risk factor analysis based on clinical and laboratory data.
Main Results:
- The annual stroke incidence rate was 57 per 100,000 Bahrainis.
- Cerebral infarction was the most frequent stroke type (53%) in Bahrainis, followed by cerebral hemorrhage (30%).
- Hypertension, dyslipidemia, diabetes mellitus, ischemic heart disease, and smoking were identified as common risk factors.
Conclusions:
- Stroke incidence in Bahraini nationals aligns with rates in developing countries and the Arabian Peninsula.
- Observed differences in stroke types and demographics between nationals and expatriates likely reflect Bahrain's population structure.

Stroke: Introduction and Types
69
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...

Hemorrhagic Stroke l: Introduction
34
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...

Ischemic Stroke l: Introduction
53
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.

Hemorrhagic Stroke ll: Pathophysiology
52
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...

Ischemic Stroke ll: Pathophysiology
68
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...

Transient Ischemic Attack l: Introduction
34
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...
