Summary
Transient ischemic attack (TIA) incidence in Brazil is lower than previously reported, with 15 cases per 100,000 people. Further research is needed to determine if this reflects true incidence or underascertainment.
Area of Science:
- Neurology
- Epidemiology
- Public Health
Background:
- Limited data exists on transient ischemic attack (TIA) incidence in low- and middle-income countries.
- Understanding TIA rates is crucial for public health planning and resource allocation.
Purpose of the Study:
- To determine the incidence of transient ischemic attack (TIA) in Joinville, Brazil.
- To analyze the distribution of the ABCD2 risk score among TIA patients in the study population.
Main Methods:
- A comprehensive ascertainment of first-ever probable and definite TIAs was conducted between 2009 and 2010.
- Multiple overlapping data sources were utilized to ensure thorough case identification.
Main Results:
- A total of 74 definite and probable TIAs were recorded.
- The crude incidence rate was 15 (12–18) per 100,000 population, with an age-adjusted rate of 28 (22–35) per 100,000.
- Approximately 25% of patients scored as high risk for stroke using the ABCD2 scale.
Conclusions:
- The incidence of TIA in Joinville, Brazil, appears lower compared to findings from other well-designed international studies.
- Further investigation is warranted to ascertain whether these observed rates are due to underascertainment or represent a genuinely lower incidence in this population.

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...
01:08Prevalence and Incidence
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.

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.
01:17Hemorrhagic 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...
01:15Ischemic 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...
01:29Hemorrhagic 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...
