Summary
Idiopathic sudden sensorineural hearing loss (ISSHL) does not increase stroke risk. Patients who experienced stroke after ISSHL had pre-existing stroke risk factors, highlighting the importance of managing these factors.
Area of Science:
- Neurology
- Otolaryngology
- Epidemiology
Background:
- The relationship between idiopathic sudden sensorineural hearing loss (ISSHL) and the risk of subsequent stroke remains incompletely understood.
- Investigating this association is crucial for understanding potential shared risk factors and informing clinical management.
Purpose of the Study:
- To determine the incidence of stroke following idiopathic sudden sensorineural hearing loss (ISSHL).
- To compare the characteristics of patients who developed stroke versus those who did not after ISSHL.
Main Methods:
- A retrospective cohort study was conducted involving 349 patients diagnosed with ISSHL between 2000 and 2004.
- Patients were followed up until 2009, with stroke incidence analyzed using Cox proportional hazards regression, adjusting for key demographic and medical factors.
Main Results:
- The average annual stroke incidence rate was 0.6%, comparable to the general population.
- Patients who experienced stroke were more likely to be older and have a history of hypertension, coronary artery disease, and prior stroke.
- Prior stroke history emerged as the most significant risk factor for stroke in this cohort.
Conclusions:
- Idiopathic sudden sensorineural hearing loss (ISSHL) itself does not appear to elevate stroke risk.
- The occurrence of stroke in patients with ISSHL is primarily attributed to the presence of established stroke risk factors.
- Clinical focus should prioritize the prevention and management of modifiable stroke risk factors in patients with ISSHL.

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...
01:15Ischemic 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...
01:29Stroke: 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...
01:17Hemorrhagic 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...
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
