Equilibrium and Balance01:15

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic 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...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic 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...
Secondary Spinal Cord Injury llI: Pathophysiology01:25

Secondary 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...
The Vestibular System01:29

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...

Summary
This summary is machine-generated.

Posterior circulation stroke can cause acute vertigo. Early recognition of isolated vertigo or audiovestibular loss is crucial for diagnosing cerebellar or brainstem stroke and preventing further infarction.

Area of Science:

  • Neurology
  • Neuroscience
  • Vascular Neurology

Background:

  • Posterior circulation stroke can manifest as acute vertigo and imbalance.
  • Small cerebellar or brainstem infarcts may present with isolated vertigo, mimicking inner ear disorders.
  • Isolated audiovestibular loss can be an early sign of impending posterior circulation ischemic stroke.

Purpose of the Study:

  • To summarize clinical syndromes and signs of acute vestibular syndrome caused by posterior circulation stroke.
  • To highlight the importance of differentiating stroke-related vertigo from benign conditions.
  • To emphasize the role of early evaluation in preventing stroke progression.

Main Methods:

  • Review of clinical syndromes and signs associated with posterior circulation stroke.
  • Discussion of diagnostic tools like the head impulse test.
  • Analysis of case presentations involving isolated vertigo and audiovestibular loss.

Main Results:

  • Approximately 17% of posterior inferior cerebellar artery territory infarctions present with isolated vertigo, nystagmus, and postural unsteadiness.
  • The head impulse test aids in distinguishing stroke-related vertigo from vestibular neuritis.
  • Acute isolated audiovestibular loss may precede widespread infarction in the posterior circulation.

Conclusions:

  • Acute vestibular syndrome due to posterior circulation stroke requires prompt recognition and evaluation.
  • Early diagnosis and intervention can prevent severe neurological deficits.
  • Understanding these presentations is vital for neurologists and emergency physicians.
