Equilibrium and Balance01:15

Equilibrium and Balance

6.0K
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...

The Vestibular System01:29

The Vestibular System

37.8K
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.

Vascular Spasm01:16

Vascular Spasm

4.6K
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...

Cerebral Edema ll: Pathophysiology

2
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...

Increased Intracranial Pressure ll: Pathophysiology

5
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins...

Increased Intracranial Pressure l: Introduction

6
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component...

Area of Science:

  • Neurology
  • Vascular Neurology
  • Neurotology

Background:

  • Posterior circulation strokes can manifest as vertigo, imbalance, and nystagmus.
  • Small cerebellar or brainstem infarcts may present with isolated vertigo, mimicking peripheral vestibular disorders.
  • Approximately 11% of isolated cerebellar infarcts cause isolated vertigo, nystagmus, and postural unsteadiness.

Purpose of the Study:

  • To review diagnostic keys for acute isolated vertigo syndromes caused by posterior circulation strokes.
  • To highlight the importance of bedside evaluation in differentiating central from peripheral vertigo.

Main Methods:

  • Review of clinical presentations and diagnostic tools for posterior circulation strokes.
  • Emphasis on the head impulse test for differentiating cerebellar strokes from inner ear disorders.
  • Comparison of bedside evaluation efficacy versus MRI for central vascular vertigo.

Main Results:

  • Isolated vertigo can be the sole symptom of cerebellar or brainstem strokes.
  • The head impulse test aids in distinguishing cerebellar strokes from peripheral vestibular disorders.
  • Bedside evaluation is more effective than MRI in identifying central vascular vertigo.

Conclusions:

  • Acute isolated vertigo syndromes due to posterior circulation strokes require prompt recognition.
  • The head impulse test is a valuable tool in the bedside diagnosis of stroke-related vertigo.
  • Clinical evaluation is paramount for diagnosing central vertigo syndromes, often surpassing advanced imaging.
