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...
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.
Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through interaction...

Summary
This summary is machine-generated.

Diagnosing acute vertigo is challenging. The head impulse test aids in identifying vestibular neuritis, distinguishing it from stroke or migraine, crucial for effective patient management.

Area of Science:

  • Neurology
  • Otolaryngology

Background:

  • Acute vertigo presents a diagnostic challenge in clinical practice.
  • Key differential diagnoses include vestibular neuritis, cerebellar stroke, and migraine.

Purpose of the Study:

  • To outline diagnostic approaches for acute vertigo.
  • To differentiate common causes of acute vertigo.

Main Methods:

  • Clinical history taking.
  • Focused neurological examination.
  • Specific diagnostic tests such as the head impulse test.

Main Results:

  • The head impulse test is positive in vestibular neuritis, aiding differentiation.
  • Acute vertigo with hearing loss may suggest Ménière's disease, but anterior inferior cerebellar artery stroke must be considered.
  • Brainstem signs help distinguish stroke from other vertigo causes.

Conclusions:

  • A careful history and focused examination are essential for evaluating acute vertigo.
  • The head impulse test is a valuable tool in the acute assessment of vertigo.
  • Distinguishing between vestibular neuritis, stroke, and other vertigo etiologies is critical for appropriate management.
