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...
Anatomy of the Ear01:16

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
Auditory Perception01:17

Auditory Perception

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

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 with...

Summary

Migraine is strongly linked to hearing and balance issues. Auditory-vestibular dysfunction-associated migraine is a common cause of episodic vertigo, presenting diagnostic challenges.

Area of Science:

  • Neuroscience
  • Otolaryngology
  • Neurology

Background:

  • The connection between hearing/balance disorders and migraine dates back to ancient Greece.
  • Migraine neurotological manifestations are reviewed, focusing on recent publications.

Purpose of the Study:

  • To define "Migraine associated with auditory-vestibular dysfunction" for improved diagnosis and management.
  • To aid otorhinolaryngologists and neurologists in recognizing this clinical entity.

Main Methods:

  • Comprehensive literature review of recent publications.
  • Analysis of epidemiology, clinical presentation, pathophysiology, diagnostics, and treatment.

Main Results:

  • Auditory-vestibular dysfunction-associated migraine is a leading cause of spontaneous episodic vertigo.

  • Symptoms vary widely, complicating diagnosis for specialists.
  • Vertigo spells, with or without positional triggers, accompany migraine symptoms.
  • Conclusions:

    • Understanding the link between vestibular and migraine mechanisms is crucial.
    • Ionic channel disorders may play a role in migraine, ataxia, and vertigo.
    • Further research can elucidate the pathophysiology of auditory-vestibular dysfunction in migraine.
