Equilibrium and Balance

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 System

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 Vomiting

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...

Viral Meningitis

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Hyperpnea and Hyperventilation

Hyperpnea and Hyperventilation

Hyperventilation refers to a higher-than-normal rate and depth of breathing, often associated with anxiety attacks. This excessive breathing surpasses the body's need to expel CO2, leading to a condition known as hypocapnia - an unusually low level of carbon dioxide in the blood. Hypocapnia can constrict cerebral blood vessels, reducing blood flow to the brain, which may result in dizziness or fainting. Early signs include tingling and muscle spasms in the hands and face, caused by falling...

Arboviral Encephalitis

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Summary

Hyperventilation-induced nystagmus (HIN) is common in acute vestibular neuritis (VN) but often resolves. Persistent HIN is linked to ongoing dizziness and poorer outcomes in VN patients.

Area of Science:

Neurology
Vestibular System Disorders

Background:

Vestibular neuritis (VN) is a common cause of vertigo.
Hyperventilation-induced nystagmus (HIN) is a potential indicator of vestibular dysfunction.

Purpose of the Study:

To examine the temporal evolution of HIN in VN patients.
To assess the impact of HIN on dizziness outcomes in VN.

Main Methods:

Quantitative vestibular function tests, including hyperventilation, were performed on 53 VN patients.
The Korean version of the Dizziness Handicap Inventory (DHI-K) was used for dizziness assessment.

Main Results:

HIN incidence decreased from 62% in the acute stage to 17% in the chronic stage.
Persistent HIN was associated with significantly higher rates of dizziness (70% vs 27%) and DHI-K scores.
HIN beating towards the contralesional side showed better dizziness recovery.

Conclusions:

HIN in the acute stage or persistent HIN at follow-up correlates with persistent dizziness in VN.
HIN is a valuable prognostic marker for dizziness outcomes in vestibular neuritis.
