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...

Increased Intracranial Pressure l: Introduction

Increased Intracranial Pressure l: Introduction

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 expands, CSF and venous blood...

Traumatic Brain Injury l: Introduction

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Increased Intracranial Pressure ll: Pathophysiology

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

Benign paroxysmal positional vertigo (BPPV) affects 9% of concussed adolescents. Higher Dizziness Handicap Inventory (DHI) scores and incomplete Vestibular Ocular Motor Screening (VOMS) predict BPPV risk in this population.

Area of Science:

Sports Medicine
Neurology
Vestibular Disorders

Background:

Concussion is common in adolescent athletes.
Vestibular dysfunction can complicate concussion recovery.
Benign paroxysmal positional vertigo (BPPV) is a potential sequela of head trauma.

Purpose of the Study:

To determine the prevalence of BPPV in acutely concussed adolescents.
To identify risk factors associated with BPPV in this population.

Main Methods:

Retrospective cohort study of 334 adolescents (aged 12-19) with acute concussion.
Assessed symptom severity (Post-Concussion Symptom Scale), vestibular/ocular motor function (VOMS), and BPPV symptoms (Dizziness Handicap Inventory - DHI).
BPPV diagnosis confirmed with standardized testing using infrared video Frenzel goggles.

Main Results:

9% (30/334) of concussed adolescents were diagnosed with BPPV.
BPPV patients had higher DHI scores (median 12 vs. 6) and lower VOMS completion rates (50% vs. 88%).
Incomplete VOMS (OR=4.80) and higher DHI scores (OR=1.17) were significant predictors of BPPV risk.

Conclusions:

Higher Dizziness Handicap Inventory scores and inability to complete the Vestibular Ocular Motor Screening are key risk factors for BPPV in concussed adolescents.
These findings aid in identifying at-risk individuals for timely intervention.
