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...

Major Somatic Sensory Pathways

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...

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.

Hemorrhagic Stroke ll: Pathophysiology

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Hemorrhagic Stroke l: Introduction

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Cerebellum: Anatomical Regions

Cerebellum: Anatomical Regions

The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...

Summary

Vertigo can indicate a higher stroke risk, especially when isolated. Prompt diagnosis of brainstem or cerebellar strokes is crucial to prevent severe outcomes and unnecessary treatments.

Area of Science:

Neurology
Otolaryngology

Background:

Vertigo is a common symptom with diverse causes.
Patients experiencing isolated vertigo may have an increased risk of stroke.

Purpose of the Study:

To review recent findings on the prevalence, clinical features, and diagnosis of vertigo associated with brainstem and cerebellar strokes.
To highlight the importance of accurate diagnosis in managing vascular vertigo.

Main Methods:

Literature review of recent studies on vertigo and stroke.
Analysis of clinical features and diagnostic methods for central vestibular syndromes.
Evaluation of diagnostic tools such as bedside examination and vestibular-evoked myogenic potentials (VEMPs).

Main Results:

Strokes in the brainstem and cerebellum can present as acute vestibular syndrome.
Acute isolated audiovestibular loss may signal an anterior inferior cerebellar artery infarction.
Bedside evaluation is more effective than MRI for detecting central vestibular syndromes.
VEMPs aid in assessing central otolithic pathways in posterior circulation strokes.

Conclusions:

Accurate identification of vascular vertigo is critical to avoid misdiagnosis, which can lead to significant morbidity and mortality.
Overdiagnosis of vascular vertigo can result in unnecessary investigations and treatments.
