Equilibrium and Balance01:15

Equilibrium and Balance

6.1K
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

43.1K
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.

Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

2.2K
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...

Perceptual Constancy01:12

Perceptual Constancy

1.1K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

1.7K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Mitral Valve Prolapse II: Assessment and Management

310
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Area of Science:

  • Neuroscience
  • Otolaryngology
  • Psychiatry

Background:

  • Persistent postural-perceptual dizziness (PPPD) is a chronic vestibular disorder characterized by fluctuating symptoms.
  • Symptoms include dizziness, unsteadiness, or non-vertiginous vertigo lasting over three months.
  • Triggers encompass vestibular events, balance disruptions, medical conditions, and psychological distress.

Purpose of the Study:

  • To define Persistent Postural-Perceptual Dizziness (PPPD) within the International Classification of Vestibular Disorders.
  • To outline diagnostic criteria and differentiate PPPD from other conditions.
  • To highlight ongoing research into pathophysiology and treatment.

Main Methods:

  • Diagnosis relies on identifying key historical symptoms.
  • Physical examinations and diagnostic testing are crucial.
  • Exclusion of other potential illnesses is part of the diagnostic process.

Main Results:

  • PPPD is defined by symptoms exacerbated by upright posture, motion, and complex visual environments.
  • A wide range of conditions can trigger PPPD.
  • Research is yielding insights into underlying pathophysiological mechanisms.

Conclusions:

  • PPPD is a distinct chronic vestibular disorder with specific diagnostic criteria.
  • Multimodality treatment plans are supported by ongoing research.
  • Effective treatments include vestibular rehabilitation, medication, and cognitive-behavior therapy.
