The following measures can be used to prevent the development of BPPV. The prognosis depends on the severity of concomitant pathology. The disease can become dangerous when the patient is at a significant altitude or depth with associated changes in atmospheric pressure, as well as in the event of a seizure developing in the operator of the mechanisms.

Dizziness is a common complaint that forces a person to see a doctor. This condition accompanies neurological diseases, spinal damage, blood diseases and blood loss, cardiovascular system, poisoning and intoxication. Benign paroxysmal positional vertigo (BPPV) is associated with pathology of the inner ear, which serves as a balance organ in humans. This type of dizziness develops in strictly defined situations, has its own distinctive characteristics and requires a specific approach to diagnosis and treatment.

  • To help me write my research paper the reasons for the development of benign positional vertigo, you need to understand the structure of the inner ear, which is located in the temporal bone and helps a person hear sounds and maintain balance when moving in space.
  • This is the first part of the inner ear, which, through the oval window, is in contact with the middle ear, the tympanic cavity that receives sounds from the external auditory canal. Inside the bony walls of the vestibule there is a fluid-filled membranous labyrinth. In its vestibule there is an elliptical and spherical sac, which is responsible for the perception of static vibrations of the head and its movement in a straight line.
  • This is a spirally twisted bone formation, inside of pay for term paper there is also a membranous labyrinth filled with fluid. It houses the organ of Corti, a formation that makes it possible to transform sound waves into nerve impulses that can be deciphered in the brain. Bone semicircular canals.
  • These are curved bone tubes located in three mutually perpendicular planes. Inside them there is another part of the membranous labyrinth, containing extensions - membranous ampoules. Receptors in the ampoules are responsible for the perception of body movement and head rotation in various directions and planes.

  • Benign paroxysmal positional vertigo occurs when individual parts of the elliptical sac (fragments of the otolithic membrane) separate and move into the membranous labyrinth of the semicircular canals. Considering the location of the canals in space, most often these formations fall into the posterior (vertical) semicircular canal. Independently leave the lumen of the semicircular canalsinto fragments of the otolithic membrane cannot due to anatomical features.
  • Parts of the otolith membrane move through the fluid of the membranous labyrinth and imitate human movement in space. Due to the discrepancy between the picture before the eyes and the effect on the receptors of the vestibular apparatus, dizziness occurs.

In this case, other causes may be present in parallel - infectious diseases, neurological pathology and organic brain damage. Benign paroxysmal positional vertigo, or postural vertigo, most often develops in people over 50 years of writing essays for money. At this age, the incidence of BPPV is up to 40% and increases thereafter. The disease affects women 2 times more often than men. There are no differences by ethnicity or race.

With benign positional vertigo, the most disturbing symptom for a person is the loss of balance itself, which has the characteristic features listed below. The development of dizziness is accompanied by a number of symptoms that also cause significant discomfort and require additional treatment (described below). A swaying sensation accompanied by unsteadiness and unsteadiness when walking. Nausea and, in severe cases, vomiting. Increased sweating regardless of ambient temperature.

BPPV is considered a benign type of dizziness. This is due to the short duration of attacks, the small number of accompanying symptoms and the favorable course of the disease. However, any type of dizziness requires a detailed examination in a medical institution, since this symptom is a manifestation of serious and sometimes life-threatening diseases. Moreover, BPPV also poses a danger to a person's life, for example, when an attack of dizziness develops. Against the background of BPPV, mental disorders and phobic conditions can also appear, in which the anticipation of an attack causing uncontrollable fear, up to and including a panic attack. In these situations, it is important to distinguish cause and effect, that is, the underlying disease from the complication.

To confirm or refute the diagnosis of BPPV, the Dix-Hallpike test, developed in 1952, is performed. The essence of essay test is to provoke the development of BPPV symptoms by the actions of a doctor. Confirmation or refutation of the diagnosis depends on whether dizziness can be caused by such maneuvers.

To treat BPPV and associated symptoms effectively and avoid relapses, the cause of this condition must be determined. Typical causes of the development of benign paroxysmal positional vertigo include: Also, before starting treatment, you should check whether the complaints attributed to BPPV are associated with orthostatic hypotension. In this case, the level of blood pressure changes when moving from a horizontal to a vertical position. Due to this, similar symptoms arise - dizziness and nausea. The main sign that allows you to distinguish orthostatic hypotension from BPPV is a change in blood pressure levels when you change body position.
