Dr. BPPV has some distinctive symptoms that allow a correct diagnosis to be made during the first examination by a doctor. The structure of the vestibular apparatus. Paroxysmal benign positional vertigo occurs due to the precipitation of calcium salts (otoliths) in this capsule. Further, they contribute to irritation of receptors, due to which a pathological condition appears. It is not always possible to determine exactly what exactly caused such dizziness. However, there are some known causes that contribute to the symptoms.
The symptoms have the following characteristics.
Trauma to the skull, in which the otoliths are torn away from their permanent location. Inflammation of the vestibular apparatus due to a viral infection entering the body. Meniere's pathology. Surgery on the inner ear. Alcohol intoxication. Treatment with certain types of medications. Spasm of the labyrinthine artery, as a result of which normal blood circulation of the vestibular apparatus is disrupted. Migraine. Paroxysmal positional vertigo affects almost everyone in the same way.
A person experiences sudden attacks that appear during certain movements or in a specific body position. with a bowed head and a bent neck. Often, positional vertigo does not last more than half a minute. A person with such a lesion is able to independently identify the diseased ear, since it is from this side that the attack will be noted. During paroxysmal positional vertigo, nausea often occurs.
Basically, the pathological condition is single, although periodic attacks (up to several times a day) are not excluded.
If the patient does not perform actions that provoke dizziness, then it will not appear. The attacks always proceed the same way, the clinical picture never changes. Most often, benign dizziness develops in the morning and before lunch. This pathology does not cause other neurological problems. The attack can occur suddenly.
How is the disease diagnosed? Benign paroxysmal positional vertigo is diagnosed quickly and easily. The doctor just needs to listen carefully to the patientвЂ�s complaints and ask a few questions. However, in order for the diagnosis to be made as accurately as possible, the doctor can perform a special Dix-Hallpike test.
It's not difficult to do. To do this, the patient is asked to sit on the couch, and the doctor turns his head to the left or right 45 degrees. This way the head is fixed, and the patient quickly lies on his back. The rotation angle must not be violated. And your head should be tilted back a little, that is, slightly hanging off the couch. Next, the doctor should observe eye movements and ask the patient about his sensations.
If the test is positive, the doctor can make a diagnosis. In order to notice nystagmus (eye movement), a specialist will need special glasses. Infrared motion detection is also used. For a detailed story about the diagnosis, watch the video from Candidate of Medical Sciences, Associate Professor of the Department of Otolaryngology, Russian National Research Medical University named after. N.I. Pirogova Alexandra Leonidovna Guseva.
So, the form of BPPV (benign paroxysmal positional vertigo) depends on the location of the calcium bicarbonate salt particles.
The patient should also exclude stroke, symptoms of multiple sclerosis, and vertebrobasilar circulatory failure. They are characterized by additional symptoms that do not appear with paroxysmal positional vertigo.
