DIAGNOSIS AND TREATMENT OF VERTIGO
It is a very common disorder that causes a characteristic nystagmus depending on the duct that presents the accumulation of otoconia and that produces an episodic vestibular syndrome of short duration, usually less than a minute. It usually occurs when lying down, when the patient turns in bed, or when lowering the head. The subject perceives a rotation of objects with changes in position, although the elderly describe instability. All of this can be accompanied by nausea or vomiting.
The diagnosis is based on the detection of the characteristic symptoms described and on exploratory tests. These include the Dix-Hallpike test and the head rotation or McClure test. With them you can determine the affected channel and the presence of the problem in one or two ears.
