Which are the symptoms?
The main symptom is the onset of significant rotational vertigo associated with nausea and/or vomiting, lasting about 2-3 days. The vertigo crisis is not accompanied by changes in hearing. At the end of the acute phase, which usually lasts a few days, a temporary feeling of unsteadiness may persist for a variable period of several weeks, the time needed for compensation for insufficient vestibular function.
· Prolonged rotational vertigo (several days)
· Nausea and/or vomiting
How is it diagnosed?
Diagnosis is based on a correct anamnestic history and a complete clinical otvestibular instrumental examination, which today includes the Video-Head pulse test in level II-III outpatient clinics and observation of spontaneous positional nystagmus with Video-Frenzel. In addition, imaging of the central nervous system is indicated for the differential diagnosis of problems of vascular origin.
How is it treated?
Treatment includes symptomatic drugs for nausea and/or vomiting, steroids to reduce nerve inflammation and restore vestibular function, and vestibulodepressants (only for a short time). After the acute phase has passed, vestibular rehabilitation is indicated for those who have not been able to achieve a good balance recovery with medical therapy alone.
