Positional vertigo (benign paroxysmal positional vertigo) is a condition that affects how the inner ear communicates information about position to the brain. It is the most common reason for the feeling of dizziness known as vertigo, according to Medline Plus.
Symptoms
Positional vertigo creates a sudden feeling of spinning when the head moves; according to Medline Plus, more severe symptoms include perceiving that things seen are in motion, as well as vomiting.
Cause
Positional vertigo happens when an otolith organ in the semicircular canal of the inner ear breaks free; this organ, according to the Mayo Clinic, normally helps the brain use information about the body's position.
Features
The otolith organ might be impacted by a head injury, illness or surgery performed on the area, according to the Mayo Clinic.
Time Frame
This condition occurs mostly in people who are over the age of 60, according to the Mayo Clinic, and may sometimes run in families, according to Medline Plus.
Treatment
Treatment for positional vertigo includes removing the affected otolith organ or using antihistamines, anticholinergics or sedative-hypnotics to treat the sensation of spinning, although Medline Plus reports that these medications often do not relieve symptoms well.
