What is benign positional paroxysmal vertigo (BPPV)?
Benign positional paroxysmal vertigo (BPPV) is a disorder of the inner ear. The cause usually is unknown, but an upper respiratory tract infection or a minor blow to the head may be responsible. This type of vertigo occurs abruptly when you move your head up and down, or when you turn over in bed. Symptoms can be distressing but they fade in a few seconds.
Avoiding positions that bring this on may reduce its occurrence.
BPPV is the commonest form of vertigo, with attacks lasting 30 to 60 seconds, typically set off when rolling over in bed, moving the head to one side or reaching for something ("top-shelf vertigo"). Sufferers can usually describe specific head movements that trigger it. Although BPPV often occurs for no apparent reason, it can follow an ear infection, head or ear injury, and is thought to result from the dislodgement of normal crystalline structures in the ear's balance detectors. People with BPPV are often relieved to hear that it is due to an inner ear condition and does not signify some serious disorder such as a stroke or tumor.
Benign positional vertigo may come and go over a period of weeks or years. For this type, healthcare providers may try a canalith repositioning procedure. While lying on the back, the person extends the head over the end of a table. He or she then turns the head to one side, rolls over onto that side, and returns to a sitting position. This is an attempt to move tiny particles around inside the middle ear. Individuals should consult their healthcare provider before using this technique.
