Benign paroxysmal positional vertigo (BPPV) 良性陣發性姿勢性眩暈 耳石症
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo — the sudden sensation that you're spinning or that the inside of your head is spinning.
Benign paroxysmal positional vertigo causes brief episodes of mild to intense dizziness. Benign paroxysmal positional vertigo is usually triggered by specific changes in the position of your head. This might occur when you tip your head up or down, when you lie down, or when you turn over or sit up in bed.
The signs and symptoms of benign paroxysmal positional vertigo (BPPV) may include:
- Dizziness
- A sense that you or your surroundings are spinning or moving (vertigo)
- A loss of balance or unsteadiness
- Nausea
- Vomiting The signs and symptoms of BPPV can come and go, with symptoms commonly lasting less than one minute.
Episodes of vertigo can last a few seconds, a few minutes, a few hours, or even a few days. In general, however, an episode of vertigo typically lasts just seconds to minutes.
Vertigo isn’t a disease or condition. Instead, it’s a symptom of a condition. Identifying the underlying cause of your vertigo can help you and your doctor find a treatment that works to prevent the episodes.
