What are the defining features of BPPV (Benign Paroxysmal Positional Vertigo)?

Benign Paroxysmal Positional Vertigo (BPPV) is a common cause of dizziness. It happens when you move your head in certain positions, like tilting your head back or turning over in bed, and it makes you feel like the room is spinning. This feeling usually lasts for a short time, often less than a minute.

Key Features of BPPV:

• Sudden Dizziness: The dizziness starts suddenly and is usually triggered by specific head movements.
• Brief Episodes: Each dizzy spell is short, typically lasting less than a minute.
• Positional Trigger: The dizziness occurs with changes in head position, such as looking up, bending down, or getting out of bed.

BPPV is caused by tiny calcium particles that are in the inner ear, which help with balance. These particles can become dislodged and move into areas where they shouldn't be, causing the dizziness. Although BPPV can be bothersome, it is not dangerous and can often be treated effectively with specific head exercises that help move the particles back to where they belong.
