Causes Of Benign Positonal Vertigo

In most people the cause of Benign Positional Vertigo is unknown and there is often no precipitating cause but it can follow viral infections or accidents causing head or neck injuries.

There are 2 theories to explain BPV;

1. There are tiny pieces of floating debris like small crystals in the fluid of the balance centre of the inner ear (the labyrinth), These bits of sediments upset the balance centre when disturbed. This is the most favoured theory.

2. A problem exist in the neck usually a "kink" in some of the swivel joints. The neck is connected to the balance centre by special nervous pathways.
