What is BPPV?
BPPV stands for benign paroxysmal positional vertigo, and it is short, intense and recurrent attacks of vertigo, often accompanied by nausea without vomiting. It can occur during certain head movements. It is caused by small fragments of debris (crystals) that get loose and start floating in the fluid of the inner ear. The fragments are no trouble when the head is still, but when the head is moving, they are swept along the fluid-filled canal, sending confusing messages to your brain. As a result, a vertigo attack occurs.
About 1 in 50 people will suffer from BPPV. The condition can develop for no apparent reason, or as a result of an ear infection, ear surgery, a head injury, or prolonged bed rest (most commonly when recovering from an illness). If there is a family history of BPPV, the risk increases. [3, 5]
What is Vestibular Neuronitis?
Vestibular neuronitis (also referred to as vestibular neuritis) is an inner ear problem that causes inflammation of the nerve connecting the labyrinth to the brain. Sometimes the labyrinth itself is affected. The condition is normally caused by a virus. It usually comes on suddenly and lasts for a few hours or days, but sometimes it can take several weeks to settle completely. Other symptoms that may develop are unsteadiness, nausea and vomiting, but no hearing loss. [3]
What is Meniere’s Disease?
Meniere’s disease is a condition that combines symptoms of severe dizziness with occasional hearing loss. It is possible to experience sudden attacks of vertigo that may remain for hours or even days, accompanied by nausea and vomiting. The cause of the disease is unknown, but it can be triggered or aggravated by stress, salty food, coffee and alcohol. Dietary changes and medication are usually enough to control the condition, although sometimes surgery might be required. [3, 4]
