POSITIONAL VERTIGO Meaning and
Definition
-
Positional vertigo, also referred to as benign paroxysmal positional vertigo (BPPV), is a vestibular disorder characterized by a sudden and intense spinning sensation that occurs with certain head movements or changes in position. It is the most common form of vertigo and typically results from displaced calcium carbonate crystals, known as otoliths or canaliths, within the inner ear.
The inner ear contains specialized structures responsible for maintaining balance and spatial orientation. When otoliths become dislodged from their normal position and migrate into the semicircular canals, which are responsible for detecting rotational movements, they can disrupt the normal flow of fluid within the canals. As a result, when head movements are made, such as rolling over in bed, tilting the head back, or looking up, the displaced otoliths cause a confusion in the brain's perception of body position, generating a brief but intense episode of vertigo.
Common symptoms of positional vertigo include dizziness, a spinning or whirling sensation, nausea, and occasionally, imbalance. These symptoms are typically triggered by specific head movements and can last from a few seconds to a couple of minutes. It is important to note that positional vertigo does not cause hearing loss or have any associated neurological symptoms.
Treatment for positional vertigo is primarily based on repositioning exercises, also known as canalith repositioning procedures, that aim to relocate the displaced otoliths to their normal position within the inner ear. These exercises involve specific head and body movements under professional supervision or as instructed by a healthcare provider. In some cases, medication may be prescribed to alleviate symptoms or control underlying conditions contributing to vertigo.

Etymology of POSITIONAL VERTIGO
The word "positional vertigo" is a combination of two terms: "position" and "vertigo".
1. Position: The word "position" comes from the Latin word "positio", which means "a placing, a position, a situation, or a condition". It is derived from the verb "ponere", meaning "to put or place". In English, "position" refers to the placement or posture of something or someone, or a particular state or situation.
2. Vertigo: The term "vertigo" originates from the Latin word "vertere", which means "to turn or spin". It is also related to the Latin word "verto", which means "I turn". "Vertigo" refers to a sensation of spinning, dizziness, or loss of balance. It is commonly associated with disorders of the inner ear or disturbances in the vestibular system.
