Vertigo or Dizziness?
Vertigo or dizziness, are symptoms rather than a disease. Vertigo refers to the sensation of spinning or whirling that occurs as a result of a disturbance in your balance (vestibular) system.
Vertigo may be used to describe feelings of dizziness, lightheadedness, faintness, and unsteadiness. The sensation of movement is called subjective vertigo, and the perception of motion in surrounding objects is called objective vertigo.
Vertigo usually occurs as a result of a disorder in the vestibular system (structures of the inner ear, the vestibular nerve, brainstem, and cerebellum).
Your vestibular system is responsible for integrating sensory stimuli and movement and for keeping objects in visual focus as the body moves.
When your head moves, signals transmit to the labyrinth, which is an apparatus in the inner ear made up of three semi-circular canals surrounded by fluid. The labyrinth then transmits movement information to the vestibular nerve and the vestibular nerve carries the information to the brainstem and cerebellum (areas of the brain that control balance, posture, and motor coordination).
The most common cause of dizziness is BPPV. Others include Inflammation in the inner ear, Meniere’s disease, neck joint dysfunction, vestibular migraine and acoustic neuroma. Rarely, vertigo can be a symptom of a more serious neurological problem such as a stroke or brain haemorrhage.
