Rotatory vertigo can be the result of a central lesion but more commonly it results from a single dysfunction of a very sophisticated and highly specialised neurosensory organ hidden in the temporal bone: the inner ear.
The inner ear plays a crucial role in postural and gaze stability thanks to its semi-circular canals and otolithic organs. It also helps with hearing via cochlear receivers. Any unilateral vestibular or vestibular nerve dysfunction can induce symptoms of severe rotatory vertigo, associated with equilibrium disturbances, and may be accompanied by severe nausea and vomiting.
Life then comes to a standstill and an otoneurological assessment is required to treat the loss of balance and eradicate the underlying cause.
New technologies such as eye tracking, connected objects and virtual reality have favoured the diagnosis and treatment of vertigo. They have revolutionised the field of Otoneurology.
A man can become deaf, blind, dumb, one-armed, legless, a cardiac patient, a TB patient, castrated and yet remain a man. He can fall into a coma and continue to be a passive part of our universe like a rock. But, deprived of his semi-circular canals, he is rejected by the outside the world, whose first law, the condition of constitution, is balance.
He is just a fragment of consciousness of chaos.
