The dizziness is an impression(printing) of rotation of the body in the space or the space with regard to(compared with) the body.For the balance: three sensory systems (vestibulaire, proprioceptif, picture), with numerous interconnections. Integration of the information by a central system (brainstem, cerebellum, cortex(cortices).
For vertigo: inadequacy of information between the three sensory systems.
The consequences are driving (hypotonia), oculomotor (nystagmus) and vegetative (vagal). Here one can speak of a central compensation: progressive learning dysfunction through Fourmies information by the vision and proprioception.
It should also eliminate imbalances (central origin), unstable ground printing, seasick, drunk no real rotary printing. The clinical examination including otologic examination +++ otoscope acoumetry sign fistula (vertigo when the pressure on the tragus).
The study of nystagmus; involuntary rhythmic oscillations of the eyes in two shakes: slow (vestibular origin), fast (booster) that defines the side of nystagmus.
For neurological examination, there is a maneuver Romberg postural balance, the deviation of the index and the blind walk. For additional tests, there are two key tests: audiometry screening for hearing loss. The second consideration is the vestibular testing with nystagmography: energizing a semi-circulairepar caloric or rotational stimulation channel and then recording by videonystagmography nystagmus.
Is made further examinations based on the suspected etiology.
For treatment, the patient should be reassured sue character Benin dizzy, do a liberating maneuver Fremont (Hallpike maneuver for 4 minutes, then more abruptly put the patient in the lateral decubitus position on the opposite side for 4 minutes), prevent the risk side opposite the side to prevent the risk of recurrence.
