Vertigo and migraine
The vascular system and its influence under sympathetic and parasympathetic stimulations plays an essential role in neurophysiology of equilibrium.

The evaluation of vertebral artery involvement in vertigo by means of a standard echodoppler procedure
The vertebral artery origins from the subclavian artery, moves cranially and penetrates into the “foramen magnum” to meet the cotralateral artery so to origin the basilary artery. The length of the vertebral artery is approx. 25 cm. with a diameter between 3 and 6 mm. In 60% of the normal population, the vertebral arteries don’t […]
Vestibular evoked myogenich potentials in monitoring the efficacy of vestibular rehab in water
Water represents a simple way to modify gravity interaction on human body. In this way it is possible to manipulate the vestibular system. Vestibular Rehabilitation in Water is the new perspective of rehabilitation of Vertigo and Equilibrium Disturbances. One of the most important role of the CS is to detect Gravity and to elaborate adequate […]
The role of free radicals and plasmatic antioxidant in menière syndrome
The objective of this study is the supposition, verified through suitable hematochemical tests, of the co-presence in the etiopathogenesis of the Menière syndrome and/or in the labyrinth pathologies or hypacusia also of central/systemic microtoxicosis. We do not therefore exclude other well known hypotheses on the causality of these pathologies, but one finds, above all in […]
Vestibular evoked potentials (vbep): methodological and systematical aspects
The vestibular pathway, like other sensorial systems, has a cortical representation. In 1985 we have published our first investigation on «Variations of the cortical electrical activity during supramaximal vestibular stimulations».
News technics diagnosis in vertigo patients
The diagnosis of patients in modern neuro-otogical centres has to include not only history and examination, but also objetive and quantitative tests. In this study stress the importance of a short but significant Many authors had reported different usefull studies in the evaluation of the nystagmus which may be spontaneous and induce, any one of […]
The role of subcortical motor neurons in balance disorders- experimental study of the plasticity of the system
Several data indicate that compensation and habituation processes are the main phenomenons of the plasticity of central nervous system (CNS), especially the plasticity of vestibular system. The detailed role of particular parts of CNS in adapatation after lessions has not been clear yet (2). Evertbody knows that in birds and reptiles cerebral motor cortex in […]
Bppv and vasopressine
The possible relationship between inner ear and vasopressin (AVP, ADH) has been hypothesized since twenty years ago About ten years ago, in anaesthetized guinea pigs, we demonstrated that changes in the inner ear pressure modify plasma AVP (pAVP) level and AVP secretion with consequent changes in urine flow rate and osmolality : our experiment was […]
Freyss’ stabilometry and posturography- a comparison study
The usefulness of conventional posturography when the changes of muscle tonus of the lower limbs affect position of the center of gravity which movement is measured is well known. The radius of the gravity center deflection such as length of the „way” and velocity of the movement can be calculated and compared during sequences with […]
Navigation test
The balance system allows to our body to have a right relation with environment, this is probably due by different structures that collaborate to maintain the correct voluntary posture during erect position and the clear vision of the ambience; with regard to its synergetic purpose the balance system can therefore be schematised on the base […]
