The tinnitus can be functionally measured and localized through sensorymotor and neurosensorial tests. According to our Data Bank, 60% of the patients requiring a consultation show cardiocirculatory background. This figure has moved us to study cerebral vascular processes on those patients consulting only on tinnitus symptom.
During the last half century, medical developments have expedited an increase of expectation of life, all over the world. This extension of life has made that some pathologies that in former years were considered of low prevalence, nowadays they have become top priority for public health.
Tinnitus can be functionally measured and localized through sensorimotor and neurosensory tests. According to our Neurofisiología Otooftalmológica data bank, 60% of patients requiring a consultation have a history of cardiocirculatory disorders. This figure has moved us to study cerebrovascular processes in those patients seeking consultation for a tinnitus symptom only. The sudden appearance of the [...]
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 [...]
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 [...]
Según nuestra experiencia el sistema vascular y su influencia bajo estímulos simpáticos y parasimpáticos juega un rol fundamental en la neurofisiología del equilibrio. Toda modificación del calibre arterial ya sea a nivel periférico o central bajo la dependencia del sistema simpático puede originar trastornos de nutrición a nivel de las células con modificación de sus [...]
The left ventricle is a pump which applies pressure to the circuit on an intermittent way (with each systolic ejection) and sets a pattern of pulsatile flow.
