Abstract
The vascular system and its influence under sympathetic and parasympathetic stimulations plays an essential role in neurophysiology of equilibrium.
Every modification of arterial calibre, wherever it may be located at peripherical or central level, depending on sympathetic system may produce nutritional troubles at celular level with alterations in their functions. These changes can be due to vasodilating phenomena as it is the case of hypotension or to arteriole spasms , as it is the case of hypertension.
At our «Otoophtalmological Neurophysiology» Data Bank with 7800 patients 78% consult on vertigo or dizziness joined to neurovegetative symptoms and tinnitus. In this group, 54% show migraine or headache background. And only 22% consult on migraine.
The patients have been under investigation by means of:
- Equilibriometrical Examination
- Cerebral Haemodynamic Examination
- Brain Electrical Activity Mapping
The neuronal biochemical changes which go together with the cerebral deterioration result in variations of the electrical activity of the neuron. These neuronal bioelectric changes or changes in «tonus», could be early measured by non invading and bloodless methods.
These methods allow the investigation of transitory functional events, as cerebral sensorial activation and the cerebral circulation.
According to results obtained in neurootological functional examinations, treatment should be applied in four directions, improving:
- cerebral circulation
- active transportation of substances through hematoencephalic barrier
- neuronal metabolism
- activity of the main neurotransmitters
