Clinical and Rheoencephalographic Possibilities in Differential Diagnostics of Cerebral Vascular and Tumor Diseases

Vascular nervous system lesions are now the most important of all problems of clinical neurology.This is primarily due to the high prevalence of cerebro-vascular diseases [1][2][3].In economically developed countries, mortality rate due to these diseases accounts for about 12% of all population mortality, second only to mortality due to heart disease and tumors of all localizations.American statisticians write that the damage caused to the state by cerebral stroke is estimated at more than 1 billion dollars a year [4][5][6][7].Thus, the problem of prevention and treatment of cerebral vascular lesions has become a serious not only medical but also socio-economic problem.As a result of preventive and therapeutic measures, a tendency to reduce mortality rate due to cerebral vascular lesions is already beginning to emerge and new encouraging prospects are opening up.Therefore, every year more and more attention of clinicians and physiologists dealing with cerebral blood circulation in norm and pathology is attracted to a very important non-invasive method of recording the state of cerebral vessels and changes in cerebral circulatory dynamics -"rheoencephalography".
