    Abstract:
    After a detailed review of literature basic and clinical data on rheoencephalography (R.E.G.) the findings of 1000 patients suffering from verified brain blood supply impairment submitted to REG studies are exposed. Following parameters of REG curve have been analysed: sphygmic amplitude, sphygmic interrelations between two homologous brain regions; sphygmic speed, rise time, slope of REG curve, dicrotic incisure, random oscillations of catacrotic phase. A reduction in sphygmic speed has been observed in 70 % of cases, with changes in slope of REG curve in 90 % and reduction or disappearance of catacrotic dicrotism in 93.5 % and progressively less frequent changes in the remaining REG parameters. The obtained data have been submitted to statistical analysis. Significant associations have been observed between two or more pathological REG parameters and between the pathology of REG curve as a whole and the different invasive methods employed for assessing the cerebrovascular insufficiency such as CT, CBF studies and angiographic data. Not significant correlations between the focal REG pathology, and the focal changes of REG or of the invasive methods have been found. The systematic employment of REG study as a non invasive method for the screening of cerebral blood impairment is recommended.
