[Circulatory changes in the neurocirculatory asthenia syndrome].
The results of a comprehensive study of central and cerebral hemodynamics in individuals with the syndrome of neurocirculatory dystonia by means of radionuclide diagnosis are discussed. The shifts revealed provide evidence that hypertonic type of the dystonia syndrome is characterized by increase in the minute cardiac volume, vascular resistance, and minute cardiac output with moderate decrease in the volumetric rate of the cerebral circulation. In hypotonic type of dystonia the volumetric rate of the cerebral circulation is considerably diminished, while central hemodynamics is normal. The study also showed that in the syndrome of neurocirculatory dystonia there was lack of coordination between the systemic and regional cerebral hemodynamics manifested by decrease in the cerebral fraction of the cardiac minute volume.
