[The dynamics of the cerebral circulation under the influence of laser therapy in patients with circulatory encephalopathy].

The cerebral circulation was rheoencephalographically studied in 23 patients before the first session and after a course of pulse laser exposures at 80 Hz and at a wavelength of 0.89 microns. There was a positive dynamics in 42.9 and 56.1% of cases, as evidenced by rheoencephalography of the vertebral and internal carotid artery beds, respectively. Negative vascular responses were likely to occur as impaired intracranial venous circulation. Rheoencephalographic changes were found to be associated with the Doppler ultrasound findings of the capital great vessels and with neurological data.
