AGE-RELATED DECLINE INTENSITY BLOOD SUPPLY LIMBS AND THE HUMAN BRAIN
Aim. Determination of the causes of age-related decrease of blood flow velocity (BFV) in the middle cerebral artery (MCA). Methods. BFV on MCA was identified by the transcranial dopplerography. It was carried out the analysis of the indicator change in functional muscle probein 941 healthy people 5-75 years old and 30 patients 3-62 years old witha growth lag of one of the lower limbs in the course of its operational extension. As the indicator of cerebral blood flow autoregulation was used changes excursion of BFV indicators in the repetitive muscle functional probe. Results. It has been found that there is an age reduction ofblood flow velocityin the middle cerebral artery, more pronounced in patients with musculoskeletal system disorders. At the same time, the average value of the excursion of blood flow velocity index changes in the functional probe in healthy individuals from 10 y.o., as well as in patients before treatment and during the fixation keeps stable. Conclusion. Age-related decrease in the BFV at MCA is a prerequisite for the preservation of cerebral autoregulation. In a cerebral autoregulation disturbance the efficiency of patients with limbs distraction is greatly degraded.
