“…In our study, we have shown for the first time the effectiveness of chronic epidural electrical stimulation of the spinal cord in chronic cerebral ischemia. Given that perfusion changes are observed mainly in the frontoparietal cortex, our results may be potentially useful for developing methods for correcting cognitive impairment in patients with various forms of dementia, as well as for reducing age-related vascular disorders in the elderly (15,27,28). Mechanisms for improving cerebral blood flow during electrical stimulation of the spinal cord have not been sufficiently studied (17,18,21).…”

“…In recent years, various methods of neuromodulation based on epidural electrical stimulation of the spinal cord have been proposed in clinical practice for the correction of peripheral hemodynamic disorders in patients suffering from refractory angina pectoris or peripheral vasculopathy (6)(7)(8)(9)(10)(11). Also, in many experimental and clinical studies, a positive effect of electrical stimulation of the spinal cord on the hemodynamic and functional parameters of the brain was noted in certain pathological conditions associated with dysfunction of the vascular bed, such as ischemia, subarachnoid hemorrhage, head trauma and brain tumors (10,(12)(13)(14)(15)(16). Most of the conducted clinical and experimental studies devoted to the study of the short-term effect of the upper (at the level of C2-C3 of the cervical spinal cord) electrical stimulation of the spinal cord were performed, as a rule, in acute and severe circulatory disorders, accompanied by critical neurological disorders and the development of a vegetative state, such as stroke, vasospasm, or traumatic brain injury (TBI) (17)(18)(19)(20)(21).…”

ObjectiveIncreasing life expectancy and aging of the population is accompanied by a steady increase in the number of elderly patients with chronic cerebral ischemia and age-related cognitive impairment associated with cerebral hypoperfusion and microangiopathy. The aim of this study was to identify long-term changes in cerebral blood flow (CBF) in patients with chronic cerebral ischemia at the epidural electrical stimulation of the spinal cord (SCS).Materials and methodsChanges in cerebral blood flow were studied according to CT perfusion in 59 patients (aged 55–78 years) with vertebrogenic pain syndromes and chronic cerebral ischemia during epidural electrical stimulation of the spinal cord at the cervical (C3–C5) and lower thoracic (Th9–Th10) levels.ResultsIn all patients, on the 5th day of trial SCS, an increase in cerebral blood flow by from 58.6 ± 1.13 ml/100 ml/min to 64.8 ± 1.21 ml/100 ml/min (p < 0.01) with stimulation at the Th9-Th10 level and from 58.8 ± 1.12 ml/100 ml/min to 68.2 ± 1.42 ml/100 ml/min (p < 0, 01) with stimulation at the C3-C5 level. These changes in brain perfusion were preserved during the follow-up examination 1 year after the implantation of chronic SCS system. The greatest increase in CBF was registered in the frontotemporal regions, subcortical structures and white matter of the brain. Changes in cerebral perfusion did not correlate with the degree of reduction in the severity of the accompanying pain syndrome. The change in CBF in the control group (32 patients) in all periods was not statistically significant.ConclusionOur results show that SCS is accompanied by a persistent improvement in brain perfusion, which may be potentially useful for developing methods for reducing age-related vascular disorders in the elderly.
