Query: Electrostimulation of Brain Deep Structures in Parkinson's Disease   The study involved 56 patients with advanced and late stages of Parkinsons
disease, which could be considered as potentially requiring neurosurgical
treatment-electrical stimulation of deep brain structures. An algorithm has
been developed for selecting patients with advanced and late stages of
Parkinsons disease for neurological treatment-implantation of a system for
electrical stimulation of deep brain structures in distant neurosurgical
centers, which includes two stages for patients with limited mobility -
outpatient and inpatient. The development of an algorithm for referral to
neurological treatment has shortened the path of a patient with limited
mobility from a polyclinic to a neurological center. Electro stimulation of
deep brain structures in Parkinsons disease significantly improved the
condition of patients-to increase functional activity by 55%, reduce the
severity of motor disorders by 55%, and reduce the dose of levodopa drugs by
half.
