简要总结

Phase 1 study evaluating the safety of combined bilateral globus pallidus internus (GPi) and nucleus basalis of Meynert (NBM) stimulation in treating levodopa responsive motor symptoms of Parkinsonism and cognitive dysfunction, respectively, in patients with moderate to advanced Parkinson's disease having mild cognitive impairment.

详细描述

This study aims to provide a proof of safety of combined bilateral Globus Pallidus internus (GPi) and Nucleus Basalis of Meynert (NBM) stimulation in patients with moderate to advanced Parkinson's disease having mild cognitive impairment.

GPi stimulation with high-frequency ameliorates the cardinal motor symptoms and motor complications in Parkinson's disease patients, and this present study also wants to determine if additional NBM stimulation, with low-frequency stimulation, improves or slows progression of cognitive decline in patients with moderate to advanced Parkinson's disease having mild cognitive impairment, and to evaluate the effect of NBM stimulation on gait and balance impairment.

Study Design: Prospective single center Phase 1 study with double-blind randomized delayed activation of basal nucleus of Meynert neurostimulation (staggered onset design).

Planned Number of Subjects: 10 patients.

Planned Number of Sites / Countries: Single center in Brazil.
