[Neurosurgical therapies for movement disorders in 2025].

For several decades, deep brain stimulation has been a major breakthrough in the treatment of movement disorders, significantly improving the quality of life of patients with Parkinson's disease, but also with dystonia or tremor. Thanks to technological advances, this therapy continues to evolve: directional electrodes, adaptive stimulation, and neural recordings allow for more precise targeting and better clinical outcomes. At the same time, epidural electrical stimulation opens up new perspectives, notably for gait disorders, and represents a promising step forward in the field of therapeutic neuromodulation.
