Parkinson's Disease.

Med Clin North Am 2019 Mar 3;103(2):337-350. Epub 2018 Dec 3.

Department of Neurology, University of Maryland School of Medicine, 110 South Paca Street, 3rd Floor, Baltimore, MD 21201, USA.

The diagnosis of Parkinson disease (PD) is based on the presence of bradykinesia and either resting tremor or rigidity and there should be no features from the history or examination to suggest an alternative cause of parkinsonism. In addition to the motor manifestations of PD, there is a long list of nonmotor symptoms, several of which occur before motor signs and are considered "prodromal" PD. These are classified as neuropsychiatric, autonomic, sleep, and sensory. Read More

The Pioneering and Unknown Stereotactic Approach of Roeder and Orthner from Göttingen. Part II: Long-Term Outcome and Postmortem Analysis of Bilateral Pallidotomy in the Pre-Levodopa Era.

Stereotact Funct Neurosurg 2018 16;96(6):353-363. Epub 2019 Jan 16.

Department of Neurology, Inselspital, University Hospital Bern, Bern, Switzerland.

Before the advent of levodopa, pallidotomy was initially the most effective treatment for Parkinson disease, but it was soon superseded by thalamotomy. It is widely unknown that, similar to Leksell, 2 neurologists from Göttingen, Orthner and Roeder, perpetuated pallidotomy against the mainstream of their time. Postmortem studies demonstrated that true posterior and ventral pallidoansotomy sparing the overwhelming mass of the pallidum was accomplished. Read More

Bayesian adaptive dual control of deep brain stimulation in a computational model of Parkinson's disease.

PLoS Comput Biol 2018 12 6;14(12):e1006606. Epub 2018 Dec 6.

Department of Biomedical Engineering, University of Minnesota, Minneapolis, Minnesota, United States of America.

In this paper, we present a novel Bayesian adaptive dual controller (ADC) for autonomously programming deep brain stimulation devices. We evaluated the Bayesian ADC's performance in the context of reducing beta power in a computational model of Parkinson's disease, in which it was tasked with finding the set of stimulation parameters which optimally reduced beta power as fast as possible. Here, the Bayesian ADC has dual goals: (a) to minimize beta power by exploiting the best parameters found so far, and (b) to explore the space to find better parameters, thus allowing for better control in the future.

Is Transposition of Deep Brain Stimulation Device a Solution in Patients with Recurrent Skin Erosions?

Asian J Neurosurg 2018 Oct-Dec;13(4):1252-1253

Department of Neurosurgery, IRCCS Istituto Ortopedico Galeazzi, Milan, Italy.

Skin erosion and infection are common but serious problems in deep brain stimulation (DBS). They can lead to the removal of the entire DBS device and consequently stop the entire treatment. Of critical importance, therefore, is to find surgical solutions that allow to leave the complex DBS device in place when medical treatment fails in repeated skin complications, to allow continuing treatment in otherwise pharmacological refractory patients.

Method for localizing intraoperative recordings from deep brain stimulation surgery using post-operative structural MRI.

Neuroimage Clin 2018 16;20:1123-1128. Epub 2018 Oct 16.

Department of Neurosurgery, University of Colorado School of Medicine, Aurora, CO, United States. Electronic address:

Background: Implantation of deep brain stimulation (DBS) electrodes for the treatment of involuntary movement disorders, such as Parkinson's disease, routinely relies on the use of intraoperative electrophysiological confirmation to identify the optimal therapeutic target in the brain. However, only a few options exist to visualize the relative anatomic localization of intraoperative electrophysiological recordings with respect to post-operative imaging. We have developed a novel processing pipeline to visualize intraoperative electrophysiological signals registered to post-operative neuroanatomical imaging. Read More

Magnetic Resonance-Guided Focused Ultrasound in Neurosurgery: Taking Lessons from the Past to Inform the Future.

J Korean Med Sci 2018 Oct 4;33(44):e279. Epub 2018 Oct 4.

Department of Neurosurgery, Brain Research Institute, Yonsei University College of Medicine, Seoul, Korea.

Magnetic resonance-guided focused ultrasound (MRgFUS) is a new emerging neurosurgical procedure applied in a wide range of clinical fields. It can generate high-intensity energy at the focal zone in deep body areas without requiring incision of soft tissues. Although the effectiveness of the focused ultrasound technique had not been recognized because of the skull being a main barrier in the transmission of acoustic energy, the development of hemispheric distribution of ultrasound transducer phased arrays has solved this issue and enabled the performance of true transcranial procedures.

Etiology and Management of Spinal Deformity in Patients With Parkinson's Disease.

Int J Spine Surg 2018 Jan 30;12(1):15-21. Epub 2018 Mar 30.

Division of Spine Surgery, Department of Orthopaedic Surgery, Warren Alpert Medical School of Brown University, Providence, Rhode Island.

Patients with Parkinson's disease (PD) commonly develop severe spinal deformity, including scoliosis, antecollis, camptocormia, and Pisa syndrome. The etiology of PD-associated spinal deformity is not completely understood and in most cases is likely due to multiple interrelated factors, including central dystonia and focal myopathy. Once spinal deformity has occurred, surgery is often the only modality that can correct the condition, although control of the movement disorder through medication and deep brain stimulation may slow progression.
