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 next chapter in symptomatic Parkinson disease treatments.

Parkinsonism Relat Disord 2019 Jan 3. Epub 2019 Jan 3.

Center for Neurological Restoration, Neurological Institute, Cleveland Clinic, Cleveland, OH, USA. Electronic address:

Significant advances in the symptomatic treatment of Parkinson disease (PD) have occurred since the discovery of levodopa (LD). Perhaps as a testament to its unparalleled efficacy, novel formulations aiming to optimize LD delivery to obtain better bioavailability, longer duration of effect and less plasma level fluctuations remain a major focus of drug development, nearly 5 decades since it was first commercially used. In addition, alternative apomorphine delivery formulations are also in development to provide rapid-acting, needle-free agents for the management of "off" episodes in patients experiencing motor fluctuations.

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the advent of levodopa, pallidotomy was initially the most effective treatment for Parkinson disease, but it was soon superseded by thalamotomy.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.

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.

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.

Among movement disorders and medicine in general, PD is one of the conditions for which there is a greater knowledge of the placebo and nocebo responses. In other movement disorders, the knowledge of placebo and nocebo responses is less. An advance in this field is expected to contribute to a better understanding of the nature of a therapeutic benefit in clinical research and clinical practice, and mechanisms of placebo and nocebo.

Patient-specific anatomical model for deep brain stimulation based on 7 Tesla MRI.

PLoS One 2018 22;13(8):e0201469. Epub 2018 Aug 22.

Center for Magnetic Resonance Research, Department of Radiology, University of Minnesota, Minneapolis, MN, United States of America.

Objective: Deep brain stimulation (DBS) requires accurate localization of the anatomical target structure, and the precise placement of the DBS electrode within it. Ultra-high field 7 Tesla (T) MR images can be utilized to create patient-specific anatomical 3D models of the subthalamic nuclei (STN) to enhance pre-surgical DBS targeting as well as post-surgical visualization of the DBS lead position and orientation. We validated the accuracy of the 7T imaging-based patient-specific model of the STN and measured the variability of the location and dimensions across movement disorder patients. Read More

Fortschr Neurol Psychiatr 2018 09 14;86(S 01):S5-S9. Epub 2018 Aug 14.

Parkinson-Klinik Ortenau, Wolfach.

Development of motor fluctuations and dyskinesia characterizes the transition from the early to the advanced Parkinson stage. Current oral therapeutic strategies aim at increasing the number of levodopa administrations and extending its benefit by the association of enzyme blockers (MAO- and COMT-inhibitors) and dopamine agonists. However, as disease progresses, mobility becomes progressively dependent on levodopa absorption and plasma bioavailability, resulting in disabling motor complications. Read More

Current surgical treatments for Parkinson's disease and potential therapeutic targets.

Neural Regen Res 2018 Aug;13(8):1342-1345

Division of Neurosurgery, Toronto Western Hospital, Department of Surgery, University of Toronto, Toronto, Canada.

Currently, the most common surgical treatment for Parkinson's disease is deep brain stimulation (DBS). This treatment strategy is typically reserved for bradykinesia, rigidity and tremor in patients who no longer respond to medication in a predictable manner or who suffer medication-induced dyskinesias. In addition to DBS, ablative procedures like radiofrequency, radiosurgery and focused ultrasound are also utilized for select tremor symptoms. Read More

Hormetic approaches to the treatment of Parkinson's disease: Perspectives and possibilities.

J Neurosci Res 2018 Oct 11;96(10):1641-1662. Epub 2018 Aug 11.

Environmental Health Sciences Division, School of Public Health, University of Massachusetts, Amherst, Massachusetts, USA.

Age-related changes in the brain reflect a dynamic interaction of genetic, epigenetic, phenotypic, and environmental factors that can be temporally restricted or more longitudinally present throughout the lifespan. Fundamental to these mechanisms is the capacity for physiological adaptation through modulation of diverse molecular and biochemical signaling occurring from the intracellular to the network-systemic level throughout the brain. A number of agents that affect the onset and progression of Parkinson's disease (PD)-like effects in experimental models exhibit temporal features, and mechanisms of hormetic dose responses.
