Functional Movement Disorders and Deep Brain Stimulation: A Multi-Center Study.

Background: Functional movement disorders (FMD) are a commonly under-recognized diagnosis in patients with underlying neurodegenerative diseases. FMD have been observed in patients undergoing deep brain stimulation (DBS) for Parkinson's disease (PD) and other movement disorders. The prevalence of coexisting FMD among movement disorder-related DBS patients is unknown, and it may occur more often than previously recognized.

Medical and Surgical Treatment for Medication-Induced Tremor: Case Report and Systematic Review.

Objective: To present a case of refractory medication-induced tremor successfully treated with deep brain stimulation (DBS) of the thalamic ventral intermediate nucleus (Vim) and to propose a medical and surgical treatment algorithm based on a systematical review of the literature.

Methods: Patient data were retrospectively collected. A systematic search was performed in PubMed, Embase, and Cochrane Library.

Management of Parkinson's Disease During Pregnancy: Literature Review and Multidisciplinary Input.

Background: There are no standardized clinical guidelines for the management of Parkinson's disease (PD) during pregnancy. Increasing maternal age would suggest that the incidence of pregnancy in women diagnosed with PD is likely to increase.

Objective: To evaluate the evidence for the treatment of PD during pregnancy and to canvass opinion from patients and clinical teams as to the optimum clinical management in this setting.

Skater's Cramp: A Possible Task-Specific Dystonia in Dutch Ice Skaters.

Background: Skater's cramp is an involuntary lower leg movement in skilled speed skaters. We aim to evaluate whether skater's cramp is compatible with task-specific dystonia.

Methods: A case-control study tested 5 speed skaters exhibiting symptoms of skater's cramp and 5 controls.

The Burke-Fahn-Marsden Dystonia Rating Scale is Age-Dependent in Healthy Children.

Background: The Burke-Fahn-Marsden Dystonia Rating Scale is a universally applied instrument for the quantitative assessment of dystonia in both children and adults. However, immature movements by healthy young children may also show "dystonic characteristics" as a consequence of physiologically incomplete brain maturation. This could implicate that Burke-Fahn-Marsden scale scores are confounded by pediatric age.
