Essential tremor (ET) is among the most common neurological movement disorders that causes postural or action tremors, with an estimated prevalence nationwide of less than 3% of the population. The incidence of ET increases with age but often affects younger adults and has a familial trait association. Depending on disease progression, ET can cause significant limitations for individuals, in many cases, significantly limiting their ability to perform activities of daily living and occupational responsibilities...

Tremor is the most common movement deficit and manifests in a variety of disorders, including Essential Tremor, Parkinson's Disease, Dystonia, and Cerebellar Ataxia. Although medication and surgical interventions have significantly reduced patient suffering, they are only partially effective and can carry undesired side effects, leaving many patients without satisfactory treatment options. Wearable tremor-suppressing devices could provide an alternative to medication and surgery. Multiple research groups have developed orthotic prototypes to low-pass filter tremor, but these devices have not yet been optimized for in-vivo use...

BACKGROUND: Recent evidence suggests that glucosidase beta acid (GBA) mutations predispose Parkinson's disease (PD) patients to a greater burden of cognitive impairment and non-motor symptoms. This emerging knowledge has not yet been considered in patients who have undergone deep brain stimulation (DBS); a surgery that is generally contraindicated in those with cognitive deficits. OBJECTIVE: To explore the long-term phenotypic progression of GBA-associated PD, in a DBS cohort...

BACKGROUND: Emergence delirium is defined as a cognitive disturbance during emergence from general anesthesia resulting in hallucinations, delusions and confusion manifested by agitation, restlessness, involuntary physical movement and extreme flailing in bed. Postoperative emergence delirium develops in 12% to 18% of all children undergoing general anesthesia for surgery. This post-anesthetic phenomenon changes cognitive and psychomotor behavior, and puts pediatric patients and health care personnel at risk of injury...

Parkinson disease (PD) is increasingly prevalent in the aging population. Spine disorders in patients with PD may be degenerative in nature or may arise secondary to motor effects related to the parkinsonian disease process. Physicians providing care for patients with PD and spine pathologies must be aware of several factors that affect treatment, including the patterns of spinal deformity, complex drug interactions, and PD-associated osteoporosis. Following spine surgery, complication rates are higher in patients with PD than in those without the disease...

Context • Obstructive sleep apnea/hypopnea syndrome (OSAHS) is among the most prevalent of sleep-related breathing disorders. No long-term follow-up studies have documented the continued success of lifestyle changes in treatment; oral appliances have an approximate 50% success rate; compliance with continuous positive airway pressure is poor, ranging from 50% to 89%; and the success rate of upper-airway surgery is only 66.4%. Therefore, some OSAHS patients seek alternative treatments. Objectives • The study intended to examine the efficacy of traditional Chinese therapeutic massage (tui na) for patients with OSAHS...

BACKGROUND: Deep brain stimulation (DBS) has been proposed to treat patients with severe Tourette's syndrome, and open-label trials and two small double-blind trials have tested DBS of the posterior and the anterior internal globus pallidus (aGPi). We aimed to specifically assess the efficacy of aGPi DBS for severe Tourette's syndrome. METHODS: In this randomised, double-blind, controlled trial, we recruited patients aged 18-60 years with severe and medically refractory Tourette's syndrome from eight hospitals specialised in movement disorders in France...

BACKGROUND: Subthalamic stimulation improves the motor and neuropsychiatric symptoms of Parkinson's disease. However, the impact of this treatment on impulse control and personality is the subject of heavy debate. The objective of this study was to investigate personality changes after subthalamic stimulation. METHODS: Using Cloninger's biosocial model, we assessed personality in 73 Parkinson's disease patients before and 12 months after subthalamic stimulation accompanied by a drastic reduction in dopaminergic medication...

BACKGROUND: Efficacy in previous studies of surgical treatments of refractory multiple sclerosis tremor using lesioning or deep brain stimulation (DBS) has been variable. The aim of this study was to investigate the safety and efficacy of dual-lead thalamic DBS (one targeting the ventralis intermedius-ventralis oralis posterior nucleus border [the VIM lead] and one targeting the ventralis oralis anterior-ventralis oralis posterior border [the VO lead]) for the treatment of multiple sclerosis tremor...

OBJECT: Chronic neuropathic pain is estimated to affect 3-4.5% of the worldwide population, posing a serious burden to society. Deep Brain Stimulation (DBS) is already established for movement disorders and also used to treat some "off-label" conditions. However, DBS for the treatment of chronic, drug refractory, neuropathic pain, has shown variable outcomes with few studies performed in the last decade. Thus, this procedure has consensus approval in parts of Europe but not the USA. This study prospectively evaluated the efficacy at three years of DBS for neuropathic pain...

Although the use of ultrasound as a potential therapeutic modality in the brain has been under study for several decades, relatively few neuroscientists or neurologists are familiar with this technology. Stereotactic brain lesioning had been widely used as a treatment for medically refractory patients with essential tremor (ET), Parkinson disease (PD), and dystonia but has been largely replaced by deep brain stimulation (DBS) surgery, with advantages both in safety and efficacy. However, DBS is associated with complications including intracerebral hemorrhage, infection, and hardware malfunction...

Amyoplasia congenita, or "classic distal arthrogryposis," is the most common disorder among the congenital, non-progressive, multiple joint contractural conditions named arthrogryposis. The cause remains unknown, and it occurs sporadically. Abnormal neurological examination indicates that movement in utero was diminished as a result of an abnormality of the central or peripheral nervous system, the motor end plate, or muscle. The absence of central neural pathology indicates the origin in akinetic fetal condition...

The year 2017 marks the 70th anniversary of the birth of human stereotactic neurosurgery. The first procedure was a pallidotomy for Huntington's disease. However, it was for Parkinson's disease that pallidotomy was soon adopted worldwide. Pallidotomy was abandoned in the late 1950s in favor of thalamotomy because of the latter's more striking effect on tremor. The advent of levodopa put a halt to all surgery for PD. In the mid-1980s, Laitinen reintroduced the posteroventral pallidotomy of Leksell, and this procedure spread worldwide thanks to its efficacy on most parkinsonian symptoms including levodopa-induced dyskinesias and thanks to basic scientific work confirming the role of the globus pallidus internus in the pathophysiology of PD...

Cervical degenerative disease is one of the most common spinal disorders worldwide, especially in older people. Anterior cervical corpectomy and fusion (ACCF) is a useful method for the surgical treatment of multi-level cervical degenerative disease. Anterior cervical disc replacement (ACDR) is considered as an alternative surgical method. However, both methods have drawbacks, particularly the neck motion decrease observed after arthrodesis, and arthroplasty should only be performed on patients presenting with cervical disc disease but without any vertebral body disease...

BACKGROUND: Madelung's disease is a rare disorder characterised by the presence of multiple, symmetric, non-capsulated fat masses in the face, neck and other areas of upper extremities. In some cases, severe clinical complications such as upper airway compression can occur. CASE REPORT: A 56-year-old man affected by Madelung's disease complained of snoring and severe daytime sleepiness. Polysomnography revealed severe obstructive sleep apnoea. An attempt to treat sleep apnoea by continuous positive airway pressure failed because of poor compliance...

OBJECTIVE: Although performing deep brain stimulation (DBS) with the patient under general anesthesia without microelectrode recording (MER) or intraoperative test stimulation (ITS) for movement disorders ("asleep" DBS) has become increasingly popular, its feasibility is based on the untested assumption that stereotactic accuracy correlates with positive clinical outcomes. To investigate outcomes after asleep DBS without MER or neurophysiological testing, we reviewed the medical literature on the topic...

Parkinson's tremor is one of the cardinal motor symptoms of Parkinson's disease. The pathophysiology of Parkinson's tremor is different from that of other motor symptoms such as bradykinesia and rigidity. In this review, the authors discuss evidence suggesting that tremor is a network disorder that arises from distinct pathophysiological changes in the basal ganglia and in the cerebellothalamocortical circuit. They also discuss how interventions in this circuitry, for example, deep brain surgery and noninvasive brain stimulation, can modulate or even treat tremor...
