Abstract
Musician's dystonia (MD) is a type of focal hand dystonia that develops only while playing musical instruments and interferes with skilled and fine movements. Lesioning of the ventro-oral (Vo) nucleus of the thalamus (Vo-thalamotomy) using radiofrequency can cause dramatic improvement in MD symptoms. Focused ultrasound (FUS) can make intracranial focal lesions without an incision. The authors used MRI-guided FUS (MRgFUS) to create a lesion on the Vo nucleus to treat a patient with MD. Tubiana's MD scale (TMDS) was used to evaluate the condition of musical play ranging from 1 to 5 (1: worst, 5: best). The patient was a 35-year-old right-handed man with involuntary flexion of the right second, third, and fourth fingers, which occurred while playing a classical guitar. Immediately after therapeutic sonications of FUS Vo-thalamotomy, there was dramatic improvement in the MD symptoms. The TMDS scores before; at 0 and 1 week after; and at 1, 3, 6, and 12 months after MRgFUS Vo-thalamotomy were 1, 4, 4, 5, 5, 5, and 5, respectively. No complications were observed. Focused ultrasound Vo-thalamotomy can be an effective treatment for MD.

Abstract
Non-ketotic hyperglycaemia (NKH) is the most common metabolic cause of hemichorea-hemiballismus (HC-HB) and an often-reversible condition. A 68-year-old man presented to the emergency department with a severe hyperglycaemic episode and altered mental status. He was treated appropriately and discharged home after his blood glucose levels were normal with an improvement of mental status. Four weeks after the discharge, he returned with flailing movements of bilateral upper and lower limbs. MRI of the brain revealed hyperintensities of the bilateral putamen on T1-weighted imaging. The patient's symptoms improved with a combination of amantadine, clonazepam and tetrabenazine. Several hypotheses involving gemistocytes, calcification and petechial haemorrhage were proposed in support of imaging abnormalities in the striatum. Dopamine-depleting agents and neuroleptics are used in the treatment of chorea. It is recommended to try a dose of tetrabenazine in patients with NKH-induced HC-HB if no improvement is appreciated with initial treatment of glycaemic control.

Abstract
Huntington's disease (HD) is an autosomal-dominant neurodegenerative disorder that has very few effective therapeutic interventions. Since the disease has a defined neural circuitry abnormality, neuromodulation could be an option. Case reports, original research, and animal model studies were selected from the databases of Medline and PubMed. All related studies published up to July 2014 were included in this review. The following search terms were used: "Deep brain stimulation," "DBS," "thalamotomy," "pallidal stimulation," and "Huntington's Disease," "HD," "chorea," or "hyperkinetic movement disorders." This review examines potential nodes in the HD circuitry that could be modulated using deep brain stimulation (DBS) therapy. With rapid evolution of imaging and ability to reach difficult targets in the brain with refined DBS technology, some phenotypes of HD could potentially be treated with DBS in the near future. Further clinical studies are warranted to validate the efficacy of neuromodulation and to determine the most optimal target for HD.

Abstract
Hemichorea-hemiballism is a rare movement disorder that has various causes. In treatment-resistant cases, both thalamic and pallidal functional procedures have been shown to yield beneficial results. Until now it has not been clarified whether the thalamus or the pallidum would yield a superior outcome. After resection of a craniopharyngioma in this patient at the age of 49 years, hemichorea-hemiballism developed, with a latency of several weeks. Because the patient was greatly impaired by the movement disorder, she underwent implantation of deep brain stimulation (DBS) electrodes in the thalamic ventralis intermedius nucleus and the posteroventral lateral globus pallidus internus. Although both pallidal and thalamic stimulation could suppress the movement disorder, the voltage needed was clearly less with thalamic than with pallidal stimulation. At the last available follow-up 25 months postoperatively, complete subsidence of hemichorea-hemiballism was achieved with long-term thalamic stimulation. Long-term DBS therapy is an efficient treatment modality for refractory hemichorea-hemiballism in the long run (> 2 years). A bifocal (thalamic and pallidal) target paradigm allowed selection of the optimal stimulation site. Thalamic DBS was more favorable with regard to energy consumption.

Abstract
Hemiballism is a relatively rare hyperkinetic movement disorder characterized by involuntary, violent, coarse and wide-amplitude movements involving ipsilateral arm and leg. Although classically related to lesions in the subthalamic nucleus, in clinical-radiological series of hemiballism most patients had lesions outside this nucleus, involving mainly other basal ganglia structures. It has been suggested that abnormal neuronal firing patterns in the internal segment of the globus pallidus may be related to the pathogenesis of hemiballism. Stroke is the most common cause, but in recent years an increasing number of patients with hemiballism associated with nonketotic hyperglycemia or with complications of human immunodeficiency virus (HIV) infection have been reported. Contrarily to what was stated in older literature, hemiballism has, in general, a relatively good prognosis. Depending on the underlying causes, many patients may experience spontaneous improvements or remissions. Treatment should be directed to the cause of hemiballism. Symptomatic treatment includes the use of drugs, particularly blockers of striatal D2 dopamine receptors and tetrabenazine. Surgical treatment, especially pallidotomy, is a therapeutic option for the minority of patients with severe persistent disabling hemiballism.

Abstract
Chorea may occur as part of the symptomatology of acute stroke; it occasionally also may be delayed or progressive. Patients with vascular-related chorea typically present with an acute or subacute onset of chorea of one side of the body (hemichorea), contralateral to the lesion. Cerebrovascular disease is the most common cause of sporadic chorea. Lesions are most frequently found in the thalamus and lentiform nucleus, and less often in subthalamic nucleus. The differential diagnosis of choreic syndromes relies not so much on differences in the phenomenology of the hyperkinesia but the age at onset, mode of onset, time course, family history, drug use, distribution of chorea in the body, and presence of accompanying neurological findings. Magnetic resonance imaging is preferred to demonstrate the presence of strategic small lesions in regions that are difficult to image with computed tomography, such as the globus pallidus, thalamus, and subthalamic nucleus. Although the prognosis of hemichorea can be benign, the long-term prognosis is not specifically determined by the hemichorea but by the long-term prognosis of stroke patients. Symptomatic treatment with antichoreic drugs may be necessary in the acute phase. Surgery is rarely indicated to treat vascular chorea.

Abstract
✓ The authors report a case of hemichorea—hemiballism (HC-HB) that was successfully treated using deep brain stimulation (DBS). A 65-year-old right-handed man exhibited a sudden onset of right HC-HB without a diabetic coma. At admission T1-weighted magnetic resonance (MR) images revealed a high-intensity signal in the left striatum, contralateral to the patient's involuntary movements.
The HC-HB continued for 5 months after onset of the condition despite medical treatment and a decreased intensity of the signal on T1-weighted MR images.
The patient underwent placement of a quadripolar DBS electrode in the left thalamus, including the left ventral oralis (VO) anterior and posterior nuclei (the VO complex). Postoperatively, the right-sided HC-HB disappeared rapidly during electrical stimulation and there were no neurological deficits.
The authors demonstrate that DBS can be an effective treatment for medically refractory HC-HB. This is the first case of HC-HB that has been successfully treated with DBS.

Abstract
We report on a 66-year-old woman in whom GPi pallidotomy produced progressive and eventually complete relief of hemichorea/ballism (HCB) after a subthalamic hemorrhage. Although choreoballistic movements were unchanged during and immediately after the surgery, the symptoms were gradually improved and consequently abolished by 5 days postoperatively. HCB has never recurred up to the present (9 months follow-up period). This note is the first report describing detailed postsurgical process in HCB relief after pallidotomy.

Abstract
Hemiballism is a rare movement disorder that presents with unilateral flinging movements of the limbs. In traditional teaching, it has been characterised as almost pathognomonic of a lesion in the subthalamic nucleus (STN). The prognosis was described as grave, with severe disability and death in many cases. However, review of more recent reports shows that the STN is directly involved in only a minority of cases. The prognosis is benign in most cases, with almost all patients responding well to treatment and many having spontaneous remission, although long-term prognosis of cerebrovascular disease may not be so good. There have also been recent insights into the pathophysiology of hemiballism, which have emphasised the importance of altered firing patterns in basal-ganglia structures. Recent studies have pointed to previously unrecognised causes, particularly non-ketotic hyperosmolar hyperglycaemia and complications of HIV infection, that may account for a substantial proportion of cases of hemiballism.

Abstract
The literature on thalamic surgery is difficult to read because different nomenclatures are in use. Neurosurgeons mostly use the stereotactic atlas of Schaltenbrand with Hassler's nomenclature of the thalamus. Neuroanatomists use different nomenclatures for the primate thalamus. The cytoarchitectonic definition of nuclei is difficult in the motor thalamus, and it would be best to define the nuclei based on their subcortical afferents. However, tracing studies are not available in humans. Thus, human thalamic nomenclature is based entirely on cytoarchitectonic subdivisions and transfer of knowledge by analogy from monkey to man. Problems arise when trying to transfer the detailed knowledge from monkey to the human brain. By doing so, different authors have come to different conclusions concerning the subcortical afferents of Hassler's motor nuclei, which inevitably leads to confusion when attempting neurophysiological interpretations of the surgical data. The present review draws attention to the discrepancies and open questions in the literature. There is a need to better define the limits of the sensory and cerebellar afferent receiving thalamic nuclei as well as those of the cerebellar and pallidal afferent receiving territories in humans.
