BACKGROUND: Trunk flexion and axial extension are characteristic symptoms of chorea-acanthocytosis (ChAc). PHENOMENOLOGY SHOWN: A 41-year-old male with ChAc (confirmed by VPS13A mutations) reported that his involuntary axial movements were significantly ameliorated by either folding his arms over his chest or putting his hands behind his head. EDUCATIONAL VALUE: These apparent "sensory tricks" suggest a dystonic pathophysiology, and also merit further study to analyze their potential for symptom control in ChAc...

BACKGROUND: The aim was to assess incidence, prevalence and risk factors of medication-induced tremor in African-Caribbean patients with severe mental illness (SMI). METHOD: A prospective study of SMI patients receiving care from the only mental health service of the previous Dutch Antilles. Eight clinical assessments, over 18 years, focused on movement disorders, medication use, and resting tremor (RT) and (postural) action tremor (AT). Risk factors were modeled with logistic regression for both current (having) tremor and for tremor at the next time point (developing)...

BACKGROUND: The aim of this study was to determine whether tremor and bradykinesia impacted a dexterous activity performed by patients with essential tremor (ET). METHODS: Core bradykinesia was assessed in 27 controls and 15 patients with ET using a rapid alternating movement (RAM) task. Then, participants performed a "counting money" counting tasks while equipped with inertial measurement units to detect and quantify tremor during movement. The time required to perform subsections of the tasks and the rate of failure (errors) were compared between groups using Mann-Whitney U tests and a chi-square test, respectively...

BACKGROUND: Post-hypoxic myoclonus (PHM) is a syndrome that occurs when a patient has suffered hypoxic brain injury. The myoclonus is usually multifocal and generalized, often stemming from both cortical and subcortical origins. In severe cases, pharmacological treatments with antiepileptic medications may not satisfactorily control the myoclonus. METHODS: We present a case of a 23-year-old male with chronic medication refractory PHM following a cardiopulmonary arrest related to an asthmatic attack who improved with bilateral globus pallidus internus (GPi) deep brain stimulation (DBS)...

BACKGROUND: Sydenham's chorea (SC), the neurologic manifestation of rheumatic fever, remains the most prevalent form of chorea in children. Suggested treatments of chorea in SC include prophylactic penicillin, symptomatic (antipsychotic and anticonvulsant) medications, and immunomodulatory therapy (steroids, intravenous immunoglobulin (IVIG), and plasma exchange). In this manuscript, we undertook a systematic review of the published literature to examine the data supporting these therapeutic recommendations...

BACKGROUND: Tic disorders are generally considered to be of pediatric onset; however, reports of adult-onset tics exist in the literature. Tics can be categorized as either primary or secondary, with the latter being the larger group in adults. Primary or idiopathic tics that arise in adulthood make up a subset of tic disorders whose epidemiologic and clinical features have not been well delineated. METHODS: Articles to be included in this review were identified by searching PubMed, SCOPUS, and Web of Science using the terms adult- and late-onset tics, which resulted in 120 unique articles...

BACKGROUND: While there is no breakthrough progress in the medical treatment of essential tremor (ET), in the past decades several remarkable achievements happened in the surgical field, such as radiofrequency thalamotomy, thalamic deep brain stimulation, and gamma knife thalamotomy. The most recent advance in this area is magnetic resonance-guided focused ultrasound (MRgFUS). METHODS: The purpose of this review is to discuss the new developments and trials of MRgFUS in the treatment of ET and other tremor disorders...

BACKGROUND: High-frequency pallidal stimulation has been shown to improve various types of dystonia, including myoclonus-dystonia. CASE REPORT: We report a case of epsilon sarcoglycan mutation-negative myoclonus-dystonia with response to low-frequency bilateral pallidal stimulation. DISCUSSION: Low-frequency pallidal stimulation provides an effective means of treating various dystonias, regardless of genetic status, as in our case, as it provides increased programming options with fewer adverse effects...

BACKGROUND: Alien limb phenomenon occurs in 50-60% of patients with corticobasal syndrome (CBS) and usually presents with an "alien hand" phenomenon. The "alien foot" presentation is rarer and may be misdiagnosed, as foot involvement can lead to erroneous localization of the clinical problem to the knee, hip, or back. Subsequently misdiagnoses such as myelopathy, radiculopathy, functional disorder, stiff leg syndrome, neuromyotonia, and painful leg moving toes syndrome may occur. CASE REPORT: We describe two patients with alien foot symptoms that resulted in multiple opinions from different specialists, multiple diagnostic and therapeutic procedures, and delayed diagnosis...

BACKGROUND: Huntington disease is a fatal, autosomal dominant, neurodegenerative disorder manifest by the triad of a movement disorder, behavioral disturbances, and dementia. At present, no curative or disease modifying therapies exist for the condition and current treatments are symptomatic. Palliative care is an approach to care that focuses on symptom relief, patient and caregiver support, and end of life care. There is increasing evidence of the benefit of palliative care throughout the course of neurodegenerative conditions including Parkinson disease and amyotrophic lateral sclerosis...

BACKGROUND: Advances in molecular genetic technologies have improved our understanding of genetic causes of rare neurological disorders with features of myoclonus. CASE REPORT: A family with two affected siblings, presenting with multifocal polymyoclonus and neurodevelopmental delay, was recruited for whole-exome sequencing following unyielding diagnostic neurometabolic investigations. Compound heterozygous mutations in TBC1D24, a gene previously associated with various epilepsy phenotypes and hearing loss, were identified in both siblings...

CLINICAL VIGNETTE: A 67-year-old female with advanced Parkinson's disease (PD), medically refractory tremor, and a history of significant depression presented for evaluation of deep brain stimulation (DBS) candidacy. CLINICAL DILEMMA: Traditionally, the subthalamic nucleus (STN) has been preferred over the globus pallidus interna (GPi) as a DBS target for PD patients with levodopa-responsive fluctuations in rigidity and akinesia, for whom tremor is also a significant source of impairment...

REVIEW
Ludy C Shih, Alvaro Pascual-Leone
BACKGROUND: There is increasing interest in the use of non-invasive brain stimulation to characterize and potentially treat essential tremor (ET). Studies have used a variety of stimulation coils, paradigms, and target locations to make these observations. We reviewed the literature to compare prior studies and to evaluate the rationale and the methods used in these studies. METHODS: We performed a systematic literature search of the PubMed database using the terms "transcranial," "noninvasive," "brain stimulation," "transcranial magnetic stimulation (TMS)," "transcranial direct current stimulation (tDCS)," "transcranial alternating current stimulation (tACS)," and "essential tremor...

BACKGROUND: Classically, the onset of head tremor in essential tremor (ET) patients follows that of hand tremor, such that there is a somatotopic spread of involved areas. Here we present a series of seven self-reportedly "unaffected" relatives of ET cases. These seven were clinically asymptomatic and had normal levels of arm tremor on examination, yet each evidenced a transient head wobble on examination. We estimate the prevalence of this phenotype within the two studies from which cases were ascertained...

BACKGROUND: Deep brain stimulation (DBS) for essential tremor (ET) can cause unwanted side effects. CASE REPORT: A patient with ET underwent unilateral dual-lead thalamic DBS. He later developed parkinsonism with atypical features and was diagnosed with progressive supranuclear palsy. During presentation for a second opinion, stimulation-induced side effects were suspected. Inactivation of DBS resolved atypical features and superimposed idiopathic Parkinson disease (PD) was diagnosed...

BACKGROUND: There is a lack of evidence examining the role of physical therapy (PT) to address movement dysfunction for individuals with essential tremor (ET). CASE REPORT: A 61-year-old male with ET and prolonged bilateral deep brain stimulation (DBS) completed 14 sessions of outpatient PT that emphasized balance, functional movements, and proximal stability training with an integration of principles of body awareness training and visual motor coordination. Improvements were noted in all outcome measures...

BACKGROUND: Tourette syndrome (TS) has been described as peaking in adolescence with subsequent regression. We report patients who were diagnosed with TS during childhood who experienced a latent period (significant reduction in or absence of tics) followed by tic re-emergence in adulthood. METHODS: We performed a retrospective chart review of outpatients over age 21 seen at the Yale neurology clinic between January 2012 and July 2016 who were diagnosed with childhood-onset tics, and who experienced a latent period of greater than 1 year followed by an exacerbation...
