Movement disorders following mechanical thrombectomy resulting in ischemic lesions of the basal ganglia: An emerging clinical entity. Eur J Neurol 2024; 31:e16219.

Abstract
BACKGROUND AND PURPOSE Post-stroke movement disorders (PMDs) following ischemic lesions of the basal ganglia (BG) are a known entity, but data regarding their incidence are lacking. Ischemic strokes secondary to proximal middle cerebral artery (MCA) occlusion treated with thrombectomy represent a model of selective damage to the BG. The aim of this study was to assess the prevalence and features of movement disorders after selective BG ischemia in patients with successfully reperfused acute ischemic stroke (AIS). METHODS We enrolled 64 consecutive subjects with AIS due to proximal MCA occlusion treated with thrombectomy. Patients were clinically evaluated by a movement disorders specialist for PMDs onset at baseline, and after 6 and 12 months. RESULTS None of the patients showed an identifiable movement disorder in the subacute phase of the stroke. At 6 and 12 months, respectively, 7/25 (28%) and 7/13 (53.8%) evaluated patients developed PMDs. The clinical spectrum of PMDs encompassed parkinsonism, dystonia and chorea, either isolated or combined. In most patients, symptoms were contralateral to the lesion, although a subset of patients presented with bilateral involvement and prominent axial signs. CONCLUSION Post-stroke movement disorders are not uncommon in long-term follow-up of successfully reperfused AIS. Follow-up conducted by a multidisciplinary team is strongly advisable in patients with selective lesions of the BG after AIS, even if asymptomatic at discharge.

Abstract
Genetic testing has become a valuable diagnostic tool for movement disorders due to substantial advancements in understanding their genetic basis. However, the heterogeneity of movement disorders poses a significant challenge, with many genes implicated in different subtypes. This paper aims to provide a neurologist's perspective on approaching patients with hereditary hyperkinetic disorders with a focus on select forms of dystonia, paroxysmal dyskinesia, chorea, and ataxia. Age at onset, initial symptoms, and their severity, as well as the presence of any concurrent neurological and non-neurological features, contribute to the individual clinical profiles of hereditary non-parkinsonian movement disorders, aiding in the selection of appropriate genetic testing strategies. There are also more specific diagnostic clues that may facilitate the decision-making process and may be highly specific for certain conditions, such as diurnal fluctuations and l-dopa response in dopa-responsive dystonia, and triggering factors, duration and frequency of attacks in paroxysmal dyskinesia. While the genetic and mutational spectrum across non-parkinsonian movement disorders is broad, certain groups of diseases tend to be associated with specific types of pathogenic variants, such as repeat expansions in many of the ataxias. Some of these pathogenic variants cannot be detected by standard methods, such as panel or exome sequencing, but require the investigation of intronic regions for repeat expansions, such as Friedreich's or FGF14-linked ataxia. With our advancing knowledge of the genetic underpinnings of movement disorders, the incorporation of precise and personalized diagnostic strategies can enhance patient care, prognosis, and the application and development of targeted therapeutic interventions.

Abstract
Huntington disease (HD)-like 2 (HDL2) is a rare genetic disease caused by an expanded trinucleotide repeat in the JPH3 gene (encoding junctophilin 3) that shows remarkable clinical similarity to HD. To date, HDL2 has been reported only in patients with definite or probable African ancestry. A single haplotype background is shared by patients with HDL2 from different populations, supporting a common African origin for the expansion mutation. Nevertheless, outside South Africa, reports of patients with HDL2 in Africa are scarce, probably owing to limited clinical services across the continent. Systematic comparisons of HDL2 and HD have revealed closely overlapping motor, cognitive and psychiatric features and similar patterns of cerebral and striatal atrophy. The pathogenesis of HDL2 remains unclear but it is proposed to occur through several mechanisms, including loss of protein function and RNA and/or protein toxicity. This Review summarizes our current knowledge of this African-specific HD phenocopy and highlights key areas of overlap between HDL2 and HD. Given the aforementioned similarities in clinical phenotype and pathology, an improved understanding of HDL2 could provide novel insights into HD and other neurodegenerative and/or trinucleotide repeat expansion disorders.

Abstract
PURPOSE Diabetic striatopathy (DS) is a rare complication of poorly controlled diabetes mellitus (DM), characterized by hyperglycemia associated with chorea/ballism and characteristic reversible basal ganglia abnormalities on computed tomography (CT) and/or magnetic resonance imaging (MRI). We propose a narrative review of the literature on this topic, currently unknown to most, and about which physicians should be aware. We intend to summarize, critically review, and take to mean the evidence on this disorder, describing its typical features. METHODS We searched Pubmed for English-language sources using the following keywords in the title and the abstract: diabetic striatopathy, hyperglycemic non-ketotic hemichorea/hemiballism, chorea/hemichorea associated with non-ketotic hyperglycemia, diabetic hemiballism/hemichorea, chorea, hyperglycemia, and basal ganglia syndrome. We collected scientific articles, including case reports, reviews, systematic reviews, and meta-analyses from the years 1975 to 2023. We eliminated duplicate, non-English language or non-related articles. RESULTS Older Asian women are more frequently affected. Suddenly or insidiously hemichorea/hemiballism, mainly in the limbs, and high blood glucose with elevated HbA1c in the absence of ketone bodies have been observed. Furthermore, CT striatal hyperdensity and T1-weighted MRI hyperintensity have been observed. DS is often a treatable disease following proper hydration and insulin administration. Histopathological findings are variable, and no comprehensive hypothesis explains the atypical cases reported. CONCLUSION DS is a rare neurological manifestation of DM. If adequately treated, although treatment guidelines are lacking, the prognosis is good and life-threatening complications may occur occasionally. During chorea/hemiballism, we recommend blood glucose and HbA1c evaluation. Further studies are needed to understand the pathogenesis.

MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1949.

Abstract
Case report: An 83-year-old Italian female developed postural instability and gait disturbance associated with a concomitant hyperosmolar hyperglycemic state. Brain CT and MRI scans detected a lesion in the right putamen due to metabolic derangement. A month later, the patient started suffering from choreic movements along the left side of the body with brachio-crural distribution, approximately three weeks after SARS-CoV-2 infection. She was treated with tetrabenazine with complete resolution of the aberrant movements. Any attempt to reduce tetrabenazine caused a relapse of the symptoms. Discussion: In diabetic patients, choreic syndrome should be considered a rare event with a benign prognosis and favorable response to treatment. It is the result of a condition known as "diabetic striatopathy". The association of new-onset choreic movements, an episode of hyperglycemia, and a basal ganglia lesion is suggestive of this condition. Its pathophysiology remains unclear, and a lot of hypotheses are still debated. SARS-CoV-2 might have played a role in triggering the patient's motor symptoms. Conclusions: Our case report agrees with the general features of those reported in the literature about movement disorders in diabetic patients. The late onset of symptoms and the poor response to treatment seem to be atypical characteristics of the syndrome. Although speculative, we cannot exclude the role of SARS-CoV-2. This case can be added to the literature for further studies and reviews.

Abstract
Postinfectious neuroinflammation has been implicated in multiple models of acute-onset obsessive-compulsive disorder including Sydenham chorea (SC), pediatric acute-onset neuropsychiatric syndrome (PANS), and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS). These conditions are associated with a range of autoantibodies which are thought to be triggered by infections, most notably group A streptococci (GAS). Based on animal models using huma sera, these autoantibodies are thought to cross-react with neural antigens in the basal ganglia and modulate neuronal activity and behavior. As is true for many childhood neuroinflammatory diseases and rheumatological diseases, SC, PANS, and PANDAS lack clinically available, rigorous diagnostic biomarkers and randomized clinical trials. In this review article, we outline the accumulating evidence supporting the role neuroinflammation plays in these disorders. We describe work with animal models including patient-derived anti-neuronal autoantibodies, and we outline imaging studies that show alterations in the basal ganglia. In addition, we present research on metabolites, which are helpful in deciphering functional phenotypes, and on the implication of sleep in these disorders. Finally, we encourage future researchers to collaborate across medical specialties (e.g., pediatrics, psychiatry, rheumatology, immunology, and infectious disease) in order to further research on clinical syndromes presenting with neuropsychiatric manifestations.

Abstract
PURPOSE OF REVIEW Patients with different types of choreic syndromes, specially those with Huntington's (HD) and Wilson's (WD) diseases, report frequent sleep complaints. This review focuses on the main findings of studies addressing the sleep features in these diseases, and other less frequent causes of chorea associated with sleep disorders, including a new syndrome described in the last decade associated with IgLON5 antibodies. RECENT FINDINGS Patients with HD and WD showed a bad quality of sleep and high frequency of insomnia and excessive daytime somnolence. WD patients also showed high scores on a specific scale for rapid eye movement sleep behavior disorders. HD and WD share decreased sleep efficiency and increased REM sleep latencies, percentage of sleep stage N1, and wake after sleep onset (WASO) among their polysomnographic features. Patients with HD and WD showed a high prevalence of different sleep disorders. Patients with other causes of chorea, including neuroacanthocytosis, parasomnia with sleep breathing disorder associated with antibodies to IgLON5, Sydenham's chorea, and choreic syndromes associated to certain genetic mutations show sleep disorders as well.

Abstract
BACKGROUND Cerebral Palsy (CP) represents a frequent cause of disability in childhood. Early in life, genetic disorders may present with motor dysfunction and diagnosed as CP. Establishing the primary, genetic etiology allows more accurate prognosis, genetic counselling, and planning for symptomatic interventions in homogeneous etiological groups. Deep brain stimulation (DBS) is recommended in refractory movement disorders, including isolated pediatric dystonias. For dystonia evolving in more complex associations in genetic CP, the effect of DBS is still understudied and currently only sporadically described. OBJECTIVES To report the effect of DBS applied to the globus pallidus pars interna (GPi) in children with complex movement disorders caused by pathogenic ADCY5 variants, diagnosed as dyskinetic CP previous to genetic diagnostic. METHODS We conducted a retrospective study on evolution of treatment with DBS in ADCY5-related disease. A standardized proforma including the different type of movement disorders and associated neurological signs was completed at each follow-up time, based on video recordings, as well as functional assessments used in children with CP. RESULTS Four children (mean of age, 13 ± 2.9 years) received GPi-DBS. The same de novo pathogenic missense variant (c.1252C > T, p.R418W) was identified in three out of four and a splice site variant (c.2088 + 2G > T) in one subject. Developmental delay and overlapping features including axial hypotonia, chorea, dystonic attacks, myoclonus, and cranial dyskinesia were present. The median age at DBS was 9 years and follow-up with DBS, 2.6 years. We identified a pattern of clinical response with early suppression of dystonic attacks, followed by improvement of myoclonus and facial dyskinesia. Effect on chorea was delayed and more limited. Two patients gained notable functional benefit related to sitting, standing, gait, use of upper limbs and speech. CONCLUSION ADCY5-related disease may benefit from GPi-DBS. The most significant clinical response relates to the early and sustained benefit on dystonic attacks and a variable but still positive response on the other hyperkinetic features. Genetic etiology of CP will contribute to further elucidate genotype-phenotype correlations and to refine DBS indication as network-related symptomatic interventions.

Abstract
ABSTRACT Vitamin B12 deficiency may present with diverse symptoms, complicating the differential diagnosis. Extrapyramidal movement disorders, for instance, are a rare manifestation of vitamin B12 deficiency. MRI of the brain frequently remains without conclusive findings. However, 18 F-FDG PET/CT may reveal characteristic changes in the metabolism of the basal ganglia and thus contribute to an accurate diagnosis. We demonstrate the case of a woman with left-sided hemichoreatic movements due to vitamin B12 deficiency showing a contralateral putaminal hypermetabolism, which normalized after vitamin B12 supplementation, ruling out other deviating causes, particularly Huntington disease.

Abstract
We report a case of a patient who first presented with hyperglycemic chorea, and subsequently with hypoglycemic chorea. The patient's hypoglycemia was thought to be iatrogenic, highlighting the importance of careful glucose management following glycemia- related chorea. Presumably secondary to the patient's chorea, the patient also suffered from new onset shoulder pain, which was managed with gabapentin. Unfortunately, due to the patient's renal failure, the gabapentin, combined with infection, led to encephalopathy in this patient. This report presents and offers useful tips on the management of a unique patient who suffered from hyperglycemic chorea, hypoglycemic chorea, and encephalopathy, all within a few weeks.

Abstract
A previously healthy 8-year-old Native American female presented with right-sided weakness and joint pain for two weeks. Following an initially unremarkable workup including negative brain and spine MRI she was noticed to have chorea and subsequently diagnosed with acute rheumatic fever (ARF). ARF is a group A streptococcus-related disease that most commonly is a sequelae of pharyngitis. The diagnosis of ARF utilizes the Jones criteria which includes heart disease, arthritis, chorea, the characteristic rash of erythema marginatum, and subcutaneous nodules. The most serious consequences of ARF include rheumatic heart disease and chorea. ARF can be treated with a combination of antibiotics and anti-inflammatories like aspirin.

Abstract
Cerebral infarction as well as other thromboses, headaches, and visual complaints are well-known symptoms of polycythemia vera. However, chorea and neuropsychiatric disturbances are less recognized consequences of this chronic disease. Whereas chorea is a rare but acknowledged symptom of polycythemia vera, neuropsychiatric symptoms have only sporadically been reported. We depict 2 patients with an unusual presentation of polycythemia vera. Our first patient presented with right-sided hemiballism and psychosis, and the second patient had a long diagnostic trajectory of unexplained chorea. In both cases diagnosis of JAK2 positive polycythemia vera was established, and in both cases remarkable recovery occurred after the initiation of phlebotomies. The underlying pathophysiology of these symptoms has not been clearly elucidated. Because of the unfamiliarity of the link between especially neuropsychiatric symptoms and polycythemia, current reported numbers are probably an underestimation. Benefit of treatment appears to be large. We seek to create more awareness among physicians about this phenomenon.

Abstract
Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis is one of the most common causes of autoimmune encephalitis. Both movement disorders and neuropsychiatric manifestations are considered core features of anti-NMDAR encephalitis. Strong clinical suspicion, along with NMDAR antibody positivity in paired sample of serum and cerebrospinal fluid, with supportive MRI changes clinch diagnosis in majority. We herein report a case of a middle-aged woman with subacute behavioral abnormalities, which were so severe that forced her to attempt suicide. Hemichorea and dystonia, which appeared later in course, are not previously reported movement disorders in combination in anti-NMDAR encephalitis. Further, magnetic resonance imaging showed bilateral thalamic hyperintensities with diffusion restriction, which are in turn not described in this entity. After amalgamation of history, especially the presence of neuropsychiatric symptoms, clinical features, physical examination, and investigations, the diagnosis of anti-NMDAR encephalitis could be established. Our case not only highlights that the combination of hemichorea and dystonia can be features of anti-NMDAR encephalitis, but adds novelty by bilateral symmetric thalamic changes.

Abstract
RATIONALE Hemichorea-hemiballism, a rare manifestation of non-ketotic hyperglycemia, characterized by involuntary arrhythmic motions involving one side of the body, results from focal lesions in the contralateral caudate nucleus and putamen. Hyperkinetic disorders can be complications of uncontrolled diabetes mellitus and should not be ignored. PATIENT CONCERNS We present the case of a 39-year-old woman who presented to the emergency department with a 3-day history of left-sided hemichorea-hemiballism. She had type 2 diabetes mellitus with poor control and maintenance of regular hemodialysis. DIAGNOSES The patient was diagnosed as hyperglycemia, normal ketone body and hemichorea-hemiballism based on laboratory examination, computed tomography (CT) scan, and brain magnetic resonance image (MRI). INTERVENTIONS Intensive glycemic control via insulin injection was prescribed for correction of hyperglycemia. OUTCOMES The unilateral involuntary movements subsided progressively over four weeks. The patient's hemichorea had completely resolved at the three-month follow-up. LESSONS This unusual clinical presentation is often accompanied by severe hyperglycemia. Appropriate blood glycemic control is important. If physicians recognize and provide early treatment for this disease, it is usually treatable and has a good prognosis.

Abstract
INTRODUCTION This is a unique case of nonketotic hyperglycemic (NKH) chorea in 84-year-old Asian woman. The patient had a history of type 2 diabetes mellitus more than 30 years, but had a poor control of blood sugar. She complained of acute onset of bilateral limb involuntary activities, and being easy to fall within a week. Laboratory testing disclosed hyperglycemia (669 mg/dL), glycated hemoglobin (14%), and normal ketones. The brain computed tomography scan and magnetic resonance imaging did not disclose any abnormality in the basal ganglion unlike most cases. The patient was then diagnosed with NKH chorea. Her symptoms improved quickly. CONCLUSIONS NKH chorea with normal imaging may represent a new subtype.

Abstract
Chorea-acanthocytosis is an uncommon neurodegenerative disorder. Early diagnosis is often challenging. The triad of orofacial dyskinesia, epileptic seizures, and hyperCKemia should alert neurologists of a neuroacanthocytosis syndrome. The diagnosis can be confirmed by detection of chorein deficiency or through molecular genetics (VPS13A mutation).

Abstract
BACKGROUND Diabetic striatopathy (DS) is a rare complication of diabetes mellitus (DM). The syndrome appears in patients with uncontrolled DM and is characterized by abrupt onset of movement disorder, mainly hemichorea and accompanied by specific findings on brain imaging. It is believed that DS is unique to the Asian population and affects mainly elderly women with uncontrolled DM. METHODS In order to define existence and characterization of DS in Western population, we reviewed the medical records of all patients admitted to the Chaim Sheba Medical Center between 2004 and 2014 and identified those with documented elevated HbA1c (>10%). The charts and imaging studies of those with elevated HbA1c and undiagnosed neurological symptoms were reviewed to diagnose DS. RESULTS Out of 697 patients with HbA1c>10%, 328 patients had unknown neurological diagnosis. Among them, we identified 4 patients (3 women, mean age 73 and mean HbA1c of 14.8%) with hemichorea or choreoathetosis and brain imaging findings compatible with the diagnosis of DS. Only one out of the 4 patients was diagnosed during hospitalization with DS. All patients were treated with insulin with improvement of their symptoms during hospitalization. However, there was a recurrence in 2 of them and 1 died during the second episode. CONCLUSION Diabetic striatopathy exists but underdiagnosed in the Western population. It is important to increase the awareness for this clinical syndrome in order to treat those patients properly.

Abstract
BACKGROUND Chorea is a rare complication of uncontrolled type II diabetes. We report for the first time in Tanzania a case of type II diabetes presenting with a hyperglycaemia-induced hemichorea. CASE PRESENTATION A 58-year-old Tanzanian chagga by tribe with a body mass index of 28 kg/m(2) and newly diagnosed type II diabetes presented with polydipsia and involuntary movements of the right upper limb for 4 days. His plasma glucose was 549 mg/dl and glycated haemoglobin was 18.9 %. His movements were exaggerated by attempts to use his right hand. The rest of his neurological assessment was unremarkable. Other laboratory findings including calcium were within the normal range. A computed tomography scan of the brain was essentially normal except for age-related atrophy. There was no significant ketonuria on urine dipstick testing. We treated the patient's hyperglycaemia with intravenous insulin and the dystonia disappeared within 5 days. CONCLUSION Hemichorea is among the rare complications of hyperglycaemia-induced involuntary movements. Hyperglycaemia should be considered as a differential diagnosis for patients with type II diabetes mellitus presenting with hemichorea upon clinical assessment.
