Abstract
BACKGROUND The evidence in the effectiveness of deep brain stimulation in children with medication-refractory non-degenerative monogenic dystonia is heterogeneous and long-term results are sparse. OBJECTIVES The objective is to describe long-term outcomes in a single-center cohort and compare our results with a meta-analysis cohort form literature. METHODS We performed a retrospective single-center cohort study including consecutive pediatric patients with non-degenerative genetic or idiopathic dystonia treated with globus pallidus internus deep brain stimulation at our center and a systematic review and individual-patient data meta-analysis with the same inclusion criteria. The primary outcome was the change from baseline in the Burke-Fahn-Marsden Dystonia Rating Scale-movement (BFMDRS-M) score. RESULTS The clinical cohort included 25 patients with a mean study follow-up of 11.4 years. The meta-analysis cohort included 224 patients with a mean follow-up of 3 years. Overall, the BFMDRS-M mean improvements at 1 year and at last follow-up were 41% and 33% in the clinical cohort and 58.9% and 57.2% in the meta-analysis cohort, respectively. TOR1A-dystonia showed the greatest and most stable BFMDRS-M improvement in both cohorts at 1 year and at last follow-up (76.3% and 74.3% in the clinical cohort; 69.6% and 67.3% in the meta-analysis cohort), followed by SGCE-dystonia (63% and 63.9% in the meta-analysis cohort). THAP1-dystonia (70.1% and 29.8% in the clinical cohort; 52.3% and 42.0% in the meta-analysis cohort) and KMT2B-dystonia (33.3% and 41.3% in the clinical cohort; 38.0% and 26.7% in the meta-analysis cohort) showed a less pronounced or sustained response. CONCLUSION Globus pallidus deep brain stimulation long-term treatment seems effective with a possible gene-specific differential effect. © 2024 The Authors.

Abstract
Movement disorders in a pediatric population represent a spectrum of secondary functional deficits affecting ease of care, ambulation, and activities of daily living. Cerebral palsy represents the most common form of movement disorder seen in the pediatric population. Several medical and surgical options exist in the treatment of pediatric spasticity and dystonia, which can have profound effects on the functionality of these patients. Given the complex medical and surgical problems in these patients, children are well served by a multidisciplinary team of practitioners, including physical therapists, physical medicine and rehabilitation physicians, and surgeons.

Abstract
OBJECTIVE To describe the frequency, motor phenotype, clinical patterns and functional consequences of dystonia in patients with cerebral palsy (CP) in the setting of periventricular leukomalacia. METHODS Retrospective analysis of a cohort of 31 patients with CP and periventricular leukomalacia. Gross Motor Function Classification System (GMFCS) and Manual Ability Classification System (MACS) were used to classify functional ability. Spasticity was rated using the Modified Ashworth Scale. Presence of dystonia was assessed by reviewing video recordings, and its severity by using the Burke-Fahn-Marsden Dystonia Rating Scale. RESULTS All patients showed evidence of dystonia involving upper and/or lower limbs, neck, trunk, mouth and eyes in order of frequency. In 29% of patients dystonia involved only the limbs and in 71% it was multifocal. Dystonia severity ranged from slight to severe. Severity and distribution of dystonia did not correlate with gender, age, weeks of gestation or duration of neonatal unit stay. GMFCS and MACS correlated with dystonia but not with spasticity. CONCLUSIONS Severity of dystonia, but not spasticity is associated with the severity of motor functional disability in CP patients with periventricular leukomalacia and demonstrates the key role of dystonia in the motor function of these patients.

Abstract
BACKGROUND In order to distinguish seizure mimics from seizures in children it is important to clarify the event duration, frequency, semiology, and any precipitating factors. METHODOLOGY This review provides a succinct and up-to-date overview aimed at general and subspecialty non-neurologist pediatric and adolescent health care providers to help guide a diagnostic approach when a child presents with paroxysmal events of unclear etiology. RESULTS In many cases, seizure mimics are consistently triggered by an event, location, or emotion, and often resolve with distraction or tactile stimulation. Suspicion should be raised for seizures when events occur out of deep sleep, there is a loss of consciousness with the event, movements are not suppressible, and there is a period of fatigue afterword (minutes to hours). Further, a past medical history of developmental delay (e.g. autism), developmental regression, or neurologic injury increases patients' risk for seizures. CONCLUSIONS Common seizure mimics are highlighted in the age group in which they are most prevalent.

Abstract
Neurodegenerative disorders include a group of severe diseases that share a core including a gradual loss of previously acquired motor, sensory and cognitive functions. In pediatric age, the main diagnostic issues are the discrimination between the loss of previously acquired competencies and the lack of achievement of specific developmental milestones. An ideal classification of these disorders could be based on the combination of genetic, clinical and neuroimaging features. Diagnostic workup should be organized with a special attention to the few diseases with an available and effective therapeutic treatment. The present paper reports a proposal of classification that is based on the prominently involved structure and summarizes the hallmarks for clinical approach and therapeutic management.

Abstract
PURPOSE OF REVIEW This article provides an overview of the clinical features and disorders associated with movement disorders in childhood. This article discusses movement disorder phenomena and their clinical presentation in infants and children and presents a diagnostic approach to suspected genetic disorders with a focus on treatable conditions. RECENT FINDINGS Technologic advances in molecular genetic testing over the past decade continue to lead to the discovery of new diseases. This article discusses the clinical presentation and early experience with treatment for several recently described genetic forms of infantile-onset and childhood-onset dystonia and chorea. SUMMARY The clinical spectrum of pediatric movement disorders is broad and heterogeneous, ranging from acute or transient self-limited conditions to conditions that cause profound lifelong motor disability. Most movement disorders in childhood are chronic, and the large number of rare, genetic conditions associated with pediatric movement disorders can pose a significant diagnostic challenge. Recognition of distinctive diagnostic clues in the history and examination can facilitate the diagnosis of potentially treatable disorders.
