ACR Appropriateness Criteria® Ataxia-Child. J Am Coll Radiol 2022; 19:S240-S255.

Abstract
Childhood ataxia may be due to multifactorial causes of impairment in the coordination of movement and balance. Acutely presenting ataxia in children may be due to infectious, inflammatory, toxic, ischemic, or traumatic etiology. Intermittent or episodic ataxia in children may be manifestations of migraine, benign positional vertigo, or intermittent metabolic disorders. Nonprogressive childhood ataxia suggests a congenital brain malformation or early prenatal or perinatal brain injury, and progressive childhood ataxia indicates inherited causes or acquired posterior fossa lesions that result in gradual cerebellar dysfunction. CT and MRI of the central nervous system are the usual modalities used in imaging children presenting with ataxia, based on the clinical presentation. This document provides initial imaging guidelines for a child presenting with acute ataxia with or without a history of recent trauma, recurrent ataxia with interval normal neurological examination, chronic progressive ataxia, and chronic nonprogressive ataxia. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
Background: Autosomal recessive cerebellar ataxias (ARCAs) are a heterogeneous group of inherited neurodegenerative disorders. The aim of this study was to present the clinical and genetic features of patients with ataxia complaints and those genetically diagnosed with ARCAs. Materials and Methods: Thirty-one children with ARCA were retrospectively analyzed. Results: Fourteen (45.2%) were boys and 17 (54.8%) were girls with the mean age at onset of symptoms of 46.13 ± 26.30 months (12–120 months). Of the 31 patients, 21 (67.7%) were from consanguineous marriages. Eight patients had Friedreich’s ataxia, five had ataxia telangiectasia, three had L-2-hydroxyglutaric aciduria, three had Joubert syndrome, two had neuronal ceroid lipofuscinosis, two had megalencephalic leukoencephalopathy with subcortical cysts, two had ataxia with ocular motor oculomotor apraxia type 1, one had cytochrome c oxidase deficiency, one had autosomal recessive spastic ataxia of Charlevoix-Saguenay, one had Niemann-Pick type C, one had congenital disorders of glycosylation, one had adrenoleukodystrophy, and one had cobalamin transport disorder. Conclusion: The prevalence of hereditary ataxia can vary among countries. The consanguineous marriage is an important finding in these diseases. These genetic tests will increase the number of ARCA patients diagnosed.

Genetic and phenotypic features of patients with childhood ataxias diagnosed by next-generation sequencing gene panel. Brain Dev 2020; 42:6-18. [PMID: 31493945 DOI: 10.1016/j.braindev.2019.08.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2018] [Revised: 08/15/2019] [Accepted: 08/19/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND The purpose of this prospective study was to identify the characteristics of pediatric recessive ataxias and the mutations leading to them. METHODS Eighty-four pediatric patients aged 0-18 years presenting to our clinic, evaluated by means of imaging, metabolic or pathological investigation, or single-gene test, in whom Friedreich's ataxia was excluded, and predicted to carry the progressive autosomal recessive ataxia gene were included in the study. Patients' demographic, clinical, laboratory, and radiological characteristics were recorded. DNA and panel sequencing directed toward ataxia-related genes was performed using the next-generation sequencing method. RESULTS A molecular diagnosis was established in 21 (25%) of the 84 patients. Genetically, infantile neuroaxonal dystrophy (7/21), ataxia with oculomotor apraxia type 1 (5/21), neuronal ceroid lipofuscinosis type 5 (2/21), ataxia with oculomotor apraxia type 2 (1/21), Lafora disease (1/21), tremor ataxia syndrome accompanying central hypomyelination (1/21), Charlevoix-Saguenay ataxia (1/21), Marinesco-Sjögren syndrome (1/21), VLDRL-associated cerebellar hypoplasia (1/21), and TSEN54-related pontocerebellar hypoplasia (1/21) mutations were detected. CONCLUSIONS Approximately 25% of our patients were diagnosed. Novel mutations in the known genes were identified and are important in terms of phenotype-genotype correlation.
