Wilson’s disease is an autosomal–recessive disorder of copper metabolism caused by mutations in ATP7B and associated with neurological, psychiatric, ophthalmological and hepatic manifestations. Decoppering treatments are used to prevent disease progression and reduce symptoms, but neurological outcomes remain mixed. In this article, we review the current understanding of pathogenesis, biomarkers and treatments for Wilson’s disease from the neurological perspective, with a focus on recent advances. The genetic and molecular mechanisms associated with ATP7B dysfunction have been well characterised, but despite extensive efforts to identify genotype–phenotype correlations, the reason why only some patients develop neurological or psychiatric features remains unclear. We discuss pathological processes through which copper accumulation leads to neurodegeneration, such as mitochondrial dysfunction, the role of brain iron metabolism and the broader concept of selective neuronal vulnerability in Wilson’s disease. Delayed diagnoses continue to be a major problem for patients with neurological presentations. We highlight limitations in our current approach to making a diagnosis and novel diagnostic biomarkers, including the potential for newborn screening programmes. We describe recent progress in developing imaging and wet (fluid) biomarkers for neurological involvement, including findings from quantitative MRI and other neuroimaging studies, and the development of a semiquantitative scoring system for assessing radiological severity. Finally, we cover the use of established and novel chelating agents, paradoxical neurological worsening, and progress developing targeted molecular and gene therapy for Wilson’s disease, before discussing future directions for translational research.

AbstractWilson’s disease is an autosomal-recessive disorder caused by mutation in the ATP7B gene. Absent or reduced function of ATP7B protein leads to decreased hepatocellular excretion of copper into bile. Subsequent copper accumulation, first in the liver but ultimately in the brain and other tissues, produces different clinical manifestations such as hepatic, neurological, hematological, ophthalmological, and psychiatric problems. Diagnosis is based on clinical suspicion, parameters of copper metabolism, ophthalmic examination (Kayser-Fleischer rings) and a liver biopsy. Genetic studies are of limited use. Early diagnosis and initiation of therapy with chelators and therapeutic plasma exchange therapy are essential for prognosis. Liver transplantation corrects the underlying pathophysiology and can be lifesaving in fulminant hepatic failure. Screening of siblings and 1st degree relatives of the patients is also important.

Abstract Background Wilson’s disease is a rare autosomal recessive disorder affecting copper metabolism, which presents liver and brain dysfunction caused by abnormal copper accumulation. We report a patient who showed exacerbation of liver failure during pregnancy. Case presentation A 24-year-old woman with Wilson’s disease was scheduled for emergency cesarean delivery at 30 weeks of gestation. The patient exhibited severe coagulopathy and prominent body weight gain (+ 30 kg) caused by systemic edema and ascites. We decided to perform emergency cesarean delivery under general anesthesia. We used platelet concentrates, cryoprecipitate, and fibrinogen concentrate. Intraoperative hemorrhage was well controlled. On the 15th postpartum day, weight was reduced by 20 kg and liver function had improved. She and her baby were discharged without complications. Conclusions The appropriate continued treatment of Wilson’s disease and supplementation of coagulation factors and/or platelets when indicated greatly increase the likelihood of a successful pregnancy, even in patients with liver failure exacerbation.

Wilson's disease in an autosomal recessive disorder of copper metabolism where systemic manifestations are secondary to thei accumulation of copper in hepatic, nervous and other tissues. In CNS, the structural lesions most commonly found by CT scan are ventricular dilatation, cortical atrophy, basal ganglia hyperdensities, and brainstem and cerebellar atrophy. Degenerative changes of cerebral white matter seen on early anatomo-pathologic studies, but were almost never found on CT scan from recently described patients. We report a case of Wilson's disease with an unusually rapid deterioration where asymmetric low-densities in the subcortical white matter were disclosed by CT scan.

Wilson's disease (WD) is an autosomal recessive disorder of copper metabolism with an incidence of about 30 per million (i.e. fewer than 2,000 in the UK). Nevertheless, it is important for two main reasons: its manifestations are protean and may lead it to present to a range of specialists; and its otherwise lethal course can be halted by treatment with chelating agents such as penicillamine and trientine. Published cases and systematic study have shown that neuropsychiatric symptomatology is important in a high proportion. In fact, about one-fifth either present psychiatrically or are at least seen by a psychiatrist before WD is diagnosed.

Wilson’s disease is an autosomal recessive disorder caused by mutations in the ATP7B gene, a membrane-bound copper-transporting ATPase. Clinical manifestations are caused by copper toxicity and primarily involve the liver, the brain and the eye. Because effective treatment is available, it is important to make this diagnosis early. We report a patient who developed features of neurological and ocular manifestations: incoordination and tremor and blurring of vision with presence of Kayser-Fleischer ring circling the cornea but no signs of hepatic dysfunction.

Abstract Hepatolenticular degeneration, also known as Wilson's disease, is an autosomal recessive disorder of copper metabolism that causes rare diseases with significant morbidity and mortality. To our knowledge, no cases of hepatolenticular degeneration with massive cerebral infarction have been reported up to now. Here we present a case of hepatolenticular degeneration with massive cerebral infarction. Early, appropriate diagnosis and initiation of proper therapy could avoid further progression and reduce complications of the disease.

Introdução: A neuropatia periférica é um distúrbio neurológico bastante comum e vem aumentando sua prevalência devido ao processo de envelhecimento da população e aumento de comorbidades como diabetes e obesidade. A neuropatia periférica de fibras finas (NFF) é considerada uma síndrome que apresenta manifestações sensitivas isoladas, ou a combinação de manifestações sensitivas e autonômicas. A doença de Wilson (DW) é um transtorno autossômico recessivo causado por deficiência na metabolização do cobre decorrente de mutações no gene ATP7B. Entre as alterações neurológicas apresentadas pelos pacientes com DW está a neuropatia periférica. Objetivo: Revisar a literatura acerca da neuropatia de fibras finas na Doença de Wilson aumentando a compreensão dessa disfunção sobre suas causas e tipos de abordagens apresentadas na literatura. Métodos: Foi realizada uma revisão bibliográfica a partir do levantamento de dados presente nas bases de dados Scielo e PUBMED no período de janeiro a junho de 2021, utilizando os descritores: “Small Fiber Neuropathy”, “Wilson’s Disease”, “Peripheral Neuropathy". Resultados: Foram selecionados 29 artigos, cujos originais foram utilizados para composição deste estudo. Para melhor compreensão, os resultados encontrados no levantamento bibliográfico foram divididos em tópicos. Dos 29 artigos recrutados 15 foram excluídos, pois apresentavam outras doenças de base que pudessem justificar a presença de neuropatia além da doença de Wilson. Dos 14 artigos incluídos na pesquisa: 3 descreveram a presença de neuropatia de fibras finas na DW, 4 artigos destacaram a presença de leve polineuropatia sensitivo motora axonal na DW, 7 artigos mostraram evidência de neuropatia autonômica, sendo 2 com disfunção predominantemente simpática e 1 parassimpática.  Conclusão: Neuropatia de fibras finas permanece como um diagnóstico desafiador na literatura, podendo estar presente em formas leves, mesmo em doenças com envolvimento predominante do SNC. Na DW também há relatos desse acometimento neurológico periférico, com predomínio de envolvimento de fibras finas autonômicas de repercussões ainda não completamente compreendidas. A compreensão dessa disfunção ainda não está totalmente esclarecida e ainda há muitas coisas a serem compreendidas sobre a doença de Wilson, portanto faz-se necessário mais estudo sobre essa temática uma vez que ainda é escasso na literatura estudos que abordem esse assunto mesmo havendo aumento do número de casos diagnosticados com doença de Wilson e que apresentam queixas sensitivas associadas. Palavras chave: Neuropatia de fibras finas, Doença de Wilson, Doenças do sistema nervoso periférico, Neuropatias periféricas   Abstract Introduction: Peripheral neuropathy is a very common neurological disorder and its prevalence is increasing due to the aging process of the population and the increase in comorbidities such as diabetes and obesity. Fine fiber peripheral neuropathy (NFF) is considered a syndrome that presents isolated sensory manifestations, or a combination of sensory and autonomic manifestations. Wilson's disease (WD) is an autosomal recessive disorder caused by impaired copper metabolism due to mutations in the ATP7B gene. Among the neurological alterations presented by patients with WD is peripheral neuropathy. Objective: To review the literature about thin fiber neuropathy in Wilson's Disease, increasing the understanding of this dysfunction about its causes and types of approaches presented in the literature. Methods: A literature review was carried out based on the data survey present in the Scielo and PUBMED databases from January to June 2021, using the descriptors: "Small Fiber Neuropathy", "Wilson's Disease", "Peripheral Neuropathy". Results: 29 articles were selected, whose For a better understanding, the results found in the literature review were divided into topics.From 29 recruited articles, 15 were excluded, as they had other underlying diseases that could justify the presence of neuropathy in addition to Wilson's disease. Of the 14 articles included in the research: 3 described the presence of fine fiber neuropathy in WD, 4 articles highlighted the presence of mild axonal sensory motor polyneuropathy in WD, 7 articles showed evidence of autonomic neuropathy, 2 with predominantly sympathetic dysfunction and 1 parasympathetic. Conclusion: Fine fiber neuropathy remains a challenging diagnosis in the field. and may be present in mild forms, even in diseases with predominant involvement of the CNS. In WD there are also reports of this peripheral neurological involvement, with a predominance of involvement of thin autonomic fibers with repercussions that are not yet completely understood. The understanding of this dysfunction is still not fully clarified and there are still many things to be understood about Wilson's disease, so further study on this topic is necessary since studies addressing this issue are still scarce in the literature, even with an increase in number of cases diagnosed with Wilson's disease and presenting associated sensory complaints. Keywords: Small fiber neuropathy, Wilson disease, Peripheral nervous system diseases, Peripheral neuropathies

Wilson's disease is an autosomal-recessive disorder of copper metabolism resulting from the absence or dysfunction of a copper-transporting protein. The disease is mainly seen in children, adolescents and young adults, and is characterized by hepatobiliary, neurologic, psychiatric and ophthalmologic (Kayser-Fleischer rings) manifestations. Mechanism of status dystonicus in WD is not clear. We present here a case study of Wilson’s disease in 14 year old child with dystonia not responded with routine therapy.Journal of Advances in Internal Medicine 2014;3(2):62-64

Rickets is a disease of bone mineralization of growth plate. Refractory rickets can be caused by distal (type 1) renal tubular acidosis (RTA). A number of conditions can result in distal RTA and Wilson’s disease is an uncommon entity. Wilson’s disease is a rare autosomal recessive disorder of copper metabolism with diverse presentations. We describe a case of refractory rickets due to distal RTA, caused by Wilson’s disease. Diagnosis of Wilson’s disease was confirmed with presence of Kayser–Fleischer (K–F) rings and high urinary copper. Further investigations revealed urinary acidification defect with hypercalciuria pointing towards distal RTA. He was treated with penicillamine & oral Zinc and significant clinical improvement was observed.Bangladesh J Medicine Jul 2018; 29(2) : 84-86

Wilson disease is a rare monogenic, autosomal recessive disorder of copper metabolism, leading to progressive accumulation of copper in different organs, essentially in the liver, brain and cornea. We report a case of a 25 years old man, Caucasian, with “wing-beating tremor” in the right arm that started with two month in advance of hospital admission, than evolved to the left arm, a week before hospitalization. The slit-lamp examination showed the presence of Kayser-Fleischer rings in both eyes. The laboratory tests and brain MRI confirmed the diagnostic of Wilson’s disease.
