Objective: Patients with Wilson’s disease (WD) may develop a wide variety of neuropsychiatric symptoms, but there are few reports of autonomic dysfunction. Here, we described evidence of small fiber and/or autonomic dysfunction in 4 patients with WD and levodopa-responsive parkinsonism. Method: We reviewed the charts of 4 patients with WD who underwent evaluation for the presence of neuromuscular dysfunction and water-induced skin wrinkling test (SWT). Results: Two men and 2 women (33±3.5 years) with WD were evaluated. They all had parkinsonism at some point during their disease course. Parkinsonism on patient 4 almost completely subsided with treatment of WD. Two patients had significant sensory and 2 significant autonomic complaints, including syncopal spells. NCS/EMG was normal in all but SWT was abnormal in half of them (mean 4-digit wrinkling of 0.25 and 1). Discussion: A subset of patients with WD exhibit evidence of abnormal skin wrinkling test (small fiber neuropathy).

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.

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.

Background: Small fiber neuropathy (SFN) is a challenging subtype of peripheral neuropathies. Once the diagnosis has been established, there is an uncertainty how SFN may progress, whether larger fibers will become involved over time, whether quality of life may be compromised, or whether repeated diagnostic workup in patients with unknown underlying cause may increase the yield of treatable causes of SFN. Methods: We evaluated 16 patients with documented long-time course of idiopathic SFN. Results: Clinical and electrophysiological course remained stable in 75% of the patients, while 25% SFN-patients developed large fiber neuropathies. Conclusions: Our data suggest that SFN represents a benign disease course in the majority of patients without severely limiting the quality of life.

Abstract Background and aim Apathy is one of the neuropsychiatric symptoms of Wilson’s disease (WD) which typically affects the brain’s fronto-basal circuits. Lack of agreed diagnostic criteria and common use of self-description assessment tools lead to underestimation of this clinical phenomenon. The aim of this study was to investigate whether subjective and informant-based clinical features of apathy in patients with WD enable clinicians to make a valid diagnosis. Methods Multiple aspects of goal-oriented behavior were assessed in 30 patients with the neurological form of WD and 30 age-matched healthy participants using two questionnaires, the Lille Apathy Rating Scale (LARS) and the Dysexecutive Questionnaire (DEX). Both included a self-descriptive and a caregiver/proxy version. Cognitive functioning was estimated with the use of Addenbrooke’s Cognitive Examination-Revised. Results Patients obtained significantly worse scores on all clinical scales when more objective measures were considered. Features of apathy and executive dysfunction were revealed in patients’ caregiver versions of LARS and DEX, which may indicate poor self-awareness of patients with WD. Roughly 30% of participants were likely to present with clinically meaningful symptoms, independent of cognitive dysfunction. Conclusions Methods relying on self-description appear inferior to informant-based scales when diagnosing apathy. More objective criteria and measurement tools are needed to better understand this clinical syndrome.

Wilson’s disease is a hereditary disorder of copper metabolism which is characterized by neuropsychiatric and hepatic manifestations as well as appearance of Kayser-Fleischer ring. This is a retrospective review of the records of the patients of Wilson’s disease who attended Neuro-ophthalmic clinic for the identification of Kayser-Fleischer (K-F) ring from January2010 to June 2012. Detailed eye examination included visual acuity assessment, slit lamp biomicroscopy and intra-ocular pressure measurement. Data regarding clinical features, laboratory investigations and the status of K-F ring was recorded. Seven cases of Wilson’s disease with age range of 9-15 years were included in the study. Among them four (57.1%) had neuropsychiatric symptoms, two (28.5%) had hepatic disease and one (14.3%) was asymptomatic, diagnosed by positive family history and laboratory tests. Among four subjects having K-F ring, three (75%) subjects had neuropsychiatric symptoms and one subject had hepato-billiary disease. Besides K-F rings, other ophthalmic findings were sunflower cataract (14.3%) and vernal keratoconjuctivitis (14.3%). The identification of K-F ring is a simple and cost effective screening test for the diagnosis of Wilson’s disease. K-F is present in majority of the patients with neurological manifestations. DOI: http://dx.doi.org/10.3126/jcmc.v4i3.11934Journal of Chitwan Medical College 2014; 4(3): 17-20
