Niemann-Pick disease type C is an inborn error of metabolism that affects lipid degradation and storage. Hepatosplenomegaly and progressive neurological symptoms are the main clinical features. We present a case of an adult-onset type of Niemann-Pick disease in a 33-year-old woman who initially presented with dysarthria. At first, laboratory findings suggested Wilson's disease. Laparoscopy showed macroscopic signs of liver cirrhosis and histology did not confirm Wilson's disease. After bone marrow biopsy showed characteristic sea-blue histiocytes, Niemann-Pick disease was suspected and confirmed by filipin stain of cultured fibroblasts. Though rarely encountered, lipid storage disease should be suspected especially in younger patients with organomegaly and progressive signs of neurologic disease.

Thirty patients with Wilson's disease (WD) were observed at a movement disorder clinic between 1970 and 2000. Disease onset was at the mean age (SD) of 14.5 (+/-5.9) years. Presentation with hepatic disease occurred in 12 of 30 patients and with neurologic disease in 15. Three patients were asymptomatic at the time of diagnosis. The mean (SD) delay to diagnosis was 5.9 (+/-5.7) years. Five patients diagnosed in an advanced stage of disease died before initiating treatment. Eighteen patients were followed and treated with D-penicillamine alone or in combination with zinc sulphate. Treatment improved most of neurological symptoms. Dystonic postures, behavioural disturbances and dysarthria were the most resistant neurological signs. 'Pseudo-sclerotic' neurologic involvement predicted a good outcome, whereas hepatic onset and 'classic' neurologic involvement were associated with a poorer prognosis. Two of the 18 treated patients died of hepatic failure due to voluntary discontinuation of therapy. Both D-penicillamine and zinc sulphate were well tolerated. No teratogenic effect of D-penicillamine was observed throughout 5 pregnancies. Our results suggest that D-penicillamine or a combination of D-penicillamine and zinc sulphate is a safe and effective long-term treatment in patients with WD.

In this study we report an individual of Wilson's disease associated with olfactory paranoid syndrome and idiopathic thrombocytopenic purpura. The initial symptom of this female patient was olfactory paranoia at age 17. Although that psychiatric symptom was well controlled under pharmacological treatment for two years, she developed olfactory paranoia as well as sialorrhea, dysarthria and finger tremor at age 20. A year later rigidity was also present in the extremities. At age 23, idiopathic thrombocytopenic purpura was found based on hematological examinations. Because her extrapyramidal symptoms were progressive, she was referred to our department to evaluate her neurologic condition. She was diagnosed as having Wilson's disease based on (1) the presence of Kayser-Fleischer rings, (2) extrapyramidal signs, and (3) a decreased level of serum copper and ceruloplasmin. T2 and FLAIR images of brain MRI showed hyperintense lesions in the putamen, thalamus and pontine tegmentum. Diffusion-weighted images also showed hyperintense lesions in the thalamus and pontine tegmentum. The biopsy specimen of the liver revealed chronic hepatitis with copper accumulation. Since D-penicillamine treatment was initiated, she has shown no olfactory paranoia and exacerbation of ITP. Her gait disturbance has also improved. Olfactory paranoia and ITP are rare clinical complications of Wilson's disease. Further analysis may warrant consideration of the pathophysiological mechanism of the psychiatric, hematological and neuroradiological condition seen in Wilson's disease.

Wilson's disease is a genetic disorder of copper metabolism with a hepatic or neurologic presentation. A hepatic presentation is more common in young children. Neurologic Wilson's disease often manifests as a movement disorder with dystonia, tremor, and dysarthria. Psychiatric or behavioral symptoms can also be a presenting feature of Wilson's disease. We describe an atypical neurologic presentation in a prepubertal child with minimal hepatic involvement; in which transient hemiparesis and encephalopathy dominated her initial neurologic presentation. Brain magnetic resonance imaging revealed extensive cortical and subcortical signal change, in addition to the classical basal ganglia signal abnormality observed in Wilson's disease. She was treated with oral tetrathiomolybdate anticopper therapy, followed by zinc maintenance. Her clinical status and brain imaging improved considerably at 1 year after treatment initiation. Neurologic Wilson's disease may have diverse presentations, and should be considered in children who present with cortical features and signal change on magnetic resonance imaging.

Wilson's disease (WD) is a genetic neurodegenerative disorder; it exhibits wide heterogeneity in symptoms and usually presents with liver disease and/ or neuropsychiatric manifestations. The common neurological manifestations observed are dysarthria, gait disturbance, dystonia, rigidity, tremor, dysphagia and chorea. The frequent psychiatric manifestations reported are personality and mood changes, depression, phobias, cognitive impairment, psychosis, anxiety, compulsive and impulsive behavior. Isolated obsessive-compulsive disorder (OCD) is a rare presentation of WD. Reported herein is a case of a 17-year-old boy with isolated OCD. He presented to the psychiatrist with symptoms of contamination obsessions and washing compulsions, along with compulsion of repeated feet tapping and was treated with adequate doses of fluoxetine for 6 months but did not improve. Later on, he was diagnosed as a case of WD and showed improvement with chelating and behavior therapy. This implies the importance of the occurrence of isolated psychological symptoms in WD.

Wilson's disease (WD) is an autosomal recessive disorder characterized by the functional disruption of the copper-transporting protein adenosine triphosphatase 7B (ATP-ase 7B). The disease is caused by mutations in ATP7B gene. It seems that the type of mutation in ATP7B only to some degree determines phenotypic manifestation of WD. We examined two pairs of monozygotic twins discordant for WD phenotype. The first set of twins were ATP7B compound heterozygotes c.3207C>A (p.H1069Q)/c.1211_1212insA (p.N404Kfs). The index case developed severe liver failure followed by depressive symptoms, dysarthria, and tremor at the age of 36. Her sister remained presymptomatic at diagnosis at the age of 39. The second twins were ATP7B c.3207C.A (p.H1069Q) homozygotes. The index case presented with dysarthria and tremor at the age of 26. Her sister remained clinically presymptomatic at diagnosis at the age of 28. We concluded that the phenotypic characteristics of WD are possibly attributable to epigenetic/environmental factors.

The development of extrapyramidal syndrome characterised by rigidity, bradykinesia, dysphagia and dysarthria in a male individual with four distinct episodes of (mania like) behavioural disturbances with fairly good remission in a time frame of five years, in a male individual, was suspected to develop the neurological manifestations of Wilson's disease and was investigated. In the absence of Kayser-Fleischer ring by slit-lamp examination and with normal copper and ceruloplasmin serum levels, the diagnosis was possible because of the positive findings of the magnetic resonance imaging (MRI) studies and increased 24 hours urinary copper levels with the penicillamine challenge test. The findings and its implications are highlighted and discussed.

Despite a long history, Wilson's disease, an autosomal recessive disease caused by mutations in the ATP7B gene, remains a commonly misdiagnosed import disease. Mutations in ATP7B result in abnormal copper metabolism and subsequent toxic accumulation of copper. Clinical manifestations of neurologic Wilson's disease include variable combinations of dysarthria, dystonia, tremor, and choreoathetosis. Among neurodegenerative diseases, it is unusual in that misdiagnosis and delay in treatment are clinically relevant because treatments can prevent and cure Wilson's disease, if they are given appropriately. If left untreated, Wilson's disease progresses to hepatic failure or severe neurologic disability and death, while those adequately treated have normal life spans. This review focuses on the neurologic features of Wilson's disease, its diagnosis, and treatment options.

Three cirrhotic patients with chronic acquired hepatocerebral degeneration (CAHD) received neurologic, neuropsychologic and neuroimaging assessment before and after liver transplantation (LT). Before transplantation, neurologic dysfunction consisted in severe bradykinesia, dystonia, dyskinesia, ataxia and dysarthria. Cognitive impairment affected mainly attentional and executive domains. Brain MRI showed bilateral hyperintensities of the basal ganglia on T1-weighted images. After transplantation, motor manifestations promptly resolved. Cognitive testing showed a major improvement in two patients, whereas cognitive performances were slightly worsened in the third, reasonably due to the effects of a head injury before LT and a tacrolimus-related encephalopathy arising early after LT. MRI images 12 months later showed a slight reduction of the previously disclosed abnormalities in all three patients. None of them experienced recurrence of CAHD. Our observation reinforces the assumption that surgery is the best treatment option for CAHD and that severe neurological impairment in CAHD should not be considered a contraindication for LT.

Repeated episodes of liver failure or chronic liver cirrhosis may cause acquired (non-Wilsonian) hepatocerebral degeneration (AHCD). Patients with AHCD may show cognitive deficits, ataxia, dysarthria, movement disorders, including parkinsonism, and sometimes myelopathy. Various parenchymal and cholestatic hepatic disorders may result in AHCD. Most patients with AHCD have evidence of portosystemic shunting without necessarily having abnormal liver function. Recent evidence suggests manganese plays a crucial role in the pathogenesis of AHCD. Excess dietary manganese is rapidly cleared by the liver before reaching the systemic circulation. In patients with cirrhosis and portosystemic shunting, manganese bypasses the liver and accumulates in the internal pallidum, while serum manganese levels may be normal or increased. Magnetic resonance imaging abnormalities mainly consist of a signal hyperintensity on T1-weighted images in the internal pallidum. It may also be seen in the putamen, the caudate nucleus, the capsula interna, the mesencephalon, and the cerebellum, and is believed to reflect local manganese accumulation. No specific treatment of AHCD exists. Controlled studies are lacking, but case reports have stressed the usefulness of branched-chain amino acid therapy, trientine, and liver transplantation for the treatment of movement disorders. Levodopa may be efficacious in the treatment of AHCD parkinsonism.
