Forty-five patients with Wilson's disease (WD) were prospectively studied: 27 had neurological deficits, 12 hepatic signs, and 6 were asymptomatic. Kayser-Fleischer rings occurred in 23 of the neurological patients and in only 4 of the hepatic patients. Neurological features were extremely variable with respect to frequency and severity. Most frequent were dysdiadochokinesis (25 patients), dysarthria (23), bradykinesia (17), and posture tremor (14). Fifteen, mainly long-term treated patients, presented with rather discrete neurological abnormalities which predominantly consisted of dysarthria and various forms of tremor. Eight patients had a parkinsonian type of neurological WD associated with signs of an organic mood syndrome. Three patients were predominantly hyperkinetic, presenting with dystonic and choreatic movements. In 1 patient, ataxia was the predominant neurological feature. There was a clear-cut correlation between the severity of neurological impairment and the restriction in functional capacity. Nine patients were not able to engage in salaried employment or were retired. Psychiatric symptoms and behavioural disorders were common, varying from mild personality and psychological disturbances to severe psychiatric illness resembling psychotic disorders and major depressive syndromes. Significant mental deterioration was not found in the patients. Disturbances of mood were observed in 12 patients, all of whom had neurological abnormalities. There was a history of an attempted suicide in 7 patients, and a history of an organic delusional syndrome in 3.

Hallervorden-Spatz disease (HSD) is a rare autosomal-recessive hereditary disorder characterized by the early onset of progressive movement alterations, including dystonia, rigidity, choreoathetosis, and mental deterioration. HSD is also associated with a variety of psychiatric symptoms, primarily depression and mental deterioration. However, psychosis has rarely been reported as a major symptom of HSD. We report two siblings who presented psychiatric symptoms as major clinical presentations, accompanied by ataxic and spastic gait, dysarthria, and typical neuroimaging findings of HSD. A 14-year-old girl presented complex motor tics, stereotypic behavior and anxiety symptoms. Her older brother, a 16-year-old boy, presented prominent auditory hallucinations, persecutory delusions and social withdrawal symptoms. Psychiatric symptoms were improved after atypical antipsychotic treatment. HSD is a rare disease but should be carefully considered in the diagnosis of patients with both motor disorder and various psychiatric symptoms.

The Neuroaxonal Dystrophies (NADs) are a group of clinically and genetically heterogeneous neurodegenerative conditions. These disorders show the unique pathological feature of neuroaxonal dystrophy (NAD): axonal swelling (spheroids) localized throughout the central nervous and peripheral nervous systems. NADs are also morphologically characterized by iron accumulation in the basal ganglia; and are now included in the group of diseases called neurodegeneration with brain iron accumulation (NBIA). NADs comprise two main diseases: pantothenate-kinase associated neurodegeneration (PKAN) and infantile neuroaxonal dystrophy (INAD). PKAN in caused by mutation in the PANK-2 gene. In classic PKAN onset of disease is in the first decade and patients show dystonia, rigidity and dysarthria; course is progressive leading to loss of autonomous gait within 15 years. In atypical PKAN age at onset is later and progression slower. Psychiatric symptoms, obsessive-compulsive disorder, and tourettism may be prominent. In classic INAD patients present with psychomotor regression between 6 months-3 years, followed by neurological deterioration leading to tetraparesis, optic atrophy, and dementia. Atypical NAD refers to all patients who differ from the classical phenotype in term of age at onset and disease progression. Mutations in PLA2G6 gene are found both in classic and atypical INAD patients.
