Abstract
Many inherited metabolic diseases or inborn errors of metabolism (IEM) cause movement disorders in children. This review focuses on chorea, dystonia, myoclonus, tremor, and parkinsonism. Broad neurometabolic categories commonly responsible for pediatric movement disorders include mitochondrial cytopathies, organic acidemias, mineral metabolism and transport disorders, neurotransmitter diseases, purine metabolism abnormalities, lipid storage conditions, and creatine metabolism dysfunction. Each movement disorder can be caused by many IEM and several of them can cause multiple movement abnormalities. Dietary modifications, medications, and increasingly specific therapy can improve outcomes in children with movement disorders caused by IEM. Recognition and characterization of secondary movement disorders in children facilitate their management and diagnosis, and possible treatment of an underlying IEM.

Abstract
Neurodegeneration with brain iron accumulation (NBIA) defines a heterogeneous group of progressive neurodegenerative disorders characterized by excessive iron accumulation in the brain, particularly affecting the basal ganglia. In the recent years considerable development in the field of neurodegenerative disorders has been observed. Novel genetic methods such as autozygosity mapping have recently identified several genetic causes of NBIA. Our knowledge about clinical spectrum has broadened and we are now more aware of an overlap between the different NBIA disorders as well as with other diseases. Neuropathologic point of view has also been changed. It has been postulated that pantothenate kinase-associated neurodegeneration (PKAN) is not synucleinopathy. However, exact pathologic mechanism of NBIA remains unknown. The situation implicates a development of new therapies, which still are symptomatic and often unsatisfactory. In the present review, some of the main clinical presentations, investigational findings and therapeutic results of the different NBIA disorders will be presented.

Abstract
Neurodegeneration with brain iron accumulation (NBIA) comprises a heterogeneous group of disorders characterized by the presence of radiologically discernible high brain iron, particularly within the basal ganglia. A number of childhood NBIA syndromes are described, of which two of the major subtypes are pantothenate kinase-associated neurodegeneration (PKAN) and PLA2G6-associated neurodegeneration (PLAN). PKAN and PLAN are autosomal recessive NBIA disorders due to mutations in PANK2 and PLA2G6, respectively. Presentation is usually in childhood, with features of neurological regression and motor dysfunction. In both PKAN and PLAN, a number of classical and atypical phenotypes are reported. In this chapter, we describe the clinical, radiological, and genetic features of these two disorders and also discuss the pathophysiological mechanisms postulated to play a role in disease pathogenesis.

Abstract
A 43-year-old male patient suddenly developed freezing of gait (FOG) when making a first step, turning, or passing through a narrow path. Dystonic plantar flexion of his left foot always accompanied with FOG. He could walk without FOG when stepping on visual cues. Brain magnetic resonance imaging study showed typical "eye of the tiger" sign in the globus pallidus. He had heterozygous mutations in the exons 3 and 4 in the PANK2 gene. His FOG dramatically responded to the anticholinergic treatment. We report the first instance of a patient with genetically confirmed pantothenate kinase associated neurodegeneration showing typical FOG that responded to anticholinergic treatment.

Abstract
Pantothenate kinase-associated neurodegeneration (PKAN) is a progressive neurodegenerative disorder with autosomal recessive inheritance. The major symptoms of PKAN include the onset before the age of 20 years, progressive pyramidal and extrapyramidal signs, retinitis pigmentosa, optic atrophy, dementia, and iron depositions in the globus pallidus. The authors present 3 patients with proven molecular diagnosis of PKAN, in whom 2 novel mutations of PANK2 gene have been identified.

Abstract
Inconsistent response in freezing of gait (FOG) with levodopa treatment or STN DBS makes the pathogenesis difficult to understand. We studied brain areas associated with the expression of STN DBS effect on parkinsonian motor deficits and FOG. Ten Parkinson's disease patients with typical FOG were included. One month before STN DBS, we performed [(18)F]-deoxyglucose PET scans and measured the UPDRS motor and modified FOG (mFOG) scores during levodopa off and on periods. At two months after STN DBS, same rating scores were measured. The percentage improvement of mFOG and UPDRS motor scores by STN DBS during levodopa off period was calculated. We searched for brain areas in which glucose metabolism correlated with the improvement of mFOG and UPDRS motor scores by DBS. During levodopa off period, STN DBS improved the UPDRS motor scores by 32.3% and the mFOG scores by 56.6%. There was no correlation between the improvements of both scores. The improvement of UPDRS motor score by DBS correlated with the metabolic activities of rostral supplementary motor area (Brodmann's area 8; BA8), anterior cingulate cortex (BA32), and prefrontal cortex (BA9). On the other hand, there was a positive correlation between the improvement of mFOG score by DBS and the metabolic activity of the parietal, occipital, and temporal sensory association cortices. In conclusion, dysfunction of different cerebral cortical areas limits the beneficial effects of DBS on parkinsonian motor deficits and FOG.

Abstract
Adult-onset focal dystonia was the presenting sign of pantothenate kinase-associated neurodegeneration (PKAN) in a patient with a novel homozygous missense mutation (C856T). His brother shared the same mutation and showed similar, albeit minor, motor signs, but a different behavioral profile. Both brothers had an atypical form of PKAN. The neuropsychological assessment showed that, despite a normal Mini-Mental State Examination, both patients presented a deficit of executive functions and of attention. The profile of cognitive impairment in these cases was typically that of a subcortical dementia. Both patients fulfilled Diagnostic and Statistical Manual for Mental Disorders criteria for obsessive-compulsive disorder; however, paranoia was associated with depression and aggressive behavior in Patient 1, whereas Patient 2 had hyperactivity, disinhibition, and euphoria. Our findings suggest that these two brothers had a different pattern of involvement of motor and nonmotor basal ganglia-thalamocortical circuits.

Abstract
BACKGROUND Hallervorden-Spatz syndrome is an autosomal recessive disorder characterized by dystonia, parkinsonism, and iron accumulation in the brain. Many patients with this disease have mutations in the gene encoding pantothenate kinase 2 (PANK2); these patients are said to have pantothenate kinase-associated neurodegeneration. In this study, we compared the clinical and radiographic features of patients with Hallervorden-Spatz syndrome with and without mutations in PANK2. METHODS One hundred twenty-three patients from 98 families with a diagnosis of Hallervorden-Spatz syndrome were classified on the basis of clinical assessment as having classic disease (characterized by early onset with rapid progression) or atypical disease (later onset with slow progression). Their genomic DNA was sequenced for PANK2 mutations. RESULTS All patients with classic Hallervorden-Spatz syndrome and one third of those with atypical disease had PANK2 mutations. Whereas almost all mutations in patients with atypical disease led to amino acid changes, those in patients with classic disease more often resulted in predicted protein truncation. Patients with atypical disease who had PANK2 mutations were more likely to have prominent speech-related and psychiatric symptoms than patients with classic disease or mutation-negative patients with atypical disease. In all patients with pantothenate kinase-associated neurodegeneration, whether classic or atypical, T2-weighted magnetic resonance imaging (MRI) of the brain showed a specific pattern of hyperintensity within the hypointense medial globus pallidus. This pattern was not seen in any patients without mutations. CONCLUSIONS PANK2 mutations are associated with all cases of classic Hallervorden-Spatz syndrome and one third of cases of atypical disease. A specific MRI pattern distinguishes patients with PANK2 mutations. Predicted levels of pantothenate kinase 2 protein correlate with the severity of disease.
