Pantothenate kinase-associated neurodegeneration (PKAN) is an inborn error of CoA metabolism causing dystonia, parkinsonism, and brain iron accumulation. Lack of a good mammalian model has impeded studies of pathogenesis and development of rational therapeutics. We took a new approach to
We report on a patient with late-onset, pantothenate kinase-associated neurodegeneration (PKAN) who revealed two new heterozygous mutations at gene testing and showed asymmetric moderately reduced striatal dopamine transporter binding with single photon emission computed tomography, possibly due to
We studied a 68-year-old man who died after 13 years of progressive dementia, rigidity, bradykinesia, mild tremor, stooped posture, slow and shuffling gait, dystonia, blepharospasm, apraxia of eyelid opening, anarthria, aphonia, and incontinence. At autopsy, he had generalized brain atrophy with
A nine-month-old infant presented with fever and loss of milestones. Examination revealed intermittent rigidity and dystonic movements. Magnetic resonance imaging (MRI) shows decreased signal intensity in globus pallidus and substantia nigra, indicative of iron deposition, suggesting Hallervorden
The interrelationships were studied between catecholaminergic and cholinergic systems in 169 patients with extrapyramidal system diseases: 68 patients with torsion dystonia (58 with the rigid form and 10 with the hyperkinetic form), 10 with Hallervorden-Spatz disease, 61 with hepatolenticular
