pantothenate kinase-associated neurodegeneration/dyskinesias

The clinical features of two children of a family with rapidly progressive extrapyramidal-pyramidal-dementia complex have been described. Inheritance seems most likely to be autosomal recessive. Magnetic resonance imaging results of brain were negative. Even so, the authors argued in favor of a

The arguments over the nomenclature of the syndrome are reviewed. Ethical considerations favour replacing the present eponyms with the title of panthothenate kinase-associated neurodegeneration (PKAN), now that more is known about the cause of the condition. The symptoms and signs of the syndrome

We report a 75-year-old man with parkinsonism who died suddenly. The patient was well until 64 years of the age when he had an onset of tremor in his left hand. He was treated with a medicine in another hospital, and his tremor subsided. Five years after the onset, he started to note difficulty in

Neurodegeneration with brain iron accumulation (NBIA) is etiologically, clinically, and by imaging a heterogeneous group including NBIA types 1 [pantothenate kinase-associated neurodegeneration (PKAN)] and 2 (PLA2G6-associated neurodegeneration), neuroferritinopathy, and aceruloplasminaemia. Data on

We report the case of a 56-years-old woman patient, born to unrelated parents, who since 26-years-old gradually developed bradykinesia, rigidity, tremor of both hands, and speech and gait difficulties. Her past history was unremarkable. There was no family history of neurologic disease. She was

Extrapyramidal movement disorders comprise hypokinetic-rigid and hyperkinetic or mixed forms, most of them originating from dysfunction of the basal ganglia (BG) and their information circuits that have been briefly reviewed in part 1 of the papers on neuropathology and pathogenesis of

BACKGROUND Neuroacanthocytosis (NA) syndromes are a group of rare diseases characterized by the presence of acanthocytes and neuronal multisystem pathology, including chorea-acanthocytosis (ChAc), McLeod syndrome (MLS), Huntington's disease-like 2 (HDL-2), and pantothenate kinase-associated

The term acanthocytosis is derived from the Greek for "thorn" and is used to describe a peculiar spiky appearance of erythrocytes. Acanthocytosis is found to be associated with at least three hereditary neurological disorders that are generally referred to as neuroacanthocytosis.
