OBJECTIVE Neurodegeneration with brain iron accumulation (NBIA) represents a group of inherited movement disorders characterized by iron accumulation in the basal ganglia. Recent advances have included the identification of new causative genes and highlighted the wide phenotypic variation between and within the specific NBIA subtypes. This study aimed to investigate the current status of NBIA i...
protein aggregation is thought to be the pathological driving force responsible for neurodegenerative disorders such as alzheimer’s, parkinson’s, huntington’s, frontotemporal dementia, dementia with lewy bodies and prion diseases, however, it is not yet clear whether, or to what extent, the misfolded proteins are the cause of the diseases rather than the consequences. the aggregated proteins th...
Abstract Background Cognitive decline occurs frequently in Parkinson’s disease (PD), which greatly decreases the quality of life patients. However, mechanisms remain to be investigated. Neuroinflammation mediated by overactivated microglia is a common pathological feature multiple neurological disorders, including PD. This study designed explore role cognitive deficits using rotenone-induced mo...
Aggregation of misfolded TAR DNA-binding protein 43 (TDP-43) is a striking hallmark of neurodegenerative processes that are observed in several neurological disorders, and in particular in most patients diagnosed with frontotemporal lobar degeneration (FTLD) or amyotrophic lateral sclerosis (ALS). A direct causal link with TDP-43 brain proteinopathy was provided by the identification of pathoge...
Traumatic brain injury (TBI) induces secondary injury mechanisms, including cell-cycle activation (CCA), which lead to neuronal cell death, microglial activation, and neurologic dysfunction. Here, we show progressive neurodegeneration associated with microglial activation after TBI induced by controlled cortical impact (CCI), and also show that delayed treatment with the selective cyclin-depend...
IMPORTANCE Converging evidence indicates that clusterin, a chaperone glycoprotein, influences Alzheimer disease neurodegeneration. However, the precise role of clusterin in Alzheimer disease pathogenesis is still not well understood. OBJECTIVE To elucidate the relationship between clusterin, amyloid-β (Aβ), phosphorylated tau (p-tau), and the rate of brain atrophy over time among nondemented ...
Pantothenate kinase-associated neurodegeneration (PKAN) is usually associated with dystonia, which is typically severe and progressive over time. Pallidal stimulation (GPi DBS) has been carried out in selected cases of PKAN with drug-resistant dystonia with variable results. We report a 30-month follow-up study of a 30-year-old woman with PKAN-related dystonia treated with GPi DBS. Postoperativ...
Hereditary spastic paraplegias and related genetically heterogeneous disorders may be difficult to distinguish clinically. The FA2H gene has been associated with autosomal recessive neurodegenerative phenotypes encompassing spastic paraplegia with or without dystonia, and demyelinating leukodystrophy. To date, few individuals with mutations in the FA2H gene have been described. We report a 5-ye...

The role of alpha-synuclein in pathogenesis of familial and idiopathic forms of Parkinson's disease, and other human disorders known as alpha-synucleinopathies, is well established. In contrast, the involvement of two other members of the synuclein family, beta-synuclein and gamma-synuclein, in the development and progression of neurodegeneration is poorly studied. However, there is a growing b...
