Objective. Amyotrophic lateral sclerosis/parkinsonism-dementia complex is classified as one of the tauopathies. Methods. The total tau, phosphorylated tau, and amyloid β42 levels were assayed in cerebrospinal fluid from patients with Kii amyotrophic lateral sclerosis/parkinsonism-dementia complex (n = 12), Alzheimer's disease (n = 9), Parkinson's disease (n = 9), amyotrophic lateral sclerosis (...
Studies have revealed that elevated homocysteine levels can cause damage to motor neurons through multiple neurotoxic mechanisms, thus leading to the pathogenesis of amyotrophic lateral sclerosis (ALS). One way by which homocysteine levels are increased in the body is the consequence of methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms. Therefore, to address this question, we studi...

Background: Evidence suggests that mitochondrial dysfunction and oxidative stress may be involved in the pathogenesis of Amyotrophic Lateral Sclerosis (ALS). Some studies show the presence of altered anti-oxidative defence enzyme activity in the blood of ALS patients. It has also been demonstrated that a superoxide-dismutase-1 (SOD1) enzyme fraction is located in the mitochondria. Objective: To...
The phosphorylated 43-kDa transactive response DNA-binding protein (TDP-43) was identified as a major disease in sporadic amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration. We present case with progressive muscle weakness who diagnosed ALS. On postmortem examination, TDP-43 immunoreactive neuronal cytoplasmic inclusions were noted motor cortex, hippocampus anterior horns...
Five to ten percent of amyotrophic lateral sclerosis (ALS) cases are associated with mutations of the superoxide dismutase-1 (SOD1) gene, and the 'D90A' mutation is associated with a unique phenotype and markedly slower disease progression (mean survival time 14 years). Relative sparing of inhibitory cortical neuronal circuits might be one mechanism contributing to the slower progression in pat...
A myotrophic lateral sclerosis (ALS) is an adultonset neurodegenerative disease characterized by progressive loss of motor neurons from the spinal cord, brainstem, and cerebral cortex that typically results in death 2 to 5 years following onset. Approximately 10% of patients with ALS have a family history, of which 15% to 20% are linked to mutations in the SOD1 gene; these patients most frequen...
There is increasing evidence that frontotemporal dementia and amyotrophic lateral sclerosis are part of a disease continuum. Recently, a hexanucleotide repeat expansion in C9orf72 was identified as a major cause of both sporadic and familial frontotemporal dementia and amyotrophic lateral sclerosis. The aim of this study was to investigate clinical and neuropathological characteristics of hexan...
BACKGROUND Accumulating evidence indicates that miRNAs play an important role in the development of amyotrophic lateral sclerosis (ALS). Most of previous studies on miRNA dysregulation in ALS focused on the alterative expression in ALS animal model or in limited samples from European patients with ALS. In the present study, the miRNA expression profiles were investigated in Chinese ALS patients...
Diagnosis, stratification and monitoring of disease progression in amyotrophic lateral sclerosis currently rely on clinical history and examination. The phenotypic heterogeneity of amyotrophic lateral sclerosis, including extramotor cognitive impairments is now well recognized. Candidate biomarkers have shown variable sensitivity and specificity, and studies have been mainly undertaken only cro...
