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 (), Alzheimer’s disease (), Parkinson’s disease (), amyotrophic lateral sclerosis (), and controls () using specific enzyme-linked immunosorbent assay methods. Results. Total tau and phosphorylated tau did not increase and amyloid β42 was relatively reduced in Kii amyotrophic lateral sclerosis/parkinsonism-dementia complex. Relatively reduced amyloid β42 might discriminate Kii amyotrophic lateral sclerosis/parkinsonism-dementia complex from amyotrophic lateral sclerosis and Parkinson’s disease, and the ratios of phosphorylated-tau to amyloid β42 could discriminate Kii amyotrophic lateral sclerosis/parkinsonism-dementia complex from Alzheimer’s disease. Conclusions. Cerebrospinal fluid analysis may be useful to differentiate amyotrophic lateral sclerosis/parkinsonism-dementia complex from Alzheimer’s disease, amyotrophic lateral sclerosis, and Parkinson’s disease.

Abstract Background: To investigate the usefulness of cerebrospinal fluid (CSF) neuron-specific enolase (NSE) levels as a candidate biomarker of neurodegeneration in Alzheimer’s disease (AD), Parkinson’s disease (PD), PD with dementia (PDD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA).Methods: We performed a systematic search of PubMed, the Cochrane Library, SCOPUS, and Google Scholar to find studies that investigated the CSF levels of NSE in AD, PD, DLB, and/or MSA. For each disease, we pooled all available data and performed a meta-analysis, and meta-regression analyses of age and sex were conducted when significant in the main analysis.Results: Twenty studies were included (13 for AD, 8 for PD/PDD/DLB, and 4 for MSA). Significantly elevated CSF NSE levels were detected in AD (Hedges’ g = 0.822, 95% confidence interval [95%CI]: 0.332 to 1.311, p = 0.0010), but the data exhibited high heterogeneity (I2 = 88.43%, p<0.001). The meta-regression analysis of AD showed that age (p<0.001), but not sex, had a significant effect on NSE. A meta-analysis of all the pooled data for PD/PDD/DLB did not show any significant changes in the CSF NSE level, but a sub-group analysis of PDD/DLB revealed significantly elevated CSF NSE levels (Hedges’ g = 0.507, 95%CI: 0.020 to 0.993, p = 0.0412). No significant changes in CSF NSE levels were detected in MSA.Conclusions: This study provided evidence about the usefulness of CSF NSE levels as a biomarker in AD and PDD/DLB, and age was found to affect the CSF NSE levels of AD patients.
