Study of Cerebrospinal Fluid Tissue Transglutaminase , T - TAU , Amyloid Β 42 in Alzheimer ’ s Disease
Biochemical markers for Alzheimer disease would be of great value, especially to help in early diagnosis of the disease. The current study has focused on three candidates that have been suggested to be indulged in the pathogenesis of Alzheimer’ disease (AD): Tissue transglutaminase (tTG) activity, β-amyloid42 (Aβ 42) and total T-tau (T-tau). The study included 15 patients with probable AD, 15 p...
متن کاملβ-Amyloid (1–42) Levels in Cerebrospinal Fluid and Cerebral Atrophy in Mild Cognitive Impairment and Alzheimer's Disease
BACKGROUND Recent studies consistently reported Alzheimer's disease (AD) and, to a lower extent, mild cognitive impairment (MCI) to be accompanied by reduced cerebrospinal fluid (CSF) levels of β-amyloid. However, how these changes are related to brain morphological alterations is so far only partly understood. METHODS CSF levels of β-amyloid (1-42) were examined with respect to cerebral atro...
متن کاملCerebrospinal fluid and -amyloid(1-42) in dementia disorders
The reliability of cerebrospinal fluid (CSF)and CSF-amyloid assays for diagnosis of Alzheimer’s disease and other dementing disorders such as frontotemporal dementia (FTD), dementia with Lewy bodies (DLB) and Creutzfeldt–Jakob disease (CJD) is reviewed. CSF assessment of the two proteins is useful in early diagnosis of AD and to differentiate it from FTD and DLB. Extremely high CSFlevels can di...
متن کاملPlasma beta carotene in Alzheimer's disease. Association with cerebrospinal fluid beta-amyloid 1-40, (Abeta40), beta-amyloid 1-42 (Abeta42) and total Tau.
We studied the plasma beta carotene concentrations in 40 Alzheimer's disease patients and the association with cerebrospinal fluid beta-amyloid 1-40, (Abeta40), cerebrospinal fluid beta-amyloid 1-42 (Abeta42) and cerebrospinal fluid total Tau. We found that patients with plasma beta carotene levels below the 25th percentile had 55% reduced ratios of Abeta40/Tau and 51% reduced ratios of Abeta 4...
متن کاملCerebrospinal Fluid Levels of Amyloid Beta 1-43 Mirror 1-42 in Relation to Imaging Biomarkers of Alzheimer’s Disease
Introduction: Amyloid beta 1-43 (Aβ43), with its additional C-terminal threonine residue, is hypothesized to play a role in early Alzheimer's disease pathology possibly different from that of amyloid beta 1-42 (Aβ42). Cerebrospinal fluid (CSF) Aβ43 has been suggested as a potential novel biomarker for predicting conversion from mild cognitive impairment (MCI) to dementia in Alzheimer's disease....
