Zinc (Zn), copper (Cu) and magnesium (Mg) concentrations in cerebrospinal fluid (CSF) and serum were determined with atomic absorption spectrophotometry in 74 patients suffering from various neurological diseases, and in 28 healthy controls. Increased CSF zinc levels were found in the group of peripheral nervous system diseases (P less than 0.01) and in the(More)
Although trace elements have been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS) for a long time, new evidence has connected familial ALS with the metalloenzyme copper-zinc superoxide dismutase, thus reinforcing the study of their metabolism. This work presents the results of serum and cerebrospinal fluid levels of copper, zinc,(More)
BACKGROUND The cerebrospinal fluid (CSF) biomarkers amyloid β (Aβ)-42, total-tau (T-tau), and phosphorylated-tau (P-tau) demonstrate good diagnostic accuracy for Alzheimer's disease (AD). However, there are large variations in biomarker measurements between studies, and between and within laboratories. The Alzheimer's Association has initiated a global(More)
A 54-year-old man first was admitted with a right oculomotor nerve palsy that ameliorated spontaneously. Two months later, he was readmitted with right proptosis, ophthalmoplegia, and optic nerve involvement. MR showed an enlarged right cavernous sinus. There was dramatic improvement after high doses of steroids. MR findings 10 months later were normal.(More)
Cerebrospinal fluid (CSF) levels of tau protein and amyloid beta(1-42) peptide (Abeta42) have been suggested as possible diagnostic markers of Alzheimer's disease (AD). In order to evaluate their diagnostic potential in clinical practice, we measured tau and Abeta42 levels in the CSF of 49 AD patients, 15 patients with non-AD neurodegenerative dementias(More)
The aim was to quantify tau protein and-amyloid (A42) in the CSF of patients with sporadic Creutzfeldt-Jakob disease (CJD), Alzheimer's disease (AD), and controls. Double sandwich enzyme linked immunosorbent assays (ELISAs) were used for measurments. Tau was increased 58-fold in CJD and 3.5-fold in AD compared with controls, whereas A42 was decreased(More)
Axonal damage is now being recognized as a common finding in multiple sclerosis (MS) lesions and a cause of irreversible neurological damage. Attempts to identify markers of early axonal damage are of great significance. This prompted us to examine the microtubule-associated protein tau in the cerebrospinal fluid (CSF) of patients with MS vs. controls. Tau(More)
BACKGROUND AND PURPOSE The differential diagnosis between vascular dementia (VD) and Alzheimer's disease (AD) or mixed dementia (MD) is not always easy in clinical practice. The purpose of the present study was to evaluate the cerebrospinal fluid (CSF) biomarkers tau protein in its total (tau(T)) or hyperphosphorylated at threonin-181(tau(P-181)) form and(More)
The discovery of α-synuclein (α-syn) as a major component of Lewy bodies, neuropathological hallmark of Parkinson's disease (PD), dementia with Lewy bodies and of glial inclusions in multiple system atrophy initiated the investigation of α-syn as a biomarker in cerebrospinal fluid (CSF). Due to the involvement of the periphery in PD the quantification of(More)
The statistical tests analysis of variance, analysis of covariance, correlation coefficient, Kolmogorov-Smirnov test,t-test, and Tukey test were applied to copper, magnesium, managenese, and zinc content in serum (S) and in cerebrospinal fluid (CSF) of controls and of a sporadic form of Amyotrophic Lateral Sclerosis (ALS) disease. This is carried out in(More)
