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)
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)
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)
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)
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 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 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)
Aim of the report was the study of the clinical features of neurosyphilis in the last 40 years (1965-2005). The investigation was based on the retrospective review of patients with neurosyphilis hospitalized in our hospital from 1965 to 2005 (period A: 1965-1984 and B: 1985-2005). Eighty one patients with neurosyphilis were studied. Typical forms represent(More)
The aim of the present study was to explore a possible interplay between cholinesterase inhibitors (ChEIs) and thyroid function tests (TFTs) in patients with Alzheimer's disease (AD). We reviewed thyroid function tests in 19 patients with AD before and after treatment (Rx) with ChEIs. Immunoradiometric assays were used for measuring serum thyrotropin, free(More)
IMPORTANCE Cerebral amyloid-β aggregation is an early pathological event in Alzheimer disease (AD), starting decades before dementia onset. Estimates of the prevalence of amyloid pathology in persons without dementia are needed to understand the development of AD and to design prevention studies. OBJECTIVE To use individual participant data meta-analysis(More)
