This study is currently recruiting participants. (see Contacts and Locations)

ClinicalTrials.gov Identifier:
NCT01479855
First received: September 5, 2011
Last updated: November 26, 2013
Last verified: November 2013
  Purpose

The purpose of the study is to compare the concentrations of Vitamin B1 (thiamine), Vitamin B6 (pyridoxal-5-phosphate), folate, Vitamin B12 (cobalamin), Vitamin C (ascorbic acid), Vitamin A (retinol), Vitamin E (alfa-tocopherol), homocystein, uric acid, F2 8-α-isoprostane, 8-deoxyguanosine, retinoids, tau-protein and β-amyloid in spinal fluid, metabolomics, proteomics, m-RNA for DNA repair enzymes and DNA in patients who suffer from mild cognitive impairment (MCI) or mild dementia of Alzheimers type, with healthy controls.

A second aim is to explore the association between vitamin and nutrient reductions, if any, and cognitive function as well as vascular score and possible changes in the MRI.

Primary Outcome Measures:
  • Vitamin A [ Time Frame: Up to 4 weeks after inclusion ] [ Designated as safety issue: No ]
    The concentration of Vitamin A = Retinol (1.4-3.4 mmol/l) will be measured in serum from patients and healthy controls, and compared.

  • Vitamin B1 [ Time Frame: Up to 4 weeks after inclusion ] [ Designated as safety issue: No ]
    The concentration of Vitamin B1 = Thiamin diphosphate (55 - 126 nmol/l) will be measured in blood from patients and healthy controls, and compared.

  • Vitamin B6 [ Time Frame: Up to 4 weeks after inclusion ] [ Designated as safety issue: No ]
    The concentration of Vitamin B6 = Pyridoxal-5 phosphate will be measured in serum from patients and healthy controls and compared.

  • Vitamin B12 [ Time Frame: Up to 4 weeks after inclusion ] [ Designated as safety issue: No ]
    The concentration of Vitamin B12 = Cobalamin (140-600 pmol/l) will be measured in serum from patients and healthy controls, and compared.

  • Vitamin C [ Time Frame: Up to 4 weeks after inclusion ] [ Designated as safety issue: No ]
    The consentration of Vitamin C - Ascorbic acid (45-92 mmol/l) will be measured in serum of patients and healthy controls, and compared.

  • Vitamin E [ Time Frame: Up to 4 weeks after inclusion ] [ Designated as safety issue: No ]
    The concentration of Vitamin E = Alfa-tocopherol (16 - 36 mmol/l)will be measured in serum from patients and healthy controls, and compared.


Secondary Outcome Measures:
  • Cognitive function [ Time Frame: The cognitive testing will be performed between 0 to 4 weeks before the blood samples and spinal fluid is collected. ] [ Designated as safety issue: No ]
    The assessment of the cognitive function of patients as well as healthy controls will be done according to a comprehensive test battery used in Memory Clinics in Norway that concists of MMSE-NR, Clock-drawing-test and Ten-Word-Test (CERAD), TMTA and B, Abstract thinking, Boston Naming Test and FAS-COWA.
