NCT01479855

Brief Summary

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.

Outcome Measures

Primary Outcomes (6)

  • Vitamin A

    The concentration of Vitamin A = Retinol (1.4-3.4 mmol/l) will be measured in serum from patients and healthy controls, and compared.

    Up to 4 weeks after inclusion

  • Vitamin B1

    The concentration of Vitamin B1 = Thiamin diphosphate (55 - 126 nmol/l) will be measured in blood from patients and healthy controls, and compared.

    Up to 4 weeks after inclusion

  • Vitamin B6

    The concentration of Vitamin B6 = Pyridoxal-5 phosphate will be measured in serum from patients and healthy controls and compared.

    Up to 4 weeks after inclusion

  • Vitamin B12

    The concentration of Vitamin B12 = Cobalamin (140-600 pmol/l) will be measured in serum from patients and healthy controls, and compared.

    Up to 4 weeks after inclusion

  • Vitamin C

    The consentration of Vitamin C - Ascorbic acid (45-92 mmol/l) will be measured in serum of patients and healthy controls, and compared.

    Up to 4 weeks after inclusion

  • Vitamin E

    The concentration of Vitamin E = Alfa-tocopherol (16 - 36 mmol/l)will be measured in serum from patients and healthy controls, and compared.

    Up to 4 weeks after inclusion

Secondary Outcomes (1)

  • Cognitive function

    The cognitive testing will be performed between 0 to 4 weeks before the blood samples and spinal fluid is collected.
