NCT02185222

Brief Summary

As recommended allowance of oral vitamine D are unable to ensure the recommended serum concentration of vitamine D, the purpose of this study is to show that a dose of vitamin D3 higher than the recommended allowance may slow the cognitive decline of patients with a memory complaint.

Outcome Measures

Primary Outcomes (1)

  • Changes from baseline memory functions measured by the score of the total recall test from Free and Cued Selective Recall Reminding Test (Rappel Libre / Rappel Indicé 16 items : RL/RI 16) at one year and at two years

    The score of the total recall test from Free and Cued Selective Recall Reminding Test (RL/RI 16) is recommended by a European Task Force consensus.

    Baseline (at inclusion), one year and two years

Secondary Outcomes (19)

  • Changes from baseline global efficiency measured by the Mc Nair scale at one year and at two years

    Baseline (inclusion), one year and two years

  • Evolution of anaemia evaluated by red blood cells count

    Baseline (pre-inclusion), one year and two years

  • Evolution of plasma calcium and albumin concentration

    Baseline (pre-inclusion), 45 days, one year and two years

  • Evolution of urinary calcium and creatinine concentration

    45 days, one year and two years

  • All adverse events

    Up to two years

  • +14 more secondary outcomes
