      This is a multi-centre, randomised, double blind, placebo controlled study on participants&#xD;

      Cognition and locomotion are two human abilities controlled by the brain. Their decline is&#xD;
      highly prevalent with aging, and is greater than the simple sum of their respective&#xD;
      prevalence, suggesting a complex age-related interplay between cognition and locomotion.&#xD;
&#xD;
      Recently, a systematic review and meta-analysis has provided evidence that poor gait&#xD;
      performance predicts dementia and, in particular, has demonstrated that &quot;motoric cognitive&#xD;
      risk&quot; (MCR) syndrome, which has been described in cognitively healthy individuals and&#xD;
      combines subjective cognitive complaint with objective slow gait speed, is a pre-dementia&#xD;
      syndrome.&#xD;
&#xD;
      MCR as a relatively new recognised clinical syndrome is with a high prevalence calculated&#xD;
      around 10% in world population aged 60 and above. MCR syndrome predicts mild and major&#xD;
      neurocognitive disorders. MCR syndrome does not rely on a complex and time-consuming&#xD;
      assessment, making it applicable to the aging population. Thus, MCR syndrome seems to be a&#xD;
      good syndrome to identify individuals at risk of mild and major neurocognitive disorders in&#xD;
      any type of healthcare setting.&#xD;
&#xD;
      Ginkgo Leaf Extract and Armillariella Mellea Powder Oral Solution has proven efficacy for&#xD;
      cognitive function deterioration in preliminary studies. The aim of this study is to evaluate&#xD;
      its efficacy and safety for MCR.&#xD;
