NCT01046292

Brief Summary

The aim of this study is to evaluate the effects of Ginkgo Biloba Extract (GBE) in executive function-impaired Mild Cognitive Impairment (MCI) patients by assessing gait while walking alone as well as under differing dual-task conditions. The primary endpoint in the evaluation of GBE efficacy is gait speed. The secondary endpoint is cycle time variability under dual-task conditions.

Outcome Measures

Primary Outcomes (1)

  • gait speed

    baseline, 3, 6, 12 months

Secondary Outcomes (1)

  • cycle time variability

    baseline, 3, 6, 12 months

Study Arms (2)

Ginkgo biloba

EXPERIMENTAL
Drug: Ginkgo biloba

Placebo control

PLACEBO COMPARATOR
Drug: Ginkgo biloba

Interventions

The participants will be randomly allocated to either the intervention group or the placebo control group at a ratio of 1:1. After six months, GBE will be administered to all participants for another 6 months for free. The daily administered dose (taken with meals in the morning and evening) will consist of either twice-daily 1 capsule of Symfona® forte 120mg GBE or identically appearing placebo.

  • Participation in another clinical intervention study within the last 2 months
  • Use of walking aid
  • Normal walking speed is \< 100cm/s
