Overview
Brief Summary
The aim of this study is to investigate whether a combination of intensive training of visual-spatial abilities (LOCATO task) with anodal transcranial direct current stimulation (tDCS) leads to an improvement in learning and memory in patients with mild cognitive impairment (MCI) and to examine the underlying neuronal mechanism.

Outcomes
Primary Outcomes
Performance in LOCATO task (Visual-spatial learning and memory) after a combination of intensive visual-spatial training and tDCS
Time Frame: immediately after end of a 3-day period of training in tDCS condition vs sham condition
Investigation whether the combination of intensive visual-spatial training (LOCATO task) and tDCS leads to improvement of visual-spatial learning and memory measured by performance in LOCATO task after end of a 3 day period of training compared to sham stimulation.
Secondary Outcomes
- long term effects(after 1 month vs baseline)
- functional changes: Connectivity(end of 3-day cognitive training vs baseline)
- cortical excitability(at baseline)
- Quality of Life(after 1 month vs baseline)
- memory(immediately after end of 3-day of cognitive training, after 1 month vs. baseline)
- affective state(immediately after the end of 3-day cognitive training, after 1 month vs. baseline)
- genotyping of learning related polymorphisms(once)
