NCT02940457

Brief Summary

This study investigates the beneficial effects of prefrontal brain stimulation (with transcranial direct current stimulation \[tDCS\]) during working memory training in seniors with mild cognitive impairments.The placebo-controlled double blinded study includes 50 elderly patients which will be randomized into verum or sham tDCS.

Outcome Measures

Primary Outcomes (2)

  • Brain activation measured with NIRS

    The Investigators are measuring brain activation during executive functions

  • Reaction times, errors and number of generated words in neuropsychological tasks

    The Investigators are measuring cognitive performance for different executive functions

    4 weeks

Secondary Outcomes (2)

  • T1 weighted magnetic resonance Imaging (MRI) of the brain

    4 weeks

  • Blood sampling

    4 weeks
