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.

Condition or disease Intervention/treatment Phase
Mild Cognitive Impairment Device: Verum tDCS Device: Sham tDCS Not Applicable

Detailed Description:

In this project, we want to test whether the effectiveness of neuropsychological exercise therapy can be increased in elderly persons suspected of having an MCI by means of parallel tDCS treatment.

All test participants train over 6 sessions within 2 weeks two different working memory tasks with increasing difficulty. In the randomized, double-blind, prospective therapy study, participants are assigned to either a Verum-tDCS or a placebo-tDCS group. The Verum-tDCS group receives active stimulation in parallel to the exercise therapy, while the placebo group does not receive tDCS stimulation. To check the effects of the therapy, we measure performance and neuronal activation in different executive tasks using near-infrared spectroscopy (NIRS). Furthermore, we will check whether the training increases the volume of the grey matter (Draganski et al., 2004, Malchow et al., 2016) and the expression of BDNF can be increased (Schuch et al., 2015).

Arm Intervention/treatment
Experimental: Verum tDCS
prefrontal anodal stimulation
Device: Verum tDCS
Neuropsychological (working memory) training for 30 minutes, 6 sessions tDCS during training with 2 mA

Experimental: Sham tDCS
sham stimulation, same electrode positions
Device: Sham tDCS
Neuropsychological (working memory) training for 30 minutes, 6 sessions tDCS during training with 0 mA

Primary Outcome Measures :
  1. Brain activation measured with NIRS [ Time Frame: 4 weeks ]
    The Investigators are measuring brain activation during executive functions

  2. Reaction times, errors and number of generated words in neuropsychological tasks [ Time Frame: 4 weeks ]
    The Investigators are measuring cognitive performance for different executive functions

Secondary Outcome Measures :
  1. T1 weighted magnetic resonance Imaging (MRI) of the brain [ Time Frame: 4 weeks ]
    Structural changes in grey matter of the brain calculated by voxel based morphometry (VBM)

  2. Blood sampling [ Time Frame: 4 weeks ]
    Increased BDNF secretion in serum
