 (submitted: October 13, 2014)
  • Comparison of tDCS-induced changes on central cholinergic activity [ Time Frame: 1 week ]
    to investigate weather the anodal transcranial direct current stimulation affect central cholinergic activity (measured via a TMS protocol) in MCI patients compared to sham stimulation
  • Comparison of tDCS-induced changes in learning success [ Time Frame: 1 week ]
    tDCS-induced changes in learning success (performance in a motor learning paradigm in patients with MCI after tDCS vs. sham stimulation)

Brief Summary The aim of this study is to investigate whether the anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) in patients with mild cognitive impairment (MCI) leads to an increase in cortical plasticity (change in motor evoked potentials (MEP) in mV).
