Transcranial Direct Current Stimulation (tDCS) as a Cognitive Enhancer for Patients With Alzheimers Disease

The purpose of this study is to investigate transcranial direct current stimulation (tDCS) as a cognitive enhancer for patients with Alzheimer disease. Transcranial direct current stimulation (tDCS) is a neuromodulation technique, that are applied to the brain by using two electrodes. These electrodes are placed on the scalp. The current is low intensity, usually 1-2 milliampere. tDCS may affect cognitive functions by increasing cortical excitability. tDCS is regarded as a safe treatment approach. In the present study, participants will undergo six stimulations. The effect of all stimulations swill be measured with neuropsychological testing before the first (pre) and after the sixth tDCS stimulation (post).
