Transcranial Direct Current Stimulation for Depression in Alzheimer's Disease Patient - Preliminary Research (ADAPT)

24. februar 2020 opdateret af: National Center of Neurology and Psychiatry, Japan

Ameliorating Depression in Alzheimer's Disease Patients by Transcranial Direct Current Stimulation (ADAPT) - Preliminary Research

This project will investigate the safety and efficacy of transcranial direct current stimulation (tDCS) in the treatment of depression among patients with Alzheimer's disease. The investigators aim to ameliorate depressive symptoms among patient with Alzheimer's disease, by anodal stimulation on left dorsolateral prefrontal cortex and cathodal suppression on right supraorbital area. Active stimulation will be compare to sham condition in 20 patients (10 in each groups).

Detaljeret beskrivelse

This project will investigate the safety and efficacy of transcranial direct current stimulation (tDCS) in the treatment of depression among patients with Alzheimer's disease. tDCS causes an excitatory effect on the anode side and suppressing effect on the cathode side through sculp with very week currents (2 mA in this project). The investigators aim to ameliorate depressive symptoms among patient with Alzheimer's disease, by anodal stimulation on left dorsolateral prefrontal cortex and cathodal suppression on right supraorbital area. Active stimulation will be compare to sham condition in 20 patients (10 in each groups) from outpatient clinic in National Center of Neurology and Psychiatry, Japan.
