Effects of the Transcranial Direct Current Stimulation on Prevention of Cognitive Dysfunction in Elderly Patients Submitted to Cardiac Surgeries: Prospective, Randomized and Double-blind Study
In Brief
A clinical study evaluating tDCS for Postoperative Cognitive Dysfunction. Completed, enrolled 138 participants across 1 site.
Detailed Summary
Postoperative cognitive dysfunction (POCD) is a contrary event observed between 20 to 83%, especially on elderly and patients submitted to cardiac surgery. The prevention and rehabilitation on cases of POCD can improve the quality of life and decrease the mortality in surgical patients. The effect of the noninvasive cerebral stimulation, also known as transcranial Direct Current Stimulation (tDCS) has been studied to be used in the treatment of brain injuries and depression, and also in the cognitive rehabilitation. The hypothesis is that the use of the tDCS technique can decrease the occurrence of POCD and cognitively rehabilitate patients submitted to cardiac surgeries.
Study Details
Timeline
Interventions
Application of two daily sessions of cerebral stimulation starting from the first day after de surgery, for 4 consecutive days, with each session having 20 minutes, having an 8 hour minimum break between them. Will be applied a direct current stimulus of 2 milliampere (mA) (right anode/left cathode) in the prefrontal right region.
