Abstract

|
Transcranial direct current stimulation (tDCS) is non-invasive brain stimulation technique increasingly used for modulation of central nervous system excitability in humans. The use of non-invasive brain stimulation has significant advantages, such as not involving surgical procedures and having relatively mild adverse effects. In recent years there has been an exponential rise in the number of studies employing tDCS as a means of gaining an improvement on motor and cognitive function in patients with neurological diseases. In the present review, we will first introduce a brief background on the basic principles of tDCS. We also summarize recent studies with tDCS that aimed at enhancing behavioral outcome or disease-specific symptoms in patients suffering from stroke, movement disorders, Alzheimer disease, and epilepsy. Although outcomes of tDCS trials include some conflicting results, the evidence supports that tDCS might have a therapeutic value in different neurological conditions.
