Study summary

Transcranial Direct Current Stimulation (tDCS) is a non-invasive, painless brain stimulation treatment that uses low-intensity direct electrical currents to stimulate specific parts of the brain. Transcranial Direct Current Stimulation (tDCS) can both facilitate anodic stimulation and inhibit cathodic stimulation specific brain areas since many neurological and psychiatric disorders are connected to hypoactivity or hyperactivity in specific areas of the nervous system. This phenomenon is based on two processes: the reorganization of functional neural circuits and their reconstruction. In light of the studies mentioned above, it is presumed that Transcranial Direct Current Stimulation (tDCS) can be a valuable tool to facilitate the process of neuroplasticity in individuals with chronic neurological diseases and in patients with impaired consciousness following severe brain injury. A previous study demonstrated that a single session of transcranial direct current electrical stimulation could temporarily improve signs of consciousness in patients in a minimally conscious state (MCS)

Transcranial Direct Current Stimulation (tDCS) is a non-invasive, painless brain stimulation treatment that uses low-intensity direct electrical currents to stimulate specific parts of the brain. Transcranial Direct Current Stimulation (tDCS) can both facilitate anodic stimulation and inhibit cathodic stimulation specific brain areas since many neurological and psychiatric disorders are connected to hypoactivity or hyperactivity in specific areas of the nervous system. This phenomenon is based on two processes: the reorganization of functional neural circuits and their reconstruction. In light of the studies mentioned above, it is presumed that Transcranial Direct Current Stimulation can be a valuable tool to facilitate the process of neuroplasticity in individuals with chronic neurological diseases and in patients with impaired consciousness following severe brain injury. A previous study demonstrated that a single session of transcranial direct current electrical stimulation could temporarily improve signs of consciousness in patients in a minimally conscious state (MCS).

The application of weak currents can interact with neural processing, modify plasticity and entrain brain networks, and that this in turn can modify behaviour. The technique is now widely employed in basic and translational research, and increasingly is also used privately in sport, the military and recreation. The proposed capacity to augment recovery of brain function, by promoting learning and facilitating plasticity, has motivated a burgeoning number of clinical trials in a wide range of disorders of the nervous system. In this experimental study, cortical brain areas will be stimulated using transcranial direct current stimulation (tDCS) in patients with impaired consciousness following severe brain injury.

The main aim of this study is to determine whether the long-term effects of Transcranial Direct Current Stimulation (tDCS) stimulation can persist over time and whether this technique could be applied in clinical practice.
