Transcranial direct stimulation is a practice that has been in existence for a while now. It can be carried out at special health units or even by individual therapies at the homes of patients. The whole process entails the stimulation of the brain neurons using some electric current that is passed from one point of the head to the other end. It uses some electrodes which are carefully placed on the head scalp to transmit the direct current through the brain area being stimulated. The tdcs process was initially developed to help patients with brain injuries like strokes.
The therapy is nowadays used in helping with various issues such as helping a patient with memory loss. It can also be used to help an individual increase their problem solving techniques. Additionally, it has been known to help increase a person attention span, help improve their mathematical solving techniques as well as improve their language ability. These different effects are achieved by placing the electrodes at different points of the head to affect different neurons in the brain.
The treatment simply works by allowing current to pass from one end on the head to the other. This is enabled by the use of a positively charged electrode and a negatively charged one. The electrodes are directed to regions where if the current flows from them and into the brain, it will reach the desired electrodes. The therapist should carefully place them at designated points. Failure to this, different results will be obtained rather than the expected.
Current used in this process is aimed at increasing or reducing the excitement that the neurons in the brain have. The level of excitement for these neurons affects different activities in the human brain such as attention span. By passing current from a positive cathode, the excitement is increased while passing the current from the cathode to the anode results in a reduction of the neurons excitement. The level of excitement in turn leads to different behaviors of the patient.
The process is quite easy and simple to set up provided that you have all the necessary equipment and skills needed to conduct it. First you need a power source that can deliver you direct constant current throughout the procedure. You also need an anode and cathode electrodes which are positively and negatively charged respectively. The electrodes should have pads that enable you to place them correctly and effectively on the scalp of a patient.
The scalp where the pads should be placed is then cleaned carefully to ensure that the pads have a strong connection with the head. This allows for the current to flow in and out effectively. Smaller pads will enable a more focused connection.
The process starts when the power device is turned on. The current is allowed to flow gradually from whichever electrode that the therapist desires. It can be increased or reduced gradually depending with the level of an effect desired.
The use of several electrodes also helps to increase the effectiveness of the results achieved. This is because there is more focus to the points desired. Results attained last more.
