How The Tdcs Process Works And Its Many Merits To Patients

By Della Monroe


The transcranial direct stimulation therapy is a process that has been used to treat patients with brain injuries like stroke. This therapy is quite simple and can be carried out at a health unit or even the home of a patient. It involves the stimulation of brain neurons with some electric current which is passed through the head from one point to another point in the opposite direction. Tdcs is a critical process and requires professionalism in its undertaking. It should therefore be carried out by an expert with the experience on how the therapy works.

Transcranial direct current stimulation has been advanced to help with other various problems affecting patients. These include helping increase the attention span of an individual, their understanding of a language, problem solving skills and even reduce memory loss cases. A professional therapist understands which part of brain neurons need to be stimulated at a time in order to achieve each different behavior.

The direct electric current used can be passed through the neurons in two different ways. One is by passing it from a positively charged electrode known as the anode while the other is by passing the current from the negatively charged electrode called a cathode. Each mode of current stimulation achieves a different effect. In most cases, one effect is the opposite of the other if the current is passed in the opposite direction.

Electric current is used to cause an excitement of neurons in the brain. This is done by either increasing their excitement or reducing it. When the current flows from the positively charged electrode towards the negatively charged electrode, the resulting effect is an increase in the excitement of neurons. If the current flows from the negatively charged electrode towards the positive electrode, the resulting effect is a reduction in the excitement of neurons. The different resulting effects lead to different behaviors shown by the patient.

This procedure requires you to have a powered device and electrodes to pass the current through the head of a patient. The power source should be able to supply constant direct current during the exercise. Traditional methods have been using only two electrodes for the process. However, modern therapy has adopted the use of more than two electrodes to achieve higher levels of a certain effect.

The process starts with cleaning and preparing the skin on the scalp where the electrodes will be placed. This ensures that there will be a strong connection created between the skin and the electrodes. The electrodes are then attached carefully and current passed through.

Turn the power device on to generate and pass direct current through the head of the patient. The current is allowed to pass on gradually. It can be increased or decreased gradually as the therapist desires.

Modern technology has enabled the advancement of this therapy. In modern times, more electrodes that are smaller and more effective are used. The use of many smaller electrodes enables therapists to be able to target specific sectors of the brain and therefore achieve more effectiveness in results
