What is tDCS?

Transcranial Direct Current Stimulation (tDCS) is an effective, drug-free treatment for Major Depressive Disorder. The therapy uses a mild electrical current to stimulate brain areas affected by depression. The therapy can be used to treat depressive symptoms as a stand-alone treatment or in combination with other treatment methods, such as medication, psychotherapy, or other neuromodulation therapies.

Sooma Depression Therapy is always prescribed by a healthcare professional, and is an easy-to-conduct tDCS treatment that only takes 30 minutes per day. After only one guided session, most patients are able to use it independently or even at home.



How does tDCS work?

Our brain function depends on electrical signalling. When people experience depression, this signalling becomes imbalanced in certain regions of the brain. These areas of the brain are found in the dorsolateral prefrontal cortex (DLPFC). For depressed patients, studies suggest that the left DLPFC experiences reduced activity, while the right DLPFC is overactive.

Sooma Depression Therapy specifically targets these areas to relieve depression. By administering a mild current through two electrodes inside of the head cap, the system stimulates activity near the left electrode while reducing the activity near the right electrode. This process can help to restore the balance between these two brain areas and can result in reduced depressive symptoms.

Are there any contraindications?

While Sooma Therapy is safe when used correctly, there are specific risk groups where caution should be used. If the patient has metal within the skull or an implanted life-supporting medical device in the body, the therapy should not be used. Further, if the skin under the electrodes is broken or diseased, the stimulation should not be applied.
