A tDCS procedure supporting mental health treatment
Transcranial direct current stimulation (tDCS) may reduce symptoms of depression and some other conditions by using a weak electrical current to support the activity and neuroplasticity of brain networks. tDCS is currently used in approximately 70 healthcare institutions in Estonia.
How does treatment work?
During a tDCS session, electrodes are placed on different areas of the patient's head. They stimulate brain regions involved in regulating mood, motivation, concentration and decision-making. Repeated sessions aim to support the brain's natural ability to adapt and help restore everyday functioning.
A session usually lasts about 30 minutes. The patient remains awake throughout; the procedure is painless and should not cause discomfort. Read more in the frequently asked questions .
The best results are achieved through a comprehensive treatment plan. tDCS can support medication, psychotherapy, physical activity and other recovery-supporting activities, but it does not replace the primary treatment prescribed by a healthcare professional.
When indicated, the service is funded by the Health Insurance Fund. At the patient's request, the service can also be provided without a referral. For more detailed information, please consult our nurse or doctor.
Frequently asked questions about tDCS
What is tDCS and what does a session involve?+
tDCS is a non-invasive procedure in which electrodes are placed on the scalp. A session usually lasts about 30 minutes and the patient remains awake. Occasionally, a patient may feel mild tingling under the electrodes.
How many sessions are needed before results can be noticed?+
tDCS effects develop over the course of treatment: a single session does not usually produce a large or lasting change. Some people may notice early changes about two weeks after starting treatment. The effect is individual, and a full course may require around 20–30 sessions or more. The treatment team evaluates the number of sessions and progress.
Is tDCS used for other mental health conditions?+
tDCS has also been studied in the context of ADHD, anxiety disorders, obsessive-compulsive disorder, schizophrenia and bipolar depression. For these conditions, scientific evidence and treatment outcomes are less consistent than for depression, so suitability is always assessed individually. In acute psychosis or severe delusions, tDCS is not a first-line intervention.
Does tDCS replace medication or psychotherapy?+
Generally, no. tDCS is a supportive treatment method. The best result is often achieved alongside the rest of a treatment plan, such as psychotherapy, medication, physical activity and activities that support daily functioning. Medication changes are only made under a physician's guidance.
Who is tDCS suitable for?+
Before treatment, symptoms, previous treatment, medications, skin condition and possible contraindications are assessed. For example, epilepsy, metal or an implant inside the skull, and skin damage in the electrode area require individual assessment. The decision to begin treatment is made with a healthcare professional.
