Transcranial direct-current stimulation (tDCS)
What is tDCS?
- One of the easiest ways to stimulate the brain noninvasively
- A safe method to improve motor and cognitive skills
- A good choice to combine with traditional therapeutic methods such as rehabilitation and pharmacological treatment
TDCS is a treatment for patients with psychiatric and neurological disorders in which the cerebral cortex is involved and whose functional recovery implicates neuroplastic processes.
- Head injuries
- Parkinson's disease
- Chronic neuropathic pain
- Dementia and mild cognitive impairment (MCI)
- Certain types of depression
- Tinnitus, …
TDCS involves electrical stimulation of the brain by applying a weak direct current to the patient's scalp (equivalent to a 9-volt battery) via sponge electrodes soaked in saline. The electric current passes through the skull to specific regions of the brain. The estimated duration is about 10 to 15 sessions performed on an outpatient basis. Each session lasts about 20 minutes.
