What is transcranial tDCS?
Transcranial Direct Current Stimulation. Transcranial direct current stimulation (tDCS), is a non-invasive, painless brain stimulation treatment that uses direct electrical currents to stimulate specific parts of the brain. A constant, low intensity current is passed through two electrodes placed over the head which modulates neuronal activity.

Is deep brain stimulation effective in the treatment of Parkinson's disease?
Background: Progression of Parkinson's disease (PD) is characterised by motor deficits which eventually respond less to dopaminergic therapy and thus pose a therapeutic challenge. Deep brain stimulation has proven efficacy but carries risks and is not possible in all patients.
What are the side effects of tDCS?
The most common side effect of tDCS is a slight itching or tingling on the scalp. Several studies suggest it may be a valuable tool for the treatment of neuropsychiatric conditions such as depression, anxiety, Parkinson’s disease, and chronic pain.
Is TMS better than tDCS?
Moreover, TMS has better spatial and temporal resolution, TMS protocols are better established, but tDCS has the advantage to be easier to use in double-blind or sham-controlled studies and easier to apply concurrently with behavioural tasks.
Is tDCS FDA approved?
Several studies suggest it may be a valuable tool for the treatment of neuropsychiatric conditions such as depression, anxiety, Parkinson's disease, and chronic pain. Research has also demonstrated cognitive improvement in some patients undergoing tDCS. Currently, tDCS is not an FDA-approved treatment.
Is tDCS legal?
Currently, tDCS is not approved in the United States by the Food and Drug Administration (FDA) as a medical treatment for any indication.
Does tDCS increase dopamine?
The dopamine increases in the cathodal tDCS group were significantly greater than those in the sham and the anodal tDCS groups (p < 0.001 for both, post-hoc test).
Can tDCS cause brain damage?
Overall, little is known about either form of long-term risk, but there is currently no evidence that tDCS causes long-term damage when used within appropriate guidelines. It is currently unclear how cognitive functioning in non-target areas is effected by tDCS.
How long does tDCS effects last?
The authors demonstrated that 60 minutes of cathodal tDCS increased the threshold for localized seizure activity, and that this effect lasted for more than 2 hours.
Does tDCS work for everyone?
Considering these results, two conclusions become clear: (1) tDCS does not work for everyone, at the present it appears that only approximately 50% respond to stimulation, and (2) not all “responders” respond in the expected way (i.e., “classical” response).
Is tDCS ethical?
The early arrival of tDCS on the market for lifestyle uses and cognitive enhancement purposes lead to the voicing of some important ethical concerns, especially because, to date, there are no official guidelines or evaluation procedures to tackle these issues.
What lies ahead for FDA regulation of tDCS products?
For FDA to regulate a consumer tDCS product, the product must meet the legal definition of a device,3 which the Federal Food, Drug, and Cosmetic Act defines as an 'article' that, among other things, is intended 'for use… in the cure, mitigation, treatment, or prevention of disease' or 'to affect the structure or any ...
What stimulates frontal cortex?
Games: Word games, memory games, and puzzles are effective ways to strengthen your prefrontal cortex. Learning: Learning something new, like a language, instrument, or other skill, is even more effective than word games at enhancing your prefrontal cortex.
Can transcranial direct current stimulation on the dorsolateral prefrontal cortex improves balance and functional mobility in Parkinson's disease?
Our findings suggest that a-tDCS on the left DLPFC improves balance and functional mobility in comparison to sham-tDCS. Compensatory mechanisms that support motor function in individuals with PD may have been enhanced by a-tDCS on the DLPFC, leading to improved functional mobility and balance.
