While tDCS is still an experimental form of neurostimulation, it has proven to be valuable in understanding human brain networks by providing a tool capable of safely affecting neuronal activity.

“tDCS has been found to be a safe and well-tolerated investigational device as well as a treatment tool when used within the standard parameters,” said Dr. Wing Ting To, research scientist at Center for BrainHealth.

A more selective tool

tDCS should not be confused with electroconvulsive therapy (ECT), which uses a much greater electrical current than tDCS. Unlike ECT, which is known to affect the functioning of the entire brain, tDCS is far more selective in its effects. Moreover, the effect of a single session of tDCS is temporary and will disappear over time.

To achieve long-term effects, multiple sessions of tDCS need to be performed. The most common side effect of tDCS is a slight itching or tingling sensation directly beneath the tDCS electrodes.

Comprehensive brain care

By combining this targeted neurostimulation device with our research efforts in memory, traumatic brain injury, mild cognitive impairment and healthy populations, we hope to prime the brain and enhance plasticity to incrementally increase brain health and performance using tDCS.
