Transcranial direct current stimulation (tDCS) is a non-invasive method of electrical brain stimulation. Specialized electrodes are attached to specific points on the scalp to stimulate brain activity. For example, to improve motor abilities, the researcher will place electrodes over parts of the brain that control motor function. Scientists at the Rotman Research Institute are investigating tDCS as a potential therapy for people who are impaired in a particular domain, such as language or memory. As well, tDCS is being used with stroke survivors to help them to regain lost abilities and recover faster. There is also promising research showing that tDCS could be used to treat symptoms of dementia. At Baycrest, we are currently running studies examining how tDCS could be used to improve memory, general cognition and ability to name objects in people living with Alzheimer’s disease or frontotemporal dementia.
