Objective: Decline in cognitive functions, including impaired acquisition of novel skills, is a feature of older age that impacts activities of daily living, independence, and integration in modern societies. Methods: We tested whether the acquisition of a complex motor skill can be enhanced in old subjects by the application of transcranial direct current stimulation (tDCS) to the motor cortex. Results: The main finding was that old participants experienced substantial improvements when training was applied concurrent with tDCS, with effects lasting for at least 24 hours. Interpretation: These results suggest noninvasive brain stimulation as a promising and safe tool to potentially assist functional independence of aged individuals in daily life.
