Summary

This research study explores the feasibility of pairing computer-based cognitive training (CBCT) with transcranial direct current stimulation (tDCS), a form of non-invasive brain stimulation, in order to enhance and preserve mental skills in older adults. The investigators aim to enhance participants ability to perform tasks of memory, attention, processing speed and other areas of cognition. Additionally, researchers are interested in the ability of the brain to adapt to change-neuroplasticity. Neuroplasticity is thought to impact how individuals respond to cognitive training and tDCS. In order to look at individual differences in neuroplasticity transcranial magnetic stimulation (TMS), a noninvasive brain stimulation technique, will be used. Individual responses to TMS can be used as a marker of neuroplastic changes in brain function, in order to reveal the relationship between brain plasticity and tDCS-induced changes in cognitive ability.

Interventions

DEVICE

Transcranial Direct Current Stimulation

tDCS is a neuromodulatory technique that delivers a small electric current (about the equivalent of a 9V battery) to the head. A fixed current between 1 and 2 mA is typically applied. tDCS works by applying a positive (anodal) or negative (cathodal) current via electrodes to an area, facilitating the depolarization or hyperpolarization of neurons, respectively.

BEHAVIORAL

Computer-based cognitive therapy (CBCT)

Repetitive, drill-like training usually presented in the form of a game that targets a specific cognitive construct.
