Cognitive Aging: Cognitive function declines as we age. As our thinking and memory skills decline, the rate of functional dependence, mortality, and acute illness requiring hospitalization increases. A variety of methods have been proposed to counteract cognitive aging (e.g., cognitive training). Unfortunately, these techniques have limited degrees of success and transfer to everyday life. My work demonstrates that combining treatments like cognitive training with non-invasive brain stimulation (tDCS, TMS, tACS) facilitates neuroplastic response of brain tissue, improves cognitive abilities (specifically working memory, attention, and speed of processing), and leads to long-term improvement. In combination with modern multimodal neuroimaging and electrophysiology recording, this work not only identifies mechanisms underlying improvement, but also provides information important for further optimizing treatment effectiveness. Dr. Woods is PI of the largest NIH/NIA-funded Phase III tDCS trial, the ACT study. The ACT study investigates benefits of tDCS paired with cognitive training for cognitive and brain function and slowing onset of dementia in older adults.
Methodological Expertise: Non-invasive brain stimulation (transcranial direct current stimulation (tDCS), transcranial magnetic stimulation (TMS)); brain imaging (structural and functional magnetic resonance imaging); magnetic resonance spectroscopy (1H and 31P), human electrophysiology (event-related potentials).
