Changes in event-related potentials during dual task walking in aging and Parkinson's disease

It has been theorized that walking in everyday life conditions requires higher cognitive processes that utilizes a complex neural network that incorporates cognitive and motor information (Woollacott and Shumway-Cook, 2002; Yogev-Seligmann et al., 2008). Most evidence supporting this notion relies on behavioral studies stemming from dual-task paradigms during walking to increase cognitive demands. These studies show that adding a simultaneous task to walking taxes executive function and attention and leads to changes in gait performance (Hausdorff et al., 2008; Yogev-Seligmann et al., 2008).
