Age related differences in the recognition of facial expression: Evidence from EEG event-related brain oscillations

Are there consistent abnormalities in event‐related EEG oscillations in patients with Alzheimer’s disease compared to other diseases belonging to dementia?

“…Similarly, the peak frequency of theta responses was lower in older adults (mean = 4.1 Hz) compared to the young adults (mean = 5.2 Hz; van de Vijver et al, 2014). Findings with other measures of event-related thetas responses, such as phase-locking and phase synchronization, were less robust (Aktürk et al, 2020;Kolev et al, 2009;Müller et al, 2009). Concerning pathological brain aging, most studies showed a reduction of event-related theta power during memory tasks in ADMCI and ADD patients over CU participants.…”

“…Previous studies have shown mixed effects of aging on event‐related alpha responses. On the one hand, several studies reported greater event‐related alpha phase locking (Kolev et al., 2002; Yordanova et al., 1998) and power density (Aktürk et al., 2020; Babiloni et al., 2004; Karrasch et al., 2004; Schmiedt‐Fehr et al., 2016; Strunk et al., 2017) during auditory and visual tasks in older compared to younger CU adults. Furthermore, Dushanova and Christov (2014) showed that stimulus‐evoked alpha responses were greater in older compared to younger CU adults, while the opposite was true for event‐related alpha responses during cognitive demands.…”

Effect of Cognitive Control on Age-Related Positivity Effects in Attentional Processing – Evidence From an Event-Related Brain Potential Study

“…Older adults were more inclined to gatekeep negative emotions when their available cognitive resources were reduced, and the recruitment of cognitive control resources occurred in early visual processing. Cognitive neuroscientists over the past decade have documented compensatory cognitive scaffolding when frontal functional engagement increases ( Aktürk et al, 2020 ), accompanied by white matter integrity, cortical thickness, and dopaminergic activities. Moreover, even the functional engagement of the posterior regions, including the occipital area and hippocampus, decreases with aging ( Goh and Park, 2009 ).…”

“…Moreover, even the functional engagement of the posterior regions, including the occipital area and hippocampus, decreases with aging ( Goh and Park, 2009 ). Aktürk et al (2020) emphasized that older adults have higher theta phase locking values than their younger counterparts in the frontal regions. This posterior-anterior shift in the aging activation pattern is considered an important cognitive compensatory mechanism with aging ( Davis et al, 2008 ).…”
