“…Educational level (years) did not differ between age groups. Overall, mean scores of neuropsychological tests (MMSE, PBAC and GDS) were within the expected range in the healthy Brazilian population [35], [37], [43]–[45]. However, OA had significantly lower MMSE and PIBAC scores than YA.…”

Age-Related Differences in Cortical Activity during a Visuo-Spatial Working Memory Task with Facial Stimuli

Emotion, importantly displayed by facial expressions, is one of the most significant memory modulators. The interaction between memory and the different emotional valences change across lifespan, while young adults (YA) are expected to better recall negative events (Negativity Bias Hypothesis), older adults (OA) tend to focus on positive stimuli (Positivity Effect Hypothesis). This research work aims at verifying whether cortical electrical activity of these two age groups would also be differently influenced by emotional valences in a visuo-spatial working memory task. 27 YA (13 males) and 25 OA (14 males), all healthy volunteers, underwent electroencephalographic recordings (21 scalp electrodes montage), while performing the Spatial Delayed Recognition Span Task using a touch screen with different stimuli categories: neutral, positive and negative faces and geometric pictures. YA obtained higher scores than OA, and showed higher activation of theta and alpha bands in the frontal and midline regions, besides a more evident right-hemispheric asymmetry on alpha band when compared to OA. For both age groups, performance in the task was worse for positive faces than to negative and to neutral faces. Facial stimuli induced a better performance and higher alpha activation on the pre-frontal region for YA, and on the midline, occipital and left temporal regions for OA when compared to geometric figures. The superior performance of YA was expected due to the natural cognitive deficits connected to ageing, as was a better performance with facial stimuli due to the evolutionary importance of faces. These results were related to cortical activity on areas of importance for action-planning, decision making and sustained attention. Taken together, they are in accordance with the Negativity Bias but do not support the Positivity Effect. The methodology used was able to identify age-related differences in cortical activity during emotional mnemonic processing and may be interesting to future investigations.

“…We used Brazilian versions of the Mini-Mental State Examination (MMSE; [35], [36]) and of the Philadelphia Brief Assessment of Cognition (PBAC; [37]). Additionally, the Geriatric Depression Scale (GDS; [38]) was used to assess depression or the potential for depression in older adults.…”

“…Subjects were randomly assigned to either a Neurofeedback training (NF) group ( n = 7), Sham Neurofeedback training (SNF) group ( n = 6) or No Neurofeedback training (NNF) group ( n = 4). All subjects were screened for cognitive and psychological conditions using the Philadelphia Brief Assessment of Cognition-PBAC (Pereira et al, 2012) with the screening criterion for normal range >49; the Beck Depression Inventory-BDI with the screening criterion for normal range <13; and the Beck Anxiety Inventory-BAI (Beck, 2001) with the screening criterion for normal range <10, which showed cognitive and emotional abilities were at normal levels (Table 1).…”

Cognitive aging has become a major concern because life expectancy has increased and elderly populations are socially and economically active. Neurofeedback is a technique of neuromodulation through operant conditioning paradigm that uses a computer interface to provide real-time information about brain activity to increase individual self-perception and assist in modulation. The sensorimotor rhythm (SMR) training protocol is known to enhance attention and has been applied to improve cognitive performance, primarily for attention and memory gains. The aim of this study is to test if the SMR protocol can improve working memory performance in an aging population and consequently favor cognitive reserve. Seventeen older adults (12 females) took part in a randomized placebo-controlled study. They completed a visual working memory test, Delayed Matching to Sample Task (DMTS), before and after the SMR neurofeedback protocol in order to compare their visual working memory performance. Moreover, a 19-channels EEG was collected while they perform the DMTS pre- and post-training. The experimental group showed an improvement in their working memory performance after the training with similar activation power, mainly in theta and beta frequency band at frontal and alpha at temporal regions. The sham group showed some variations in the score of working memory after the training, but were not statistically significant and their power spectrum demonstrate enhancement in alpha and beta band frontal and temporal. The group that did not receive neurofeedback training did not show a change in their working memory performance, neither in their EEG spectrum. The results suggest that neurofeedback can benefit brain reserve in an aging population because individuals enhanced their working memory performance after training and have their EEG activation changed according to expected in working memory tasks.

“…All subjects will be tested for depression using the 17-item Scale (Hamilton, 1960;Depression & Scale, 2004), since depression can be a confounding factor in the diagnosis of MCI. The Clinical Dementia Rating (CDR) (Morris, 1993), MiniMental State Examination-2: EV(MMSE) (Folstein et al, 1975) and the Philadelphia Brief Assessment of Cognition (PBAC) (Pereira et al, 2012) will also be assessed. To evaluate everyday memory and its possible improvement with tDCS the Rivermead Behavioral Memory Test (RBMT) (Wilson et al, 1989), California Verbal Learning Test (CVLT) (Delis et al, 2000), Rey Auditory-Verbal Learning Test (RAVLT) (Schmidt, 1996;Malloy-Diniz et al, 2007), and Digit Span (WAIS-IV) (Wechsler, 2008) will be employed.…”
