Potential new approaches and recommendations for future research will be provided. All these topics will be discussed in the context of the literature of cognitive neuroscience of aging. ![]() Finally, similar results have been found in an extensive literature using resting state recordings which characterize the brain networks of patients with dementia in a non-task context. These studies assess sensory memory, short-term and long-term memory, indicating decreased activity and connectivity in AD patients but a dual pattern of increased/decreased functional connectivity at early stages such as mild cognitive impairment (MCI) or subjective cognitive decline (SCD). In the field of pathological aging, the literature has mainly focused on Alzheimer’s Disease (AD). In normal aging, we will go through the mechanisms of forgetting and the assessment of the default mode network organization. In this chapter, we will review MEG findings in normal and pathological aging. These characteristics make MEG unique for the study of the organization of the neurophysiological mechanisms supporting cognitive capabilities in the aging brain. Due to its excellent temporal resolution allows the evaluation of functional networks in the frequency domain. This is mainly because it is providing a new perspective in the study of this disease. The study of healthy and pathological aging with magnetoencephalography (MEG) has become more widespread in recent years. Significative differences were found in the healthy group between high and low cognitive reserve subgroups.Ĭonclusions: The Stroop Test, shows a high sensitivity in determining alterations in executive functions and the influence of cognitive reserve in that function. Results: The group of healthy subjects showed better performance on the test, than the pathologic group. Method: We used two samples, one consisting of 91 healthy subjects and a second sample of 32 subjects diagnosed with senile dementia of the Alzheimer type. ![]() Objectives: We intend to study the influence of cognitive reserve in executive functions in subjects with late onset Alzheimer´s disease, and in healthy subjects in a Portuguese sample. The Stroop Test has been used in the neuropsychological assessment of executive functions in aging-related disease, such as Alzheimer’s Disease. ![]() The Cognitive Reserve concept, generally understood as the acquired protective effect, is considered by many authors as an active mechanism that is based on the application of previously learned resources, due to a good education, profession and/or premorbid intelligence. ![]()
