Aging and several neurological illnesses are associated with declining memory function. Simultaneously, cardiovascular disorders may disrupt the regulation of blood flow, which may have an impact on cognitive performance. The purpose of this study was to look into how aging affects blood flow regulation during memory tasks. We used highresolution functional near-infrared spectroscopy (fNIRS) to measure the pulse wave velocities, slopes and the shape of the blood pressure-related signals in several brain regions during memory tasks in both older and younger persons. This research involves a further examination of the pulse slopes by adding extra channels in LabChart to measure the first and second derivatives and identify the maximum and minimum points on event marker measurements. After extracting the data and calculating the average slopes for each channel, statistics showed that there was no obvious difference between the slopes of each task condition (Nback 1 and Nback 3) and each group (young adults and old adults). Future longitudinal studies should analyze more channels and consider N-back and rest conditions to understand cerebrovascular changes in aging and evaluate interventions aimed at preserving cognitive function, ultimately developing strategies to delay or prevent age-related cognitive decline.
