Abstract (300 words maximum)
Theta/Beta ratio is an electroencephalograph (EEG) reading that has been shown to be a marker of cognitive capacity. A higher theta/beta ratio (TBR) is an indicator of increased central nervous system dysfunction in cortical areas. Blood pressure (BP) on the other hand has been significantly correlated with cognitive decline, specifically in the areas of memory and attention. However, there is less of a relationship between BP, speed of processing, and executive functioning. We intend to bridge this gap in knowledge by identifying the relationship between Theta/Beta ratio and blood pressure and what that may mean for cognitive decline in older individuals. We measured BP and TBR in a sample of 120 older community-dwelling adults, around half of whom were diagnosed with mild cognitive impairment (88 with complete data). Theta/Beta ratio was negatively correlated with blood pressure. This means that higher blood pressure may be an indicator of lower TBR.
