Synopsis

Keywords: Neurodegeneration, HypertensionPulsatility derived from the BOLD signal was used to assess the relationship of pulsatility damping in different sized cerebral arterial vessels across levels of blood pressure. Individuals with higher blood pressure exhibit reduced cerebrovascular compliance, and less damping of BOLD pulsatility among these individuals may be a potential indicator of cerebrovascular pathogenesis.
