Functional ultrasound as a quantitative approach for measuring functional hyperemia in aging models.

ABSTRACT:

Backgrounds and objectives

Aging is associated with impaired cerebrovascular function, including reduced functional hyperemia (FH), which contributes to cognitive decline and dementia. Unraveling the mechanisms responsible for FH decline during aging is crucial for developing interventions to promote healthy brain aging and mitigate cognitive impairment. Currently, laser speckle contrast imaging (LSCI) serves as the standard method for assessing FH in mouse models of cognitive dysfunction and aging. However, as a terminal procedure, long-term monitoring of changes in FH using LSCI is not possible. Functional ultrasound imaging (fUS) has improved spatial and temporal resolution compared to LSCI and is a promising alternative, but surgical manipulation of the mouse model is necessary
