Clinical Trial Summary

The purpose of this study is to evaluate the effect of atorvastatin on brain vessel reactivity and with it on blood flow in people with mild cognitive impairment.

Description:

Participants are first being informed about potential benefits and risks of the study and are required to give written consent. After that participants will undergo detailed phone screen to determine eligibility for study entry. At week 0, participants who meet eligibility requirements will be prescribed atorvastatin (40 mg, once in the evening) in an open-label manner.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of MRI whole brain cerebrovascular reactivity (wbCVR)	MRI based CVR is a newer technique that measures dilatory function of the microvessels which have been shown to be superior to measurement of Cerebral blood flow (CBF) and have also been shown to be low in participants with MCI.	Baseline and 12 weeks
Secondary	Change in plasma exosomes	Endothelial-derived exosomes (EDE) reflect the neurochemistry of cerebrovascular endothelial cells, while neuronal-enriched extracellular vesicles (nEV) are associated with brain white matter hyperintensities.	Baseline and 12 weeks
Secondary	Change in cognitive function (global neurocognitive measure)	Assessed by Global neurocognitive measure.	Baseline and 12 weeks
Secondary	Change in cognitive function (domain-specific neurocognitive measure)	Assessed by Domain-specific neurocognitive measure.	Baseline and 12 weeks
