What You Need to Know Before You Apply

What is the purpose of this trial?

The goal of this clinical trial is to better understand how day-to-day stress affects cardiovascular health and brain function in middle-aged adults. The main question is aims to answer is whether the link between daily stress and vascular dysfunction is a potential mechanism of increased risk for future cognitive decline. Participants will complete two 15-day "testing cycles" separated by \~6 months. During each cycle, participants will complete two daily assessments of stress and brain health using an online survey tool for 14-consecutive days. On the last day of each cycle, vascular function will be assessed during a laboratory visit.

Will I have to stop taking my current medications?

If you are currently using medications that affect heart function or any psychoactive drugs, you will need to stop taking them at least 8 weeks before joining the trial.

What Are the Treatments Tested in This Trial?

Interventions

• MitoTempol

Trial Overview The study tests the effects of daily stress on heart health and brain function using MitoTempol. It involves two 15-day testing cycles with daily online assessments and a final lab visit for vascular function checks.

How Is the Trial Designed?

Group I: MitoTempol Experimental Treatment 1 Intervention

Two intradermal microdialysis probes will be inserted into the dermal layer of the ventral forearm and perfused with either lactated Ringer's solution (control) or MitoTempol (0.5 mM) to scavenge mitochondrial-derived superoxide.
