Primary outcomePrimary: Average TSST-induced Elevation in Cortisol — 37.44; 33.86; 42.83; 45.42 ng*min/mL
Summary
The MiSBIE study collects biological, behavioral, psychosocial, neuropsychological, and brain imaging data in participants with either: normal mitochondrial function, individuals with the m.3243A>G mitochondrial DNA (mtDNA) mutation, and individuals a single large-scale mtDNA deletion. These defects induce mitochondrial allostatic load (MAL). The 2-day protocol, plus home-based data collection, will provide a comprehensive assessment of the multi-systemic dysregulation associated with MAL or mitochondrial dysfunction, and the link to physical and mental health-related symptoms.
Aim 1: Determine the influence of MAL on systemic AL biomarkers.
Aim 2: Establish the influence of MAL on stress reactivity profiles.
Aim 3. Examine the association between MAL and psychological functioning.
