The Mitochondrial Stress, Brain Imaging, and Epigenetics Study
In Brief
A clinical study evaluating Trier social stress test for Mitochondrial Diseases. Completed, enrolled 110 participants across 1 site.
Detailed 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.

Timeline
Interventions
The Trier social stress test (TSST) is a tool for investigating psychobiological stress responses in a laboratory setting. It is a laboratory procedure used to reliably induce stress in human research participants. The study is not examining or validating the test itself but rather using it as a tool to measure the response/focus of study.
