Neurometabolic Profile of Individuals With Primary Mitochondrial Disease

Eligibility Criteria

• * Must be between 8 and 75 years, inclusive
• * Genetically confirmed primary mitochondrial disease
• * Receiving standard-of-care treatment including mitochondrial supplements that may include N-acetylcysteine (NAC), a precursor of glutathione
• * Must be between 8 and 75 years, inclusive
• * MRI contraindications
• * In the investigator's opinion, inability to fully comply with research procedures
• * Active self-reported alcohol and/or substance abuse, including tobacco-use
• * A pacemaker; any metal-based medical or non-medical devices/implants; any non-removable metal-based object (e.g., body piercings, jewelry, etc.) that cannot be cleared through radiologic evaluation
• * Any history of intraocular injury or fragment in or around the orbit that cannot be cleared through radiologic evaluation
• * Any history of bullet, shrapnel, or stabbing wounds that cannot be cleared through radiologic evaluation
• * Past or current employment involving (or exposure to) a metal grinder (e.g., at a construction worksite)
• * At the discretion of the principal investigator (PI), any medical condition that will interfere with or prevent the safe completion of the study
• * Any female participant with childbearing potential who is knowingly pregnant or suspects that she is pregnant will be removed from the study. (Although there are no known risks of MRI on pregnant females or fetuses, there is a possibility of yet undiscovered pregnancy-related risks. Since there is no direct benefit from participating in this protocol for pregnant females, they will be excluded to ensure their long-term safety and that of their unborn fetus.)
• * To note, for this protocol, participants are instructed to lie still in the MRI scanner; there is no contrast or sedation. Participants who do not possess the cognitive and / or physical abilities to perform these procedures will not be included.
