Summary
Neuroimaging is crucial for identifying central nervous system (CNS) abnormalities in mitochondrial disorders (MCDs), as these findings can guide potentially treatable interventions and impact patient outcomes.
Area of Science:
- Neurology
- Radiology
- Medical Genetics
Background:
- Mitochondrial disorders (MCDs) frequently affect the central nervous system (CNS), second only to muscle involvement.
- Early detection of CNS abnormalities in MCDs is critical due to the potential for treatable conditions.
Purpose of the Study:
- To highlight the importance of neuroimaging in diagnosing and monitoring CNS involvement in MCDs.
- To outline the spectrum of CNS abnormalities detectable via imaging in MCD patients.
Main Methods:
- Review of clinically relevant imaging techniques including computed tomography (CT), magnetic resonance imaging (MRI), and MR-spectroscopy.
- Analysis of the diverse range of CNS abnormalities observed in MCDs.
Main Results:
- CNS abnormalities in MCDs encompass stroke-like lesions, necrosis, white matter changes, atrophy, calcifications, and vascular issues.
- Neuroimaging findings can manifest with or without clinical symptoms, necessitating routine assessment.
- Lesions exhibit variable dynamics, including progression, stability, or spontaneous/treatment-induced resolution.
Conclusions:
- Routine neuroimaging is essential for assessing CNS involvement in all MCD patients.
- Treatment targeting specific lesions, such as stroke-like lesions with L-arginine or steroids, can positively influence outcomes.
- Symptomatic management of CNS abnormalities improves the overall prognosis for MCD patients.
