First-line treatments
Minimally invasive procedural intervention
Treatment may require specialized care, hospitalization, or long-term management under medical supervision.
Mitochondrial Supportive Diet
Specialized nutritional approach emphasizing ketone-producing foods and mitochondrial cofactors through diet. This includes supplementation with foods rich in B vitamins, CoQ10 precursors, and alpha-lipoic acid sources.
Multisystem Monitoring Protocol
Comprehensive regular monitoring of cardiac function, liver enzymes, neurological status, and respiratory capacity. Early detection of complications allows for timely intervention and quality of life optimization.
Additional treatment options
Mobility Preservation Therapy
Gentle range-of-motion exercises and positioning techniques to maintain joint flexibility and prevent contractures. Therapy focuses on functional independence within individual capabilities.
