Amyotrophic Lateral Sclerosis (ALS) is a rapidly progressive and ultimately fatal neurodegenerative disorder marked by the selective loss of upper and lower motor neurons. Despite decades of research, conventional treatments remain limited to symptom management and modest extensions of survival, with no therapies capable of altering the disease's fundamental trajectory. Recent advances in molecular neurobiology have highlighted the critical role of chronic neuroinflammation, oxidative stress, mitochondrial failure, and neuroendocrine disruption as central, interlinked drivers of ALS pathogenesis. These discoveries demand a paradigm shift toward a system-based, personalized therapeutic model.

This paper introduces a comprehensive clinical strategy developed by Millennium Health Centers, built around a 28-point biomarker panel designed to detect subtle imbalances across inflammatory, oxidative, hormonal, and metabolic domains. By leveraging this diagnostic insight, the Millennium Protocol guides the application of precision nutraceuticals to downregulate pro-inflammatory cytokines and reactive oxygen species, alongside bioidentical hormone replenishment to restore neurosteroid balance and hypothalamic-pituitary axis integrity. Together, these interventions aim to reestablish systemic and neuronal homeostasis, mitigate ongoing neurodegeneration, and meaningfully enhance function and quality of life for individuals affected by ALS. This integrative approach represents a promising frontier in ALS care and warrants broader investigation through observational and interventional trials.
