Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder characterized by the selective loss of motor neurons (MNs), leading to progressive muscle weakness, atrophy, and ultimately paralysis. This review provides a comprehensive overview of the molecular mechanisms underlying ALS pathogenesis, the genetic mutations associated with both familial and sporadic forms of the disease, and the latest therapeutic strategies aimed at mitigating disease progression. mutations in genes such as C9orf72, SOD1, TARDBP, and FUS have been implicated in ALS, with an intricate interplay of protein misfolding, oxidative stress, mitochondrial dysfunction, excitotoxicity, and neuroinflammation contributing to motor neuron degeneration. While current FDA-approved treatments such as Riluzole and Edaravone offer only modest benefits and do not significantly halt disease progression. Emerging therapies, including gene therapies (e.g., antisense oligonucleotides (ASOs) and CRISPR/Cas9, stem cell-based approaches, and neurotrophic factor supplementation, are demonstrating promising results in preclinical and early-phase clinical trials. novel approaches aim to target, modulate, and promote regeneration, renewed hope for future ALS treatments. However, several challenges remain, including effective delivery methods, safety concerns, and the inherent complexity of ALS pathology, ongoing research continues to explore these innovative interventions with the goal of improving clinical outcomes for patients. This review highlights the importance of personalized therapeutic approaches and underscores the necessity of continued innovation in ALS research, with the ultimate goal of developing disease-modifying therapies and, potentially, a cure for this fatal condition.
