Juvenile Amyotrophic Lateral Sclerosis: A Case Report of a Rare and Aggressive Presentation in a 22-Year-Old Filipino...

Amyotrophic Lateral Sclerosis (ALS) is a rare neurodegenerative disorder primarily affecting adults, but juvenile-onset ALS is exceptionally rare. We report a rare case of a 22-year-old Filipino male patient who exhibited early-onset weakness, muscle atrophy, and tongue fasciculations, followed by rapidly progressive dysphagia and respiratory distress. Electromyography - Nerve Conduction Velocity (EMG-NCV) findings showed evidence for a chronic, active predominantly motor neuronal-axonal loss type of neuropathy involving the tongue and limb muscles bilaterally consistent with a motor neuron disease. The patient was treated with riluzole with no significant improvement in symptoms. Despite multidisciplinary interventions, the disease rapidly progressed, highlighting the challenges in managing juvenile ALS cases. This case report emphasizes the importance of considering ALS in the differential diagnosis of progressive motor dysfunction in younger patients and the complexities involved in their care.
