Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a progressive neurodegenerative disorder affecting nerve cells in the brain and spinal cord, leading to muscle paralysis and respiratory failure. The disease is rare, with approximately 33,000 cases in 2022 and a projected increase to over 36,000 by 2030.
Background
ALS primarily affects adults between 40 and 60 years of age and is slightly more common in men. It causes degeneration of both upper and lower motor neurons, resulting in muscle weakness, loss of coordination, and eventual paralysis. The exact cause remains unknown, although a small percentage of cases are inherited. There is currently no cure, but treatments like riluzole may modestly extend survival.

Key Findings
ALS causes progressive loss of motor neuron function, leading to muscle paralysis and respiratory failure.
Initial symptoms often include subtle muscle twitching and weakness, typically in limbs.
Diagnosis is challenging due to lack of definitive tests; it relies on clinical evaluation and exclusion of other conditions.
Riluzole is the only FDA-approved drug shown to modestly extend survival or delay need for ventilatory support.
Most patients survive 2 to 5 years after symptom onset; about 20% survive beyond 5 years.
Supportive care includes feeding tubes, mobility aids, and communication devices to manage symptoms.
Clinical Implications
Clinicians should maintain a high index of suspicion for ALS in middle-aged patients presenting with progressive muscle weakness and twitching. Early diagnosis is critical to initiate riluzole therapy and supportive interventions that may improve quality of life and survival. Multidisciplinary care is essential to address respiratory, nutritional, and communication challenges as the disease progresses.
Conclusion
ALS remains a devastating neurodegenerative disease with limited treatment options and poor prognosis. Continued research and supportive care strategies are vital to improve outcomes for affected patients.
