Amyotrophic lateral sclerosis - An essential guide

Amyotrophic Lateral Sclerosis (ALS): A clear guide to Lou Gehrig's disease. Learn about ALS symptoms, life expectancy, diagnosis, and current treatment options.

20 January, 2026

Often known as Lou Gehrig's disease, Amyotrophic Lateral Sclerosis is a complex condition. Don't miss this vital overview of its causes, symptoms, and management, providing clarity on a widely misunderstood neurodegenerative disease.

What are the main causes of Amyotrophic Lateral Sclerosis?

  • For the vast majority of cases (sporadic ALS), the specific cause is unknown, though researchers are exploring potential genetic and environmental factors that may contribute.
  • About 5-10% of cases are inherited (familial ALS), caused by a mutation in one of several specific genes that can be passed down through families.
  • Research suggests that a complex interaction between genetic predisposition and environmental triggers, such as toxin exposure, may play a role in initiating the disease process.

Key symptoms of Amyotrophic Lateral Sclerosis to watch for

  • The early signs of ALS often include muscle twitching, cramping, or stiffness, along with weakness in a hand, arm, leg, or the muscles for speech.
  • As the disease progresses, individuals may experience difficulty walking, performing daily activities, and developing slurred speech (dysarthria) or trouble swallowing (dysphagia).
  • While motor function is severely impacted, it's important to note that the senses of sight, touch, hearing, taste, and smell typically remain intact.

How can you manage Amyotrophic Lateral Sclerosis effectively?

  • While there is no cure, an early and accurate ALS diagnosis is critical to begin managing symptoms and planning for future care with a multidisciplinary team.
  • The FDA has approved several medications for ALS treatment that may help to slow the progression of the disease and manage certain symptoms effectively.
  • Supportive therapies, including physical, occupational, and speech therapy, are essential for maintaining independence and quality of life for as long as possible.
