3D model of brain

​Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a progressive and fatal disease, attacking neurons that control voluntary movement. These neurons die over time. The result is the gradual loss of muscle movement, speech, swallowing, and eventually breathing. Unfortunately, people with ALS usually have a shortened lifespan and may die within a few years of diagnosis. ALS is most common in whites, males, and people over the age of 60. Over 17,000 people are estimated to be living with ALS in the United States.

    ALS Attacks Brain Cells Called NeuronsAmyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a progressive and fatal disease, attacking neurons that control voluntary movement. These neurons die over time. The result is the gradual loss of muscle movement, speech, swallowing, and eventually breathing.

    No One Knows Exactly What Causes ALSThe exact causes of ALS remain unknown. In 5%–10% of cases, ALS has a hereditary form, meaning it runs in families. The remaining 90% to 95% of cases have no clearly defined cause.

  • Make a Positive Difference: Join the ALS Registry and further ALS research

    Scientists Are Looking for the CauseThe National ALS Registry and the National ALS Biorepository are currently investigating the potential causes and risk factors of the disease.

    Getting Special Care Can HelpPeople with ALS usually have a shortened lifespan and may die within a few years of diagnosis. Multidisciplinary ALS clinics provide specialty care to people living with the disease. Attending ALS clinics may improve the quality and length of life of people living with ALS.

Prevention Tips

  • There is no definite method to prevent ALS.
  • However, people with ALS can participate in clinical trials, the National ALS Registry, and the National ALS Biorepository. This participation may help researchers learn about potential causes and risk factors of the disease.
  • Multidisciplinary ALS clinics provide specialty care to people living with the disease. Attending multidisciplinary ALS clinics may improve the quality and length of life of people living with ALS. You can learn more about ALS providers here.
