    ALS quick facts

    ALS, or amyotrophic lateral sclerosis, is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. There are few effective treatments for ALS and no cure.

    ALS, MS, and MD: How do they differ?

    Amyotrophic lateral sclerosis, multiple sclerosis, and muscular dystrophy can sometimes be confused as the characteristics and symptoms of these diseases can overlap. People living with ALS, MS, and MD often require the same kinds of wheelchairs and assistive devices. However, ALS, MS, and MD are separate and distinct diseases.

    Primary lateral sclerosis

    Primary Lateral Sclerosis (PLS) is a rare progressive neurodegenerative disease which is similar to ALS. However, ALS and PLS are not the same thing. Unlike ALS, PLS only affects the upper motor neurons. ALS affects both the upper and lower motor neurons.

    Kennedy’s disease

    Kennedy’s Disease is a rare genetic disease with symptoms that are similar to ALS. It is also called spinal and bulbar muscular atrophy.
    About ALS

    Bulbar ALS

    Bulbar ALS is a subtype of ALS that destroys motor neurons in the corticobulbar area of the brain and brainstem. This area controls muscles in the face, head, and neck including the jaw, lips, throat, and tongue.

    Non-motor aspects of ALS

    The non-motor aspects of ALS can fall into many categories. In this fact sheet are some of the more common non-motor symptoms, although people living with ALS may also experience other, less common ones.
