Amyotrophic lateral sclerosis (ALS) is a progressive nervous system disorder. It gradually destroys the nerves responsible for muscle movement. Over time, ALS leads to almost total paralysis of muscle movement, including breathing. Eventually, the disorder leads to respiratory failure.
The cause of ALS is unknown. Genes may play a role.
Factors that may increase your risk of getting ALS include:
Symptoms of ALS include:
You will be asked about your symptoms and medical history. A physical exam will be done. There are no tests that can diagnose ALS. Tests may be used to rule out other medical conditions.
Images may be taken of your bodily structures. This can be done with:
Your bodily fluids and tissues may be tested. This can be done with:
Your muscles and nerves may be evaluated. This can be done with
(EMG)/nerve conduction velocities (NCV).
Your cognitive skills may be assessed. This can be done with neuropsychological testing.
There is currently no cure for ALS.
Treatment may help to reduce or manage symptoms.
A combination of treatments may work best. This may include:
Treatment options include:
has been approved for ALS. The drug may slightly improve functioning, but it does not stop the disease from progressing.
You may be prescribed these medicines for symptoms:
Supportive care may be needed as ALS progresses, including:
There are no guidelines for preventing ALS because the cause is unknown.
