What is amyotrophic lateral sclerosis?

Amyotrophic lateral sclerosis, known by the acronym ALS, is a degenerative disease of the nervous system that gradually weakens muscles and affects movement and physical functions such as breathing and swallowing.

Symptoms

In ALS, nerve cells suffer progressive damage that reduces the functionality of the muscles they support. The main symptom is the progressive loss of movement, which leads to motor paralysis.

Causes

The causes of ALS are still unknown. It is estimated that at least 10% of cases have a genetic background.

Diagnosis

The diagnosis of amyotrophic lateral sclerosis involves a medical evaluation of symptoms and tests such as electromyography.

Prevention

There is no known way to prevent amyotrophic lateral sclerosis.

Treatment

Medication and therapy can slow the progression of ALS and reduce discomfort, but there is no cure.

Duration

ALS progresses over time. Paralysis can affect muscles essential for life, such as those responsible for breathing and swallowing. On average, ALS leads to death three to five years after diagnosis.

Is it contagious?

Amyotrophic lateral sclerosis is not contagious.

Can it be contracted more than once?

ALS is a degenerative disease with no cure. Once diagnosed, it remains with the person for life.
