ALS (Amyotrophic Lateral Sclerosis)
ELA (Esclerosis Lateral Amiotrófica)
What it means
Amyotrophic lateral sclerosis (ALS) is a nervous system disease that attacks nerve cells called neurons in the brain and spinal cord. These neurons transmit messages from the brain and spinal cord to the voluntary muscles, the ones a person can control, like those in the arms and legs. In ALS, motor nerve cells waste away or die and can no longer send messages to muscles, which eventually leads to muscle weakening, twitching, and an inability to move the arms, legs, and body. Early problems some people notice are trouble walking or running, trouble writing, and speech problems. ALS does not affect the senses (sight, smell, taste, hearing, touch). The condition continues to get worse, and there is no cure. ALS is also known as Lou Gehrig disease.
ALS (Amyotrophic Lateral Sclerosis) in Spanish
- Spanish term
- ELA (Esclerosis Lateral Amiotrófica)
- Gender and article
- feminine: la ELA (la esclerosis lateral amiotrófica)
- Pronunciation
- EH-lah (ehs-kleh-ROH-sees lah-teh-RAHL ah-myoh-TROH-fee-kah)
| Other Spanish terms | Where it is used | Note |
|---|---|---|
| enfermedad de Lou Gehrig | General | Name the MedlinePlus en español encyclopedia says the disease is also known by. |
| enfermedad de las motoneuronas | General | Listed by the MedlinePlus en español encyclopedia among its alternative names. |
The Spanish abbreviation is ELA, from esclerosis lateral amiotrófica; the English abbreviation is ALS, from amyotrophic lateral sclerosis. Both name the same disease, so "ALS" on an English record and "ELA" on a Spanish one match. ELA takes the feminine article: the MedlinePlus en español encyclopedia writes la ELA. The same encyclopedia says the disease is also known as la enfermedad de Lou Gehrig and lists enfermedad de las motoneuronas among its alternative names.
Words MedlinePlus en español uses with it: neuronas or células nerviosas (nerve cells), médula espinal (spinal cord), músculos voluntarios (voluntary muscles), debilidad muscular (muscle weakness), fasciculaciones (the muscle contractions English calls fasciculations) and espasticidad (muscle stiffness). For swallowing it uses both tragar and the more technical deglutir, and it calls a breathing machine un respirador.

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
