Seizure

Convulsión

Also: Ataque epiléptico (regional variant)

What it means

A seizure is the physical changes in behavior that occur during an episode of specific types of abnormal electrical activity in the brain. MedlinePlus describes seizures as symptoms of a brain problem that happen because of sudden, abnormal electrical activity in the brain. The term is often used interchangeably with "convulsion," but not all seizures cause convulsions, in which the body shakes rapidly and uncontrollably; some seizures have mild symptoms without shaking. Most seizures last from 30 seconds to 2 minutes and do not cause lasting harm. It is a medical emergency if a seizure lasts longer than 5 minutes or if a person has many seizures and does not wake up between them. Emergency signs need urgent care (call 911 in the U.S.).

Other Spanish termsWhere it is usedNote
ataqueGeneralMedlinePlus en español says the term "convulsión" is often used interchangeably with "ataque".
ataque epilépticoGeneralAppears in the alternative names MedlinePlus en español lists for its article on seizures, written as "Convulsiones - ataque epiléptico".

Convulsión is the word MedlinePlus en español uses for a seizure; its health topic opens Las convulsiones son síntomas de un problema cerebral. The noun is feminine: una convulsión, las convulsiones. English separates "seizure" from "convulsion" (MedlinePlus says not all seizures cause convulsions), but the Spanish page keeps convulsión for the event and describes the shaking with another word: No todas las convulsiones provocan estas sacudidas. The encyclopedia article adds that convulsión is often used interchangeably with ataque, and it uses the verb convulsionar.

Related words on the same pages are convulsiones focales, also called convulsiones parciales (focal or partial seizures), convulsiones generalizadas (generalized seizures), convulsiones febriles (febrile seizures) and epilepsia, which MedlinePlus en español uses for recurrent seizures due to a brain disorder. Staring spells are períodos de mirada fija. The emergency wording in the Spanish article is Llame al 911 o al número local de emergencia, and the Spanish topic page says it is a medical emergency if seizures last more than five minutes.

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.»
