Codes and Frequencies
For sample persons age 18 and older, EPILEPSYEV indicates if the sample persons have ever been told by a doctor or other health professional that they have a seizure disorder or epilepsy. Please see the Comparability and Survey Text Tabs for information on changes to the phrasing in this question over time.
Beginning in 2010, the field representative's manual defines seizures as "Some people may call it "convulsion," "fit," "falling out spell," "episode," "attack," "drop attack," "staring spell," or "out-of-touch". If the respondent mentions and counts "auras" as seizures accept the response. If a respondent indicates that he/she has had nothing more than an aura and is unsure about counting the aura(s), do NOT count auras as seizures."
Beginning in 2010, sample adults who acknowledged ever being told they had epilepsy were asked a series of follow-up questions. The variables related to these questions were:
- (EPILRXNOW) Now taking medication for epilepsy
- (EPILSEIZNOYR) Number of seizures in past 12 months
- (EPILMDYR) Saw neurologist or epilepsy specialist, past 12 months
- (EPILINTFERMO Epilepsy interfered with normal activities in past 30 days
