Study summary

The investigators are developing a questionnaire that can quickly measure the impact that epilepsy has on a person's life. This questionnaire will be useful in following whether the impact of epilepsy increases, decreases or stays the same over time. The results also may point out areas that would benefit from discussion or attention in visits with your doctor.

Read the detailed description

The investigators have used a set of broad open-ended questions about the impact of epilepsy on a person's life to formulate a long list of questions to characterize the impact the seizures, medications, and comorbidities that you are having. In the future, this will be boiled down to a short list of questions.
