INSTRUCTIONS TO BE READ TO PATIENTS:

Patients with epilepsy may at times experience a variety of psychiatric and cognitive symptoms. These symptoms can happen at any time, independent of the occurrence of seizures.

In some patients, however, these symptoms may only occur after a patient has had one or more seizures. We call these symptoms, postictal psychiatric and cognitive symptoms. These symptoms can occur anytime within three days after a seizure or cluster of seizures. This period of three days that follows a seizure is called the postictal period. In this study we are interested in investigating the occurrence of psychiatric and cognitive symptoms that you may have experienced during the postictal period in the course of the last three months.

In some patients, psychiatric and cognitive symptoms can occur as well in the absence of seizures. We call these, interictal symptoms. For each symptom that we are investigating, we are going to ask you if you have experienced it only after having seizures, or both, in the absence of seizures and after having seizures. In such cases, we want you to tell us if the severity of the symptom worsens significantly after having seizures. We also want you to estimate the average duration of each symptom.

CODING:

For each question, investigator needs to circle the corresponding number:

0 = never

1 = occasionally (after less than 50% of seizures)

2 = frequently (after more than 50% of seizures)

3 = all the time

PLEASE REMEMBER THAT THESE QUESTIONS PERTAIN TO SYMPTOMS OCCURRING UP TO THREE DAYS AFTER A SEIZURE THAT YOU MAY HAVE EXPERIENCED IN THE LAST THREE MONTHS.
