The CBCL is a standardized form that parents fill out to describe their children's behavioral and emotional problems(e.g., anxiety, depression, social problems). The CBCL is also scored on (optional) competence scales for activities, social relations, school and total competence. The CBCL consists of 113 questions, scored on a three-point Likert scale (0=absent, 1= occurs sometimes, 2=occurs often). A higher score indicates a worse outcome.

VAS assessments are based on 10 NSRO (i.e., Alertness, Sleep Disorder, Motor Skills, Attention, Cognition, Communication, Behavior, Emotional/Social Functioning, Activities of Daily Living, and Participation). VAS is measured on a scale of 0-100; a score of 0 indicates a better outcome, and a score of 100 indicates a worse outcome.

The CGIC evaluates efficacy and quality of life. At enrollment the investigator will be asked to write a brief description of the patient's overall condition as a memory aid for assessment at each subsequent appointment. The CGIC comprises of the following question: "Since your child started treatment, please assess the status of your child's overall condition (comparing their condition now to their condition before treatment) using the scale below." The questionnaire is rated on a seven-point scale: "Very Much Improved" (1); "Much Improved" (2);Slightly Improved" (3); "No Change" (4); "Slightly Worse" (5); "Much Worse" (6); "Very Much Worse" (7). A score of 1 indicates a better outcome and a score of 7 indicates a worse outcome.

The CGICSD comprises the following question to be rated on a three-point scale for each seizure subtype: Since the patient started treatment, please assess the average duration of the patient's seizures (comparing their condition now to their condition before treatment) using the scale below. The scale markers are: 1=Average duration of seizures has decreased; 2=Average duration of seizures has stayed the same; 3=Average duration of seizures has increased. Higher scores indicate a worse outcome.

The PGIC evaluates efficacy and quality of life. At enrollment the investigator will be asked to write a brief description of the patient's overall condition as a memory aid for assessment at each subsequent appointment. The PGIC comprises of the following question: "Please assess the change in the patient's general functional abilities since enrolment." The questionnaire is rated on a seven-point scale: "Very Much Improved" (1); "Much Improved" (2);Slightly Improved" (3); "No Change" (4); "Slightly Worse" (5); "Much Worse" (6); "Very Much Worse" (7).
