zonisamide and Abdominal Epilepsy

zonisamide has been researched along with Abdominal Epilepsy in 79 studies

Zonisamide: A benzisoxazole and sulfonamide derivative that acts as a CALCIUM CHANNEL blocker. It is used primarily as an adjunctive antiepileptic agent for the treatment of PARTIAL SEIZURES, with or without secondary generalization.

Analysis of Time to Drop Out Due to an Adverse Event (AE)

An AE is defined as any untoward medical occurrence in a subject and does not necessarily have a causal relationship with the medicinal product. Adverse events were identified by: any unfavorable or unintended sign, symptom or disease temporarily associated with the use of a medicinal product; any new disease or exacerbation of an existing disease; any deterioration in nonprotocol-required measurements of laboratory values or other clinical test; and recurrence of an intermittent medical condition not present at Baseline.

Analysis of Time to Drop Out Due to Lack of Efficacy

Lack of efficacy was evaluated by the subject and on the basis of whether zonisamide and carbamazepine gave the subject at least a 26-week seizure free rate. The subject could withdraw at any time due to lack of efficacy. (NCT00477295)

Change From Baseline in QOLIE-31-P Overall Score at Maintenance Period Visit 1

"The Quality of Life in Epilepsy - Problems(QOLIE-31-P) was completed by the patient and contained 30 items covering seven subscales(seizure worry, overall~Quality of Life (QOL),emotional well-being,energy-fatigue, cognition,medication effects and social function) and one item covering health status. It also included seven items addressing overall distress related to each subscale, an item addressing the relative importance of each subscale topic, and an item addressing perception of overall change in QOL at the end of the study. A high score reflects a good QOL. The following scale range is a sample of 1 of the 7 of the subscales:~10 (Best possible quality of life) - 0 (Worst possible quality of life);~Rand Corporation QOLIE-31 Scoring Manual was used. The QOLIE-31 overall score is calculated by summing the product of each scale score times its weight and summing overall all scales." (NCT00477295)

The Aldenkamp-Baker Neuropsychological Assessment Scale(ABNAS) is a subject based questionnaire to measure subjective perceived drug-related cognitive impairments. The ABNAS measured seven critical domains of cognition(tiredness/fatigue,hyperexcitability, slowing(mental and motor),memory impairment,attention disorders,impairment of motor coordination, and language disorders). The total score ranged from 0 to 72, with a higher score reflecting a high level of problems. (NCT00477295)

Change From Baseline in Bond and Lader VAS Mood Sub-Scores at Maintenance Period Visit 1

"The Bond-Lader Visual Analogue Scale (VAS) is made up of 16 pairs of alternative descriptors of mood and attention at either end of a 10 cm line.~Subjects were asked to rate their feelings at the time of assessment by indicating the point on the line which best represent their mood. Each item was scored by measuring the position relative to the left hand end of the line and levels of anxiety, sedation, and dysphoria were then calculated from the combined scores of selected items. The scores ranged from 0 to 100, with a high score reflecting a high level of anxiety, sedation or dysphoria." (NCT00477295)

The Short Form 36 Health and Well-Being Questionnaire (SF-36) is a 36-item generic health related QOL instrument covering the following domains: physical functioning, role-physical,bodily pain, general health, social functioning,role-emotional, mental health, and vitality. It yields a profile of eight scores, one for each domain, and physical and mental health summary measures. Each domain is described by a score ranging from 0 to 100, for a range of total possible scoes of 0-400 for physical and 0-400 for mental. An increase represents an improvement, whereas a decrease reflects a worsening. (NCT00477295)

Each domain has three levels, they are (1) no problems, (2) some problems, (3) extreme problems. The percentages shown are calculated from the number of subjects at that visit with non-missing data for that score. (NCT00477295)
