zonisamide and Cognition Disorders

zonisamide has been researched along with Cognition Disorders in 6 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.

Trial Outcomes

AB-Neurotoxicity Scale.

Total Scores AB-Neurotoxicity Scale Week 12. This scale provides subject ratings of anticonvulsant neurotoxic effects. Scores may range 0 to 72, with possibility of an additional 30 points being for complaints not listed in the list of complaints provides. Total scores, therefore, may be as high as 102, with higher scores indicating greater severity of problems. Actual mean scores are shown. Means for the analysis are least means squares values obtained from a two-way repeated measures mixed models analysis, with Week (time) as the the within subject factor and treatment as the between group factor. Baseline values were used as covariates. (NCT00862563)

The Primary Efficacy Measure is the Mean Number of Drinks Consumed Per Day Over the Period From Treatment Weeks 10 Through 12 When All Study Medications Should be at Their Maximum Steady Levels Based on Their Known Pharmacokinetic Properties.

Mean standard drinks consumed per day for each treatment week, weeks 10 thru 12. Actual mean values obtained are shown. Analyses are based on model generated least squares means for a two -way repeated measures mixed models analysis for data obtained for weeks 1 through 12, with baseline values used as covariates. Week (time) was used as the within subject factor and treatment group was the between group factor. (NCT00862563)
