Influence of Triflusal on Cognitive Functions in Subjects Under Chronic Stress (Tricross-Basel)
Randomized Placebo Controlled Phase II Cross Over Study on the Influence of Triflusal on Cognitive Functions in Subjects Under Chronic Stress
Study Overview
Detailed Description
Randomised, placebo controlled, double blind, cross-over design
Primary study outcome is:
Performance in a verbal memory task.
Main secondary outcomes are: Performance in working memory and cognitive tasks and influence on mood, depression and anxiety and subjective memory impairment.
