Roflumilast and Cognition (EEGrofl)

Effects of Roflumilast on Cognition in Healthy Adults: a Behaviour-EEG Study

The aim of the current project is to validate PDE4 inhibitors as a target for cognition enhancers (proof-of-concept) using a translational behaviour-EEG approach. The project will demonstrate whether memory, but also attention, information processing or executive function improves with the PDE4 inhibitor roflumilast in healthy humans.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of words remembered on Verbal learning task	30 monosyllable words will be displayed on a computer screen. Immediately after the presentation and after 45 minutes, subjects will be asked to report as much words as they remember. In addition, a recognition trial is conducted. Here, 30 words will be presented; 15 new words and 15 from the original list. Subjects have to indicate whether the word is old or new.	1hr after drug intake
