Clinical Trial Summary

The aim of the current project is to validate whether chronic intake (24 weeks) roflumilast (PDE4 inhibitor) can improve cognition in patients with (amnestic) mild cognitive impairment (MCI) and in patients with mild dementia. The project will demonstrate whether episodic memory, but also attention, information processing or executive function improves with chronic administration of roflumilast in (a)MCI and mild dementia patients.
