Thoughts regarding recent study of Montelukast and behavioral side effects

Hi all,

I am curious what other asthma providers think of the latest article regarding Montelukast being possibly linked to nightmares and aggression ( link to article here:  http://onlinelibrary.wiley.com/doi/10.1002/prp2.341/full ).  Has anyone seen this in their practice? 

Thanks for your thoughts and input!
