Thanks a lot guys (Lauren, Valderson, William). Yes William I think your answer is correct. Anagarrett. The context is about a crazy dog who runs in everywhere and destroys everything without giving any attention to its owner in a crazy way. It is from a movie called " Togo".

no, it doesn't make sense. what was the context?

Hmm.... This doesn't make sense as written. Maybe these: Mental diversion? Mentally disturbed? Mentally divided? The first two don't really make that much sense, so I'd assume it is the third. Like: The dog is mentally divided (having a hard time choosing between) between chasing a squirrel or going to her owner for a treat.

Translading to my langue , it is correct!

Probably was ¨mentally deficient¨.
