Deranged (8)

I think it could be either:

demented

unhinged

'deranged' is the definition.
('unhinge' can be a synonym of 'derange')

This is the entire clue.

(Other definitions for unhinged that I've seen before include "Wild" , "Bats" , "Door may be" , "not flapping?" , "Mentally unbalanced like loose door?" .)

I've seen this clue in The Independent and The Mirror.
