Solution found in extreme dysfunction (6)
I believe the answer is:
remedy
'solution' is the definition.
(I've seen this before)
'in extreme dysfunction' is the wordplay.
'in' says the answer is hidden in the clue.
'REMEDY' is hidden within 'extreme dysfunction'.
'found' is the link.
(Other definitions for remedy that I've seen before include "Countermeasure" , "answer" , "Medicine or therapy that cures disease or relieves pain" , "Cure for illness" , "Medicine or therapy to cure" .)
