Area of Spain showing change of heart for mental condition (9)
I believe the answer is:
catatonia
'condition' is the definition.
(catatonia is a kind of condition)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for catatonia that I've seen before include "State of immobility and stupor" , "State of muscular rigidity and stupor" , "Unresponsiveness" , "Lifeless" , "unresponsive" .)
