Extreme obsession (5)

I believe the answer is:

mania

'extreme obsession' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for mania that I've seen before include "A (violent) mood disorder" , "Aberration" , "Obsessional enthusiasm" , "wildness" , "fixation" .)

I've seen this clue in the Newsday and the Newsday.com.
