Not so certain about that. I suffer from major depressive disorder and tweeted a while back speculating about this - I'd just come out of a depressive episode and noticed that my patterns of using social media were different than when I wasn't depressed - generally negative mood, lower interaction in general, mentions of drug abuse in chat, etc. I wondered if something monitoring my IM and Twitter could detect an incoming depressive episode before it fully hit, allowing me to 'prepare' a little more.
