The patient was experiencing certain obsessive thought loops leading to depression. The brain implant was targeting at disrupting the thought loops allowing for recovery.

I suspect it could quickly lead to addictive behaviors as patients give up on naturally improving their condition and learn to rely on pressing the button for more happy thoughts instead.
