Various embodiments provide an implantable medical device comprising a detector, a neural stimulator, and a controller. The detector is configured to detect a pathological condition indicated for an acute neural stimulation therapy. The neural stimulator is capable of delivering a chronic neural stimulation therapy and the acute neural stimulation therapy. The controller is configured to control the neural stimulator to provide the chronic neural stimulation therapy, receive an indicator from the detector that the pathological condition is detected, and control the neural stimulator to integrate the acute neural stimulation therapy with the chronic neural stimulation therapy in response to the indicator.
