Jack's condition?

[hosoverpsychos.livejournal.com]

In Psychodrama at the beginning before the team leaves for LA Haley stops by to see Hotch and mentions that Jack had been at the hospital having tests. And we learn he has a condition that is treatable. Is it ever mentioned again and do we ever find out what the condition is/was? I haven't seen Psychodrama in a while and can't remember if it is mentioned at the end.
