Update: Jesse Jackson Jr. being treated for bi-polar disorder

So says the Mayo Clinic:

“Following extensive evaluation, Congressman Jesse Jackson, Jr. is undergoing treatment for Bipolar II depression at Mayo Clinic in Rochester, Minn. Congressman Jackson is responding well to the treatment and regaining his strength.

“Many Americans have bipolar disorder. Bipolar II disorder is a treatable condition that affects parts of the brain controlling emotion, thought and drive and is most likely caused by a complex set of genetic and environmental factors. Congressman Jackson underwent gastric bypass surgery in 2004. This type of surgery is increasingly common in the US and can change how the body absorbs food, liquids, vitamins, nutrients and medications.

“Congressman Jackson has asked Mayo Clinic to distribute this information on his behalf. He and his family remain grateful for support and prayers offered and received on his behalf.”

As we've reported, Jackson has been absent from Congress since early June and his whereabouts were a mystery for weeks, with many speculating he may have sought treatment for a drug or alcohol problem.  Jackson's camp recently alerted local officials that the Illinois Democrat still plans to seek reelection in November, despite his diagnosis.
