Now a patient undergoing psychiatric evaluation at L.A.'s Cedars-Sinai Medical Center, Mischa Barton has had her family worried sick for some
time, a source close to actress told RadarOnline.com exclusively.
"Her family had grown increasingly distressed over her erratic behavior over the past several weeks," the source said. "They are now in constant contact with the medical team at Cedars."
Mischa's health problems may not be her only issue facing the former O.C. star. There may only be a probation violation from her DUI plea in connection with why the police was called to Barton's home and had to take her to the hospital under CA Code 5150.
