A week after calling police
with a health problem and being placed under a psychiatric hold
, Mischa Barton
is "making improvements" and will get back to work, her rep tells PEOPLE.
Specific details about the 23-year-old actress's condition were not available but Barton's rep says she is "still seeking treatment" and plans to return to work on the CW show The Beautiful Life
, which is scheduled to begin production July 31.
Friends have said the former O.C.
star is "dealing with personal issues
" and has been on "a destructive path" for a while.
According to a source, Barton has now left Cedars-Sinai Medical Center, where last week she was placed under a psychiatric evaluation, known as a 5150 hold
