Amanda Bynes could leave her mental health facility in 60 days.

While doctors for the 27-year-old star - who is currently under involuntary psychiatric hold at UCLA - have recommended prolonged treatment, it is believed she will complete 60 days at her current facility before being released to the care of her mother, Lynn.

A source told TMZ: ''Doctors at the facility where Amanda has been held asked for a long-term hold, and they got it. Doctors then transferred control of the hold to Amanda's mother, who is currently the temporary conservator.

''It's unlikely Amanda will be held for a year. In fact, the plan is to keep her in a facility for 60 days to stabilise her and then transfer Amanda to her mom's home.''

It was claimed earlier this month that Amanda is doing much better and doctors believe she will learn to manage her mental illness.

A source said: ''Amanda has made significant improvements, she is doing better than she was.

''There are no drug problems involved, it's all mental. She has deep anger and PTSD (Post Traumatic Stress Disorder), which tripped a psychotic episode... She is very ill, but manageable. Amanda genuinely wants to get better and has wanted to get better for some time.''

The 'Easy A' star's PTSD allegedly stems from the pressure she has felt since carving out a successful career in Hollywood as a child star on Nickelodeon.

She was taken to the Hillman Psychiatric Facility in Ventura County, California, on July 22 after being arrested for starting a small fire outside a stranger's home in Los Angeles.
