Amanda Bynes

A judge has ruled to keep Amanda Bynes on psychiatric hold for another two weeks, TMZ.com reports.

Bynes was present for a hearing at the psychiatric hospital where she has been under a 5150 hold since Monday night. Even though Bynes had her lawyer present to argue her case, a judge granted doctors' request to keep her for two weeks so they can properly diagnose her, arguing that she could pose a danger to herself.

Report: Amanda Bynes' parents file for conservatorship in wake of 5150 psychiatric hold

On Monday, the fire department responded to the home in the actress' hometown of Thousand Oaks, Calif., and found Bynes standing in the driveway next to a fire. The sheriff's department arrived on scene and questioned the actress about her actions and intentions. Based on her answers, they decided she needed to be hospitalized on a 5150 hold, which allows for involuntary hospitalization for mental evaluation for up to 72 hours.

According to reports, Bynes may be suffering from a mental illness with schizophrenic tendencies, which is why her parents have reportedly filed for a conservatorship. The conservatorship would give them the authority to make decisions in the best interests of their daughter. Bynes' parents are expected in court Friday, but even if a judge declines the conservatorship, Bynes will still be under psychiatric hold for the remainder of the two weeks.
