Children of Darkness (1983)

A significant number of American children and teenagers - from all social backgrounds - suffer from mental disorders, schizophrenia, autism and emotional problems, leading them to isolation from society while treating their issues in mental health facilities. But there's no end in sight for those young individuals when they face obstacles and mistreatment in inadequate places under the supervision of careless and inexperienced professionals. The documentary follows some of those public mental institutions and another private center dealing with troubled kids and reveals what's wrong with their procedures, and the irreparable harm they cause in those patients.

Unfortunately the movie Children of Darkness is not yet available on HBO Max.
