If someone is mentally ill does that mean that when he complain about a crime it is always in his head?

No.

Mental illness is not synonymous with paranoia. Unless someone suffers from actual paranoid symptoms resulting from a personality disorder or delusions of persecution resulting from psychotic symptoms, they will rarely report crimes that did not occur.


Further, even those suffering from severe, debilitating paranoia can be victims of crimes. They, in fact, are a particularly vulnerable group.


Police officers and mental health providers should never assume that because a person is mentally ill, the crime was not committed.
