I am not an expert on Mental disorders, but know a little about the depressive and psychotic illnesses that are well established, documented and have fairly well identifiable symptoms and I agree that these illnesses should be well publicised.
However, i am concerned about what i would call "fringe illnesses", certain "dementias" ( Altzheimers excluded) ADHD, that other syndrome that was on a thread here yesterday (can't remember it;s name_. certain aspects of Autism and so on. Disorders which seem to be normal behaviour, but labelled a mental disorder to excuse the victim in some way. No blood or X-ray tests to identify the disorder.
It ia my opinion that many mental disorders e.g Autism and ADHD are OVERDIAGNOSED.
Yes, I agree with Dave....many are used as a "get out of jail card free" particularly depressive illnesses and for pleas of mental instability in the courts.
Where there is no diagnostic test there is scope for "faking."
