No Tests to Diagnose Mental Illness

“There is no blood or other biological test to ascertain the presence of a mental illness, as there is for most bodily diseases. If such a test were developed, then the condition would cease to be a mental illness and would be classified, instead, as a symptom of a bodily disease.” – Professor of psychiatry emeritus Dr Thomas Szasz

DSM ICDClearly, the academics agree, there are no genetic tests, no brain scans, blood tests, chemical imbalance tests or X-rays that can scientifically or medically prove that any psychiatric disorder is a ‘medical’ condition.

If there were verifiable brain scans, or in fact any medical/scientific test that could show a physical/medical abnormality for any psychiatric disorder, the public would be getting such tests prior to being administered psychiatric treatments.

It is important to understand, medical diseases can be and are tested for and are universally recognised as such. Psychiatric ‘diseases’ however, are merely the opinions of the observer.


“There is no test for depression. Our understanding of the brain is simply not sophisticated enough. You diagnose from behaviour…We are more likely to treat depression because there are drugs available to treat it.”

Jim Bolton (Lecturer in Psychiatry, St. George’s Hospital, London 2001)

“Unlike the rest of medicine, which has developed diagnostic systems that build on an aetiological framework, psychiatric diagnostic manuals such as DSM-IV and ICD-10 have failed to connect diagnostic categories with any aetiological processes. Thus there are no physical tests referred to in either manual that can be used to help establish a diagnosis.”

Dr Sami Timimi, Child & Adolescent Psychiatrist

“The truth is that, unlike all other doctors, psychiatrists do not do physical tests to confirm their diagnoses. The reason is simple: it is not seen as necessary to prove that there is something wrong with the brains of patients diagnosed as schizophrenic, bipolar, depressed and so on. The organic hypothesis, however, remains unproven.”

Craig Newnes, The Guardian, 10 January 2002

“No biochemical, neurological, or genetic markers have been found for Attention Deficit Disorder, Oppositional Defiant Disorder, Depression, Schizophrenia, anxiety, compulsive alcohol and drug abuse, overeating, gambling or any other so-called mental illness, disease, or disorder.”

“There’s no biological imbalance. When people come to me and they say, ‘I have a biochemical imbalance,’ I say, ‘Show me your lab tests.’ There are no lab tests. So what’s the biochemical imbalance?”

Dr. Ron Leifer, Psychiatrist

“All psychiatrists have in common that when they are caught on camera or on microphone, they cower and admit that there are no such things as chemical imbalances/diseases, or examinations or tests for them. What they do in practice, lying in every instance, abrogating [revoking] the informed consent right of every patient and poisoning them in the name of ‘treatment’ is nothing short of criminal.”
