In the past, as hard as the researchers for mental imaging, chemical imbalance and Gene theory have tried.. they have failed. In fact, they have lied about the brain and caused a falsehood in science for self interest, political interests and greed.

There Are No "Chemical Imbalances"
APA lies to the American Public and puts the society in danger

There Are No "Chemical Imbalances"


"The hypothetical disturbances of neurochemical function that are said to underlie "mental illness" are just that: hypothetical. No experiment has ever shown that anyone has an "imbalance" of any neurotransmitters or any other brain chemicals. Nor could any conceivable experiment demonstrate the existence of a "chemical imbalance," simply because no one, least of all the biopsychiatrists, has the slightest idea what a proper and healthy chemical "balance" would look like."

"...the views and beliefs of biopsychiatry have nothing to do with the answers to scientific questions in any case: the hunt for biological "causes" of "mental illness" is an entirely fallacious enterprise in the first place; the non- existence of data to support its assertions is quite beside the point."

"The latest edition of one pharmacology text has this to say about the status of depression as a disease: "Despite extensive efforts, attempts to document the metabolic changes in human subjects predicted by these [biological] hypotheses have not, on balance, provided consistent or compelling corroboration." This is a long-winded way of admitting that not even a scrap of evidence supports the idea that depression results from a "chemical imbalance." Yet patients are told every day - by their doctors, by the media, and by drug company advertising - that it is a proven scientific fact that depression has a known biochemical origin. It follows directly that millions of Americans are being lied to by their doctors; and people surely can't give informed consent for drug treatment when what they're being "informed" by is a fraud.... To sum up: there is no evidence whatsoever to support the view that "mental illness" is biochemical in origin; in other words, things like "Unipolar Disorder" and "Attention Deficit Disorder" simply do not exist."

Can Brain Scans See Depression?

Pasted from < ;

Snips from the article:

After almost 30 years, researchers have not developed any standardized tool for diagnosing or treating psychiatric disorders based on imaging studies.


Psychiatrists still consider imaging technologies like M.R.I., for magnetic resonance imaging, and PET, for positron emission topography, to be crucial research tools. And the scanning technologies are invaluable as a way to detect physical problems like head trauma, seizure activity or tumors. Moreover, the experts point out, progress in psychiatry is by its nature painstakingly slow, and decades of groundwork typically precede any real advances.

Studies using brain scans to measure levels of brain activity often suffer from the same problem: what looks like a "hot spot" of activity change in one person's brain may be a normal change in someone else's.

"The differences observed are not in and of themselves outside the range of variation seen in the normal population," said Dr. Jeffrey Lieberman, chairman of the psychiatry department at Columbia University Medical Center and director of the New York State Psychiatric Institute.
To make matters even more complicated, many findings are disputed. In people with severe depression, for instance, researchers have found apparent shrinkage of a part of the temporal lobe called the hippocampus, which is critical for memory. But other investigators have not been able to replicate this finding, and people with injuries to the hippocampus typically suffer amnesia, not depression, psychiatrists say.
For problems like attention-deficit disorder and bipolar disorder, the experts say, psychiatrists have much less research on which to base their theories.
Most fundamentally, imaging research has not answered the underlying question that the technology itself has raised: which comes first, the disease or the apparent difference in brain structure or function that is being observed?


For a definitive answer, researchers would need to follow thousands of people from childhood through adulthood, taking brain scans regularly, and matching them with scans from peers who did not develop a disorder, experts say. Given the expense and difficulty, such a study may never be done, Dr. Hyman said.
