According to pharmaceutical drug-based psychiatry, depression is caused by a chemical imbalance in the brain. In spite of decades of research, this has never been proven. Now though, we’re seeing claims from medical science that PET scans prove there is a physical basis for depression. Are those claims meaningful—or merely flummery designed to give an impression with no bearing on reality?
John Mann, MD, head of the neuroscience department of the New York State Psychiatric Institute who did research on PET (positron emission tomography) scans in depression studies stated:
For years people have said that depression or mood disorders are a chemical imbalance in the brain. Now we have a large imaging center here on the medical campus and we’re actually able to image brain neurotransmitter systems in patients. Now we’ve shown unequivocal evidence of neurotransmitter abnormalities in bipolar disorder and in major depression…
Obviously, Mann believes—or wants us to believe—that there has never really been any doubt about depression, along with other so-called brain diseases, being caused by chemical imbalances. He states that PET scans prove, unequivocally, that people with bipolar disorder and major depression have abnormal brains.
So what’s his proof? It’s in this PET scan image from the Mayo Clinic:
The apparent differences between the brains of a depressed person, as shown on the left, and a “normal” person, as shown on the right, are impressive. The “normal” person’s brain appears to be far more active.
That seems quite convincing. Since the brain’s activity level is significantly different, it looks like there must be some underlying difference in the brains, something like a chemical imbalance. Let’s examine that idea more closely.
What happens while sleeping? PET scans have been used to study that question, and they demonstrate that different parts of the brain become more and less active during different stages of sleep and in wakefulness. Regional blood flow, indicative of level of brain activity, varies with the differing states. It’s certainly not true that any stage of sleep or wakefulness is superior to another, nor is it true that these changes are any indication of pathology.
Post traumatic stress disorder (PTSD) has also been studied with PET scans. The following video graphically shows the results of a PET scan during PTSD and after it’s alleviated by neuro-feedback. (The PET scan image is displayed from 1 minute into the video.)
Why would psychiatry scientists presume that changes in brain activity constitute proof of brain disease?
There simply is no logic behind the claim that PET scans prove that depression is the result of a brain chemical imbalance. All they’ve shown is that depressed people’s brains are less active. In no sense have they shown that depression is caused by lower brain activity. It’s every bit as plausible—and by Occam’s Razor, a better assumption—that lower brain activity is caused by emotion of depression, not the reverse. Neither have they demonstrated that increased or decreased brain activity is inherently beneficial or harmful.
None of this is particularly surprising. Psychiatry has defined itself according to a paradigm saying that mental illness is caused by physical disease. They have almost completely left behind any interest in life stresses that are involved with mental discomfort. By doing so:
Is it any wonder that the so-called scientists behind these treatments are so blind that they are unable to see the absurdity of the claim that a change in brain activity proves that there is a chemical imbalance?
The psychiatric profession, as a whole, has gone down a very dark tunnel and has left itself no room to turn around from a dark ending. They have nothing left but their faked evidence based medicine—which has become a rotting cesspool on which they base their sick occupation. The entire structure of the modern psychiatric profession’s focus on Big Pharma’s drugs has no legitimate basis.
