I agree with this article. Just because they don’t know exactly which chemicals are imbalanced or if they are, they presume it to be true and try different medications to help. It’s a very inexact science and can be extremely frustrating. But to say that chemical imbalances DO NOT EXIST is bullshit and insulting to those of us that suffer with it. I should not be made to feel bad because I had a pretty idyllic childhood with parents that were loving, supportive and fun. It’s a genetic lottery and for some of us our number comes up. It’s pretty simple. If I don’t disagree with you for believing that you’re depressed because you had shitty parents or cause something bad happened to you, don’t tell me chemical imbalances don’t exist. Now if you don’t have this type of illness and you are like my Uncle who used to believe there was no such thing as depression? LOL That kind of ignorance ACROSS THE BOARD I can totally understand. But you don’t get to pick and choose that your type of depression exists while my type doesn’t.
CHEMICAL IMBALANCES: REAL OR IMAGINED?
by Pete Earley
One of the first phrases parents hear when a loved one shows symptoms of bipolar disorder, schizophrenia or persistent and major depression is “chemical imbalance.” I remember being shocked when I wrote this term in a Washington Post Op Ed piece and was confronted by someone who told me there is absolutely no scientific evidence that mental illnesses are caused by chemical imbalances in the brain.
So I was happy when I received an advance copy of the book: SHRINK RAP: Three Psychiatrist Explain Their Work written by psychiatrists: Dinah Miller, Annette Hanson, and Steven Roy Daviss, who write a popular mental health blog. I found their comments about “chemical imbalances” helpful.
“Chemical imbalance is a term with imprecise meaning…Saying that a psychiatric disorder is caused by a chemical imbalance, although an imperfect explanation, sometimes makes psychiatric disorders more palatable to patients and less stigmatizing. The term gives some credence to the practice of treating these disorders with medication. But there is no psychiatric disorder for which we know for certain which chemicals are “imbalanced” if any.
“We have reasons for believing that psychiatric disorders must certainly be mediated by biological factors. For one thing, psychiatric illnesses run in families, even when family members are separated at birth. Research has shown that genetic links, and even specific genes, may be associated with different disorders. Many studies have shown that the biological features of groups of people with illnesses are different from those same features in groups of people without those illnesses. What we don’t have, yet, is a specific reliable test for a certain genotype or enzyme level, or a brain scan finding that indicates that a specific person has a specific disease.”
The authors explain that if a person goes to the doctor because of increased thirst or urination and has a lab test done, and it shows markedly elevated blood sugar levels, then that patient most certainly has diabetes. But with a few rare exceptions, such as Huntington’s disease or Jacob-Creutzfelt dementia, there’s nothing like this in psychiatry — no blood test, no x-ray, no CT scan that yields a definitive diagnosis. In psychiatry, blood tests are ordered to rule out medical conditions that masquerade as psychiatric illnesses — especially thyroid conditions or high ammonia levels — or to monitor medication levels to make sure medications are not damaging a patient’s organs.
“We know that the medications used to treat mental illnesses alter the levels of certain neurotransmitters. The antidepressant Prozac increases levels of serotonin in the brain. We don’t know for sure that depression is caused by low levels of serotonin, or that raising these levels is the mechanism that helps to alleviate the symptoms, but many lines of evidence suggest such a connection. In simpler terms, we presume there is a ‘chemical imbalance,’ but it remains uncertain as to what that imbalance actually is. Serotonin may be just one step in the final common pathway, along with many other steps, that contribute to the syndrome of depression. Simply said, we don’t know the exact biological nature of what is wrong when someone has a mental illness; nor do we know for certain the exact mechanism by which medications or other treatments work.”
I agree with the Shrink Rap doctors. The term “chemical imbalance” is short-hand used by laypersons to describe what we can’t scientifically explain. We know something is awry in someone’s brain when he/she shows symptoms of bipolar disorder, schizophrenia or severe and persistent depression. We know chemicals often can help alleviate these symptoms. Ergo, we conclude the symptoms are the result of a “chemical imbalance” when the truth is that we don’t really know what is happening, only that something is.
I was fortunate enough to speak to Dr. Eric Kandel, the Nobel Prize winning doctor, who appeared on Minds on the Edge when it was produced by Fred Friendly Seminars. Dr. Kandel acknowledged that science simply hasn’t yet been able to discover the “biological underpinnings” of major mental disorders. But our lack of knowledge doesn’t mean a link doesn’t exist, he said. He asked why we continue to separate the brain from the rest of the body when we think of biological illnesses and genetic links. Why do we accept that they play a role in everything that happens beneath our chin but argue that they can’t be influencing our brains? The real tragedy, Dr. Kandel explained, is that medical research in nearly every other area of the body has moved forward significantly with the exception of our brains.
