They Stored and Studied Thousands of Brains, But Still Failed to Show Mental Illness Comes From Sick Brains

In 2019 the Washington Post had a long article entitled "Dissecting brains to find the biological answers to the mysteries of mental disorders."  We hear about a Lieber Institute of Brain Development that is engaged in the strange business of requesting brains from the relatives of those who very recently died, and then studying such brains.  But we read nothing substantial in the Post story about any progress made in understanding mental illness by studying brains.   We are told, "Since opening in 2011, the institute has amassed more than 3,000 of these post-mortem brains that they are studying to better understand the biological mechanisms behind such neuropsychiatric disorders as schizophrenia, major depression, substance abuse, bipolar disorder and post-traumatic stress disorder."  

We are told of a guy working for that institute who has the job of calling the families of people who just died (often from suicide), asking them to donate the brain of the dead person. We are told such pleas must occur very quickly. The article says this guy "has a small window of time in which to get that consent — just one to three hours." We can only imagine how many families have been bothered in their worst hour of grief by such requests. Later the Post story makes it sound like some of the brains gathered are not that fresh, saying, "Researchers try to obtain brains within 24 to 36 hours." We are told the brains are "flash frozen." A 2019 annual report of the Lieber Institute tells us, "After consent, we obtain a detailed clinical history via interviews with the family." I can only imagine what a burden that would be on family members with a recently deceased relative. 

page of the Lieber Institute brags that it now has a collection of 4000 brains. Another of its pages calls this collection "the largest collection of brains in the world that’s devoted to enhancing science’s understanding of psychiatric disorders" (which doesn't seem accurate, since the Dutch collection described below, existing for the same purpose, is twice as large). A page of the Lieber Institute entitled "Important Breakthroughs" mentions nothing very substantial about finding a link between brain structure and mental illness. 

The site has a link to a "10-Year Anniversary Report" that fails to report much of any real progress in finding a link between mental illness and brains. We have in the report a page with a big headline of "KEY PUBLICATIONS."  The first publication listed in this report has a title of "Electrophysiological measures from human iPSC-derived neurons are associated with schizophrenia clinical status and predict individual cognitive performance." It's a Questionable Research Practices study that used a sample size of only 13 subjects.  We read in the study, "The sample sizes were small and, because there were no similar prior studies, we could not reasonably estimate expected effect sizes or error rates." The study says, "Due to the small sample sizes and the number of tests performed, some of the associations observed may be spurious, so replication studies with larger samples are necessary to confirm and extend these findings." And this is what the Lieber Institute is offering as the first example of its work in their 10-year progress report?  The other three studies mentioned on the page only talk about claims of genetic differences. 

The 10-year report has this not-very-wise comment on suicide:

"There is certainly a genetic component to suicide, meaning that it can run in families. Twin studies, however, have shown there is more to it. Scientists believe epigenetics—the interaction of genes and the environment—is at play. Perhaps early trauma or illness can turn on specific genes, increasing a person’s risk of suicide. Until we unravel the biological mechanisms underlying suicide, it’s hard to fully understand, treat, or prevent it."

The idea of suicide being caused by genes is nonsensical, as are all ideas of some idea or behavior being caused by genes. Genes merely specify low-level chemical information such as the amino acid sequence of proteins, not any tendencies to think or act in a particular way.  A gene may help make possible some physical action, but is never the cause of such an action. The idea of a genetic basis for suicide is nonsensical according to the assumptions of Darwinism. According to such assumptions, if there were any gene tending to cause suicide, natural selection would tend to weed out such a gene, reducing its occurrence of such a gene in the gene pool of humans. But suicide is still a widespread phenomenon, and it is estimated that 1.7 percent of people in the US die by suicide.  The person claiming a genetic basis for suicide is as misguided as a person claiming a genetic basis for homosexuality. It's the same situation in regard to homosexuality: if there were a genetic basis for it, we would expect (according to Darwinian assumptions) for homosexuality to be very rare or nonexistent. Instead it is estimated that 5% or more of the population is homosexual. 

bad brain explanations
Ignoring socioeconomic causal factors

The 10-year Lieber Institute report says, "Lieber scientists ask what happens in the brain that makes some people take their own lives." That's a question making an implausible assumption, and what we should be asking is: what goes on in the mind or what occurs in a person's life history or current life situation that might make him suicidal?  There is no evidence that something occurring in a brain causes people to commit suicide. 

The 10-year Lieber Institute report has a link to a paper entitled, "Genetics and Brain Transcriptomics of Completed Suicide." The "Brain Transcriptomics" part involves the ridiculous procedure of trying to analyze rates of gene transcription activity in the brains of people who have already died, using brains frozen 12 to 24 hours after death.  Gene transcription is greatly altered by death, and rapidly trails off in the hours after death. The idea that you can shed some light on what was happening in either the minds or brains of people when they killed themselves or beforehand by studying gene transcription rates in brains frozen 12 to 24 hours after they died seems likes nonsense. 

A paper like this should not be taken seriously by anyone unless the authors followed a careful blinding protocol so that those analyzing the brains did not know whether any particular brain came from someone who committed suicide. We read of no such thing. There is merely a single sentence saying, "All diagnoses and decisions about manner of suicide were determined blind to any of the molecular data." That does not mean that people studying the brains were blind to whether suicide occurred. 

Very ridiculously, the 10-year Lieber Institute report has a line saying, "Lieber researchers are looking at these biological snapshots of what occurred in the brain at the moment of suicide completion to determine what's different about these brains."  The brain of a dead person frozen 12 to 24 hours after he died is not a biological snapshot of what occurred in the brain at the moment of suicide. 

The publications page of the Lieber Institute lists their top papers for the past nine years. We seem to find no mention of a discovery linking brain states and mental illness. Most of the papers mention only claims about genes. None of the papers listed uses the word "replication." What the Lieber Institute mainly seems to have in its research is gene analysis, particularly the weak borderline type of gene analysis called transcriptomics. Transcriptomics is some not-very-solid-seeming branch of inquiry that tries to analyze what genes were being used at particular times.  The idea of trying to use transcriptomics to study dissected dead brains is laughable. Gene transcription is greatly changed by death, and trails off not long after death. 

What do you do when you can't find differences in brain size or brain structure to explain mental differences? Maybe you look for differences in genomes. But the genes in genomes merely specify low-level chemical information such as the amino acid makeup of proteins,  and have basically nothing to do with mental states. What do you do if you cannot find differences in genomes to explain mental differences? Then maybe as a last resort you do some studies on the will-of-the-wisp, ever-changing kind of thing called "transcriptomic profiles." Since transcriptomic profiles are ever-changing, and it is possible to get a separate  "transcriptomic profile" for any of 20,000+ genes, you will have some very noisy data allowing you to see pretty much anything that you want to see. 

Apparently no drugs or treatment for mental illness have yet resulted from all this studying of 4000 brains.  On a page of the Lieber Institute we read this

 "Seven years of operations, we have made considerable progress in identifying and developing a promising set of novel therapeutic targets including two that could be in clinical trials within two to three years. In addition, we have four promising leads that could introduce two new drugs into Phase II clinical trials by 2021."

That isn't a report mentioning that any drug had yet been developed by such brain studies. We hear of four drugs "out-licensed for further development," but we don't hear of any drug that has been federally approved. Apparently all this annoying the families of just-deceased people for a brain donation isn't getting much of anywhere in establishing a link between brain states and mental illness. 

The Lieber Institute publishes a free online magazine called neuroDEVELOPMENTS. In the March 2019 edition we have the very untrue claim that "the genome guides construction of the brain." The human genome (DNA and the genes in it) do not guide or specify the construction of either any human organ or any human cell. The claim that DNA is a blueprint telling how to make a body or any of its organs or cells is a grotesque lie that materialist scientists have been telling for 70 years.  For a long list of quotes by scientists and doctors saying that DNA is not a blueprint, program or recipe for building a body, see my post here

Elsewhere in the world is an even bigger collection of brains, one that also has failed to substantially support claims of a brain basis for mental illness. The Japan Times tells us this:

" Countless shelves line the walls of a basement at Denmark's University of Odense, holding what is thought to be the world's largest collection of brains. There are 9,479 of the organs, all removed from the corpses of mental health patients over the course of four decades until the 1980s. Preserved in formalin in large white buckets labeled with numbers, the collection was the life's work of prominent Danish psychiatrist Erik Stromgren...The brains were collected after autopsies had been conducted on the bodies of people committed to psychiatric institutes across Denmark. Neither the deceased nor their families were ever asked permission."

We hear not one word about any discovery that came from studying these brains. A CNN story on the basement filled with brains tells us this:

"A 2012 study found that roughly 40% of Danish women and 30% of Danish men had received treatment for a mental health disorder in their lifetimes – though Werge estimated that number would 'almost certainly' be higher if the same study was done today. (By comparison, that same year, less than 15% of US adults received mental health services.) 

I don't think Danes are any more prone to mental illness than Americans, but it seems from the numbers above that Danish authorities have some great enthusiasm for diagnosing people with mental illness, particularly women. We may only wonder how many of the brains in the Danish collection were taken without permission from women who were wrongly put in mental hospitals. The CNN article also fails to tell us of any progress in understanding the cause of mental illness from studying such brains. A web page of the University of Odense describes the collection of brains, but fails to mention any progress that has come from studying the brains.  There is no link to any papers that were produced using such brains. 

There is another brain collection called the Human Brain Collection Core (HBCC). The collection is described here. The collection seems to consist of about 1000 brains, 700 from people who were diagnosed with mental illness. 300 of the brains are from normal people. We seem to have the same kind of method as used by the Lieber Institute. The families of people who recently died are asked to donate the brain of a family member, with a time pressure element of "we must act fast." We are told "there is no direct benefit to the family for allowing the donation." I guess such "grab the brains without paying a cent for them" stinginess is what we might expect from research neuroscientists, who nowadays pay meager  "chump change" wages to volunteers for scanning their brains in medically unnecessary brain scans that might expose them to health risks (as discussed here). 

Related to this collection is a "Selected Publications" page, apparently listing the best results obtained from studying these brains. None of the papers listed have impressive-sounding titles making it sound like any brain structure or brain condition has been found explaining mental illness. Most of the papers merely refer to obscure claims about genetics and genetic transcription.  

Of about 46 papers listed, the paper that sounds the most like something reporting a link between brain structure and mental illness is a paper entitled "Accelerated hippocampal biological aging in bipolar disorder." The paper does not report any differences in the hippocampus size or structure for those with bipolar disorder. The authors tried to look for some epigenetic difference, and initially found "Groups did not differ for epigenetic aging acceleration when considering the entire sample." After using the old "slice the study group into a smaller group, looking for statistical significance" trick, the authors were able to report a very marginal  statistical significance of just barely better than the minimum of p < .05, something that smells like p-hacking.  We can't tell how large the sample size is, because the authors haven't listed it in the abstract, and the paper is behind a paywall. This does not at all qualify as any brain difference explanation for bipolar disorder.
