Dr Caroline Leaf – The Christian church’s anti-vaxxer

Well, this is my first post for the new year.  2016 was certainly historic!

In 2016, the Oxford Dictionaries Word of the Year was “post-truth”.  Post-truth describes the concept “in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief”.

While the popularity of the word rose in step with the popularity of the US President-Elect, post-truth as an idea has been building more and more over the last decade or so.  It’s the driving force behind other cultural phenomena of our modern world, like the alternative health and the anti-vaccination movements.

It’s also the secret to the success of Caroline Leaf.

Dr Caroline Leaf is a communication pathologist and self-titled cognitive neuroscientist.  She’s been riding the wave of our post-truth culture for years.  Dr Leaf has a set of slickly spoken mistruths that form the basis of her ministry, and are repeated constantly (including, but not limited to):

The mind controls the brain
75-98% of all physical, mental and emotional illnesses come from our thought life
The heart is a mini-brain
Our mind changes matter through quantum entanglement
ADHD and depression aren’t diseases
Anti-depressant medications are dangerous placebos

There is no scientific evidence to support any of these claims, but that hasn’t stopped her claiming, because Christians and the leadership of the Christian church believe her without question.

In the last twenty-four hours, Dr Leaf put up two separate social media posts which follow the same pattern – repeated mistruths with no basis in fact.

“What an honor to be speaking at the annual Noiva humanitarian foundation conference in Winterthur, Switzerland, which works actively with the Syrian refugees seeking to broker peace in the Middle East.  I spoke about how showing compassion and helping others improves brain health and increases physical and mental healing by around 63%!”

Showing compassion and helping others improves brain health and increases physical and mental healing by around 63% hey?  I’m assuming she’s referring to the study by Poulin et al [1], because she’s posted this to her social media feed before, and there aren’t any other studies out there that show compassion and helping others increases physical and mental health so much … not that the Poulin study showed it either (not even close – https://cedwardpitt.com/2016/10/27/dr-caroline-leaf-credit-where-credits-due/ and https://cedwardpitt.com/2016/01/16/does-helping-others-help-you/)

On the photo she put up on social media to gloat about her little jaunt to Switzerland, the Powerpoint in the background reads, “Can the mind change the brain?”  Again, the answer is a clear ‘No’!  She tried to argue the same nonsense in her TEDx talk in early 2015 (https://cedwardpitt.com/2015/03/26/the-tedx-users-guide-to-dr-caroline-leaf/).  It was wrong then, and it’s still wrong now.

Unless Dr Leaf’s found some better resources, NOIVA should ask for their money back.  They could have fed a lot of refugees for the wasted cost of hosting Dr Leaf at their conference.

Dr Leaf’s second social media post was even more egregious.

“Our genetic makeup fluctuates by the minute based on what we are thinking and choosing.”

WRONG!  Absolutely wrong.  There is NO scientific evidence that supports this statement at all (https://cedwardpitt.com/2014/09/27/dr-caroline-leaf-and-the-genetic-fluctuations-falsehood/).  DNA is stable.  It doesn’t “fluctuate by the minute”.  It’s not influenced by our thoughts or our choices.

We may be stuck in a post-truth world but science is not, and will never be, post-truth.  Your belief in the cancer-fighting properties of turmeric doesn’t make turmeric cure cancer.  Your opinion that the MMR vaccine causes autism doesn’t change the concrete scientific evidence that it doesn’t.

By the same token, Dr Leaf might believe that our thoughts and choices change our DNA, but it doesn’t matter how many times Dr Leaf repeats the same fiction, it still doesn’t make it fact.  She can repeat ad nauseum her belief that the mind controls the brain, or our mind changes matter through quantum entanglement, or depression isn’t a disease, or all of our illnesses come from thoughts.  None of them were true the first time she made each outrageous claim, and they still aren’t true now. Scientific truth doesn’t change depending on what suits your opinion.

In fact, all Dr Leaf is doing by continually perpetuating her stock of mistruths is to disempower her audience.  Rather than encourage people to follow the facts, they are sucked into a vortex of wasted money and time.  Precious resources are spent chasing wild geese instead of putting them towards something more meaningful.  NOIVA diverting funds to support Dr Leaf’s fees instead of feeding refugees is a perfect case in point.

Worse, Dr Leaf’s teaching discourages people from taking effective medications and seeking effective treatments which can only lead to greater suffering in those who are vulnerable.

In this sense, Dr Leaf is like the anti-vaxxer of the Christian church, discouraging her followers from seeking scientifically sound treatments in favour of belief in erroneous and invalid actions with no proof of efficacy and a real risk of harm.

When will the leadership of the Christian church stand up for their parishioners and stop Dr Leaf’s fictions from infecting their churches?  The answer should be ‘now’, and that’s a fact.

Where do you draw the line? On vaccination and freedom of speech

I was skimming my Facebook feed this afternoon, and I had to take a second glance at one of the articles when my brain eventually caught up with what was on the screen.

Australian nurses who spread anti-vaccination messages will now face prosecution”, it said.

My first reaction was, “Wow … that was unexpected.”

So unexpected, in fact, I initially thought it was a hoax.  Then I noticed the story was being reported by several sources, some of which looked reputable.  Perhaps this wasn’t a viral meme after all.  I went to the Australian Health Practitioner Regulatory Authority’s website to get direct confirmation, and sure enough, it was no joke—AHPRA and the Nursing and Midwifery Board of Australia (NMBA) recently issued a statement saying exactly what was reported.

“The NMBA has become aware that there are a small number of registered nurses, enrolled nurses and midwives who are promoting anti-vaccination statements to patients and the public via social media which contradict the best available scientific evidence. The NMBA is taking this opportunity to make its expectations about providing advice on vaccinations clear to registered nurses, enrolled nurses and midwives.”

“The NMBA expects all registered nurses, enrolled nurses and midwives to use the best available evidence in making practice decisions. This includes providing information to the public about public health issues.”

“Any published anti-vaccination material and/or advice which is false, misleading or deceptive which is being distributed by a registered nurse, enrolled nurse or midwife (including via social media) may also constitute a summary offence under the National Law and could result in prosecution by AHPRA.”

Vaccination is a pet subject for me—I’m a strong advocate for immunisation and I detest those who would misconstrue the science of vaccines to suit their own twisted agenda.  I think there’s a special place in hell set aside for Jenny McCarthy and Andrew Wakefield.

That said, I’m still a teensy bit uneasy about this new approach by AHPRA, because as much as I hate hearing about people mislead by anti-vaxxers, I want to protect freedom of speech.

Muzzling free speech is a two-edged sword.  Yes, you might stop slimy crack-pots like Wakefield from spreading their malicious fiction, but you also run the risk of stifling legitimate debate.

There’s no evidence that vaccines have toxic levels of mercury or aluminium, or that vaccines cause autism or cancer.  To suggest otherwise is unscientific, and I have no problems in categorically stating that vaccination opponents are currently wrong.  But … what if a legitimate concern about a vaccine arises?  I’m not suggesting the evidence for vaccination is unsettled, but rather, what if a new vaccine is developed that does have unforeseen complications?  Will gag laws prevent a whistle-blower from coming forward for fear of being tarred as “anti-vaccination”?  I wouldn’t put it past the developing drug company from using such a tactic if they wanted an easy way to defend their product.

The other aspect to consider is broader—is this the thin end of the wedge?  If we start gagging health professionals from speaking out against the consensus on immunisation, then what’s next? Abortion law reform? Euthanasia? Climate change?  Each of these issues remains controversial and each side of each issue claims to have science on its side.  Should the side with the perceived ‘consensus’ have the authority or the right to suppress debate from their opponents?

Besides, the problem of anti-vaccination propaganda goes way beyond nurses making comments on social media.  AHPRA’s power only extends to registered health practitioners in Australia.  It doesn’t stop naturopaths or “nutritionists” from promoting anti-vaccination views, and it seems it hasn’t stopped certain chiropractors from subverting the rules either.  It doesn’t stop alternative-health hawkers overseas.

Despite my misgivings, I’m still in favour of AHPRA’s move.  It’s a step in the right direction, and it’s being done for the right reasons—to protect patients from rogue operators that would betray their trust—although this edict might need further discussion before extending it to all AHPRA health practitioners.

Perhaps we should focus on promoting the truth instead of trying to suppress the lies.  For every anti-vaccination blog, there should be a hundred promoting the science behind vaccines.  For every anti-vaxxer celebrity that gets thirty seconds of air time, there should be thirty minutes of air time for reputable scientists and vaccination advocates.  Anti-vaxxers should be able to say what they want even if it’s pseudoscience, but they should be prepared to be pilloried by real scientists using proven facts.

Perhaps that’s a better way to protect all the rights of the community.

Autism Series 2013 – Part 2: The History Of Autism

“We can chart our future clearly and wisely only when we know the path which has led to the present.” Adlai E. Stevenson

I always thought history was boring, and I must admit, If you want to put me to sleep, start reading early Australian history to me. “Convicts … first fleet … zzzzzz.”

But as Stevenson wrote, the key to the future is the past. With autism, I don’t want to see a future as checkered as its past. In this series of essays, I want to help our community see a future in which autism is recognised and appreciated for its strengths. To properly lay the groundwork, I want to look at the history of autism. This will help provide context for the current understanding of autism, which will then give a framework for understanding the autistic person, and for a glimpse into the future as new research unfolds.

The autistic spectrum has been present for as long as humans have. But to our knowledge, one of the first specific descriptions of someone who met the characteristics of the autistic spectrum was in the mid 1700’s. In 1747, Hugh Blair was brought before a local court to defend his mental capacity to contract a marriage. Blair’s younger brother successfully had the marriage annulled to gain Blair’s share of inheritance. The recorded testimony describes Blair as having the classic characteristics of autism, although the court described him at the time as lacking common sense and being afflicted with a “silent madness”.[1]

Isolated case reports appeared sporadically in medical journals. John Haslam reported a case in 1809, although with modern interpretation, the child probably had post-encephalitis brain damage rather than true autism. Henry Maudsley described a case of a 13 year old boy with Aspergers traits in 1879. There were no other reports of children with autism in the early literature, although at the turn of the 19th century, Jean Itard reported on the case of an abandoned child found roaming in the woods like a wild animal. This child, called Victor, displayed many features of autism, although he may have simply had a speech disorder. Either diagnosis was obscured by the effects of severe social isolation.[1]

Others described syndromes which shared autistic features, but without describing autism itself. The names given to each syndrome reveals how autistic features were regarded in the 19th century: Dementia Infantalis, Dementia Praecocissima, Primitive Catatonia of Idiocy.[1]

Around 1910, Eugen Bleuger was a Swiss psychiatrist who was researching schizophrenic adults (and as an aside, Bleuger was the person to first use the term ‘schizophrenia’). Bleuger used the term ‘autismus’ to refer to a particular sub group of patients with schizophrenia, from the Greek word “autos,” meaning “self”, describing a person removed from social interaction, hence, “an isolated self.”[2]

But it wasn’t until the 1940’s that the modern account of autism was articulated, when two psychiatrists in different parts of the world first documented a handful of cases. Leo Kanner documented eleven children who, while having variable presentations, all shared the same pattern of an inability to relate to people, a failure to develop speech or an abnormal use of language, strange responses to objects and events, excellent rote memory, and an obsession with repetition and sameness[3].

Kanner thought that the condition, which he labelled ‘infantile autism’, was a psychosis[1] – in the same family of disorders as schizophrenia, although separate to schizophrenia itself[2]. He also observed a cold, distant or anti-social nature of the parents relationship towards the child or the other parent. He thought this may have contributed (although he added that the traits of the condition were seen in very early development, before the parents relationship had time to make an impact)[3]. True to the influence of Freud on early 20th century psychiatry, Kanner said of the repetitive or stereotyped movements of autistic children, “These actions and the accompanying ecstatic fervor strongly indicate the presence of masturbatory orgastic gratification.”[3]

Despite the otherwise reserved, cautious discussion of possible causes of this disorder, the link with schizophrenia and “refrigerator mothers” took hold in professional and lay communities alike. In the 1960s and 70s, treatments for autism focused on medications such as LSD, electric shock, and behavioral change techniques involving pain and punishment. During the 1980s and 90s, the role of behavioral therapy and the use of highly controlled learning environments emerged as the primary treatments for many forms of autism and related conditions.[2]

Unbeknown to Kanner, at the same time as his theory of ‘infantile autism’ was published in an English-language journal, a German paediatrician called Hans Asperger published a descriptive paper of four boys in a German language journal. They all shared similar characteristics to the descriptions of Kanner’s children, but were functioning at a higher level. They shared some aggression, a high pitched voice, adult-like choice of words, clumsiness, irritated response to affection, vacant gaze, verbal oddities, prodigious ability with arithmetic and abrupt mood swings. Asperger was the first to propose that these traits were the extreme variant of male intelligence[4].

But the full impact of Asperger wasn’t felt until 1981, when British psychiatrist Lorna Wing translated Aspergers original paper into English. By this time, autism had become a disorder of its own according to the DSM-III, the gold-standard reference of psychiatric diagnosis, but it was still largely defined by the trait of profound deficit. Aspergers description of a ‘high-functioning’ form of autism resonated amongst the autism community, and a diagnosis of Aspergers Syndrome became formally recognised in the early 1990’s with the publication of the DSM-IV.

The most recent history of autism comes in two parts. The first was the revision of the DSM-IV. For the first time, rather than two separate diagnoses, Autism and Aspergers have been linked together as a spectrum and collectively known as the Autism Spectrum Disorders (although autism self-advocates prefer the term ‘conditions’ to ‘disorders’).

The second part is a highly controversial chapter that will stain the history of autism research and scientific confidence, into the next few decades. Chris Mooney, in a piece for Discover Magazine, sums it up nicely:

“The decade long vaccine-autism saga began in 1998, when British gastroenterologist Andrew Wakefield and his colleagues published evidence in The Lancet suggesting they had tracked down a shocking cause of autism. Examining the digestive tracts of 12 children with behavioral disorders, nine of them autistic, the researchers found intestinal inflammation, which they pinned on the MMR (measles, mumps, and rubella) vaccine. Wakefield had a specific theory of how the MMR shot could trigger autism: The upset intestines, he conjectured, let toxins loose in the bloodstream, which then traveled to the brain. The vaccine was, in this view, effectively a poison.”[5]

Inflamed by a post-modern distrust of science and a faded memory of what wild-type infectious diseases did to children, the findings swept through the internet and social media and lead to a fall in vaccination rates (from about 95% to below 80% at its lowest)[6].

But the wise words, “Be sure your sins will find you out”, still hold true, even in modern science. In 2010, Wakefield was found guilty of Serious Professional Misconduct by the British General Medical Council, and was struck off the register of medical practitioners in the UK. In the longest ever hearing into such allegations, the GMC considered his conduct surrounding the research project, the medical treatment of his child subjects, and his failure to disclose his various conflicts of interest to be dishonest and professionally and clinically unethical[7]. There is evidence that he also selectively chose his subjects to confound the results, misrepresented the time course of their symptoms related to the vaccinations, misrepresented their diagnosis of autism, and altered the reports of their bowel tests[8, 9].

For the record, this isn’t a comment on the science of Wakefield’s rise and fall, but the history. I am not suggesting that the proposed autism/vaccination link should be discounted solely on the basis of Wakefield’s scientific fraud. Rigorous science has already done that. The science for and against the proposed link between autism and vaccinations deserves special attention, and will be discussed in a future post. Rather, lessons need to be learned from what is one of the most destructive cons in the recent history of medicine.

The losers of this hoax are twofold. Thousands of children have unnecessarily suffered from preventable infectious disease because of a fear of vaccines that has turned out to be unfounded, and those who actually have autism miss out on actual funding because it was syphoned off into Wakefield’s pockets and into research disproving his rancid theory. As the editorial in the BMJ stated, “But perhaps as important as the scare’s effect on infectious disease is the energy, emotion, and money that have been diverted away from efforts to understand the real causes of autism and how to help children and families who live with it.”[6]

As with all good history, there are lessons for the future. Autism is still largely misunderstood. The vacuum of definitive scientific knowledge is slowly being filled, gradually empowering people with autism and the people that interact with them to truly understand and communicate. Each breakthrough and revision of the diagnosis has lead to more sophisticated and more humane ways of living with autism. But there is still a need for caution – people will use the gaps in knowledge and the pervasive distress that can come from the diagnosis, to manipulate and exploit for their own ends.

I’ll continue with the series in the next week or so, looking at the modern “epidemic” of autism.
