Monkey business in autism research

NOTE: I had originally planned on posting Part II of a series on cancer screening. However, something came up on Friday that, in my estimation, requires a timely response. I should also inform readers that, because next Monday is a holiday here in the U.S., I haven’t yet decided whether I will be doing a post next week or not. Stay tuned...

Near Death Experiences and the Medical Literature

MIRACLE MAX: See, there’s a big difference between mostly dead, and all dead. Now, mostly dead: he’s slightly alive. All dead, well, with all dead, there’s usually only one thing that you can do. INIGO: What’s that? MIRACLE MAX: Go through his clothes and look for loose change. — The Princess Bride Can you trust anyone when they purport to tell you...

On Being Certain

Neurologist Robert A. Burton, MD has written a gem of a book: On Being Certain: Believing You Are Right Even When You’re Not. His thesis is that “Certainty and similar states of ‘knowing what we know’ arise out of involuntary brain mechanisms that, like love or anger, function independently of reason.” Your certainty that you are right has nothing to do with...

Mercury emissions from coal-burning power plants and autism: Is there a correlation?

On April 30, outside the courthouse in Dallas, a press conference/rally was held. This particular rally was in response to a new study published by a group led by Dr. Raymond F. Palmer in the Department of Family and Community Medicine at the University of Texas Health Science Center in San Antonio, whose conclusion was that autism prevalence correlates strongly with proximity...

The North Carolina Board of Medical Examiners, Dr. Rashid Buttar, and protecting the public from practitioners of non-science-based medicine

One of the most contentious and difficult aspects of trying to improve medical care in this country is enforcing a minimal “standard of care.” Optimally, this standard of care should be based on science- and evidence-based medicine and act swiftly when a practitioner practices medicine that doesn’t meet even a minimal requirement for scientific studies and clinical trials to support it. At...

The Increase in Autism Diagnoses: Two Hypotheses

A new study sheds more light on the question of what is causing the recent increase in the rate of diagnosis of autism. Professor Dorothy Bishop from the University of Oxford studied adults who were diagnosed in 1980 with a developmental language disorder. She asked the question – if these people were subjected to current diagnostic criteria for autism, how many of...

SPECT Scans at the Amen Clinic – A New Phrenology?

Phrenology was a 19th century pseudoscience that claimed to associate brain areas with specific personality traits. It was based on palpating bumps on the skull and was totally bogus. New brain imaging procedures are giving us real insights into brain function in health and disease. They are still blunt instruments, and it is easy and tempting to over-interpret what we are seeing....

Cell Phones and Brain Tumors

The question of whether or not there is a link between the use of mobile phones (also called cell phones) and the risk of brain tumors has been cropping up more and more frequently in the media – every time a new study or analysis comes out. This is a very important question of public health as cell phone use is becoming...

Thoughts on Neuroplasticity

I recently read a fascinating book, The Brain That Changes Itself by Norman Doidge. He describes case histories and research indicating that the brain is far more malleable than we once thought. We used to think each function was localized to a small area of the brain and if you lost that area of brain tissue the function was gone forever. We once thought...

Do Antidepressants Work? The Effect of Publication Bias

A recent meta-analysis of the most commonly prescribed antidepressant drugs raises some very important questions for science-based medicine. The study: Initial Severity and Antidepressant Benefits: A Meta-Analysis of Data Submitted to the Food and Drug Administration, was conducted by Irving Kirsch and colleagues, who reviewed clinical trials of six antidepressants (fluoxetine, venlafaxine, nefazodone, paroxetine, sertraline, and citalopram). They looked at all studies...
