  • My Letter to Author of CODES Commentary

    Earlier today, I sent the following letter to Dr David Perez, a neurologist and psychiatrist at Massachusetts General Hospital in Boston. Dr Perez, an expert on functional neurological disorders, wrote a commentary for Lancet Psychiatry that accompanied the publication of the results for CODES, a major study of cognitive behavior therapy as a treatment for…

  • More Questions About CODES Trial of CBT for Seizures

    [*In the last paragraph, I mistakenly referred to the CODES protocol rather than the CODES statistical analysis plan. I apologize for the error.] I have recently written about CODES, the high-profile clinical trial investigating whether cognitive behavior therapy (CBT) could reduce the frequency of dissociative seizures, also known as  psychogenic non-epileptic seizures. The trial, published…

  • BMJ Responds to Appeals About Norway’s CBT-Music Therapy Study

    Earlier this week, I sent a nudge to Professor Imti Choonara, editor-in-chief of BMJ Paediatrics Open, and Fiona Godlee, editorial director of BMJ, about a problematic “feasibility study” published a few months ago. That followed a letter two weeks ago, to which I had not received a response. Previous posts on this issue are here…

  • Trio of Trials Shows Limits of CBT for Medically Unexplained Symptoms

    Lancet Psychiatry recently published the results of a high-profile trial of cognitive behavior therapy as a treatment for so-called dissociative seizures, also known as psychogenic non-epileptic seizures. The trial, nicknamed CODES, found that CBT had no impact on seizure frequency–the primary outcome. The average number of seizures per month dropped in both the treatment and…

  • A Letter to KCL, Another Letter to BMJ

    Last week, I wrote about a troubling press release issued by King’s College London regarding a major study of cognitive behavioural therapy as a treatment for so-called dissociative seizures. On Friday, I sent a letter to the two communications people listed on the press release about the study, as well as to the corresponding author.…

  • A Couple of Blog Posts Worth Reading

    I’ve been writing about so-called “medically unexplained symptoms,” or MUS, for the last couple of years. Much of that has come in the form of critiques of specific studies making excessive claims about the healing powers of cognitive behavior therapy. Recently, a blogger named Goodelf has posted a couple of revealing posts about the overall…

  • Tack’s Take on BMJ’s CBT-Music Therapy “Feasibility Study”

    I have always made it clear that I pay attention when smart patients assess bad research. That’s how I stumbled into this whole mess in the first place–by reading what patients were writing about the PACE trial. (In that case, I at first dismissed the concerns when I read about how participants could get worse…

  • My Letter to Peer Reviewer of BMJ’s CBT-Music Therapy Paper

    I have recently written a few posts–here, here and here–about a study in BMJ Paediatrics Open that appears to be marred by multiple methodological and ethical problems. This is certainly not a one-time occurrence when it comes to BMJ journals. Last week, I sent a letter to the study’s senior author inviting him to send me his response…

  • Questions for Dr. White and his PACE Colleagues

    I have been seeking answers from the PACE researchers for more than a year. At the end of this post, I have included the list of questions I’d compiled by last September, when my investigation was nearing publication. Most of these questions remain unanswered. The PACE researchers are currently under intense criticism for having rejected…
