I was able to attend Wyller's two lectures at this conference and took notes.
I've only read interviews, papers and debate articles from him, never attended a lecture before, so was curious what he would say when he had a big stage and and hour in total at his disposal.
I was not very impressed by his explanatory model for ME, and surprised that he still defends the PACE trial and recommends Lightning Process.
Here are some of the notes translated into English.
Fatigue model
Wyller did underline that what he has to offer is a model, that a lot of his research is based upon that model, and that they are far from being able to draw any conclusions.
The brain has automatic interpretations of what is happening in the body and expectations to what is going to happen. Sometimes they can be mistaken.
Whether an alarm is activated in an appropriate or inappropriate way, it will give a bodily stress response, as these are signals of danger. This again will lead to a change in the autonomic nerve activity, of the cortisol system and the immune system.
The immune system is not only what can cause fatigue, it's also affected by stress. The communication goes both ways. Our brain and hormonal system also controls the immune system.
Based on this they have suggested a complex model for fatigue. They try to put together everything they know empirically to a whole where personality, infections and life events cause the alarm to get jammed. This results into symptoms and a bodily stress respons, a sustained arousal which again leads to cognitive changes, autonomic changes, hormonal changes and in fact a low degree inflammation.
The patients
Many of these patients are ambitious, conscientious, a bit perfectionist. He meets many who will continue to study medicine or psychology or something similar, and exercise and have a thousand friends on Facebook. They do all this despite being sick. We are like animals in the sense of Pavlov’s rats (sic). We too have automatic learning. If you continue to expose yourself for strain that makes you tired while you have an infection, it’s easier to imagine that you via classical conditioning start to associate differently. Suddenly the infection has vanished, but then you get unusually tired from other things, because you have made a connection to it in your brain with having an infection.
He talks about a patient who had sent him a letter saying:
I went in and out of the hospital for two months due to mononucleosis. I became very attentive to my own body and started to consider myself as fragile. I became a master in listening to my body. If I experienced that something made me worse, I became more careful next time. Everything was about cause and effect. Mental training made me question my ideas on cause and effect. It made me do things I previously had thought were beyond my limits, without believing or being afraid of getting a reaction. And then I didn’t get a reaction.
This patient had been 1 1/2 years in a nursing home as a severe ME patient and recovered by Lightning Process. Wyller thinks this is a non medical version of the meaning of rumination.
Predicting future fatigue in patients with mononucleosis
He talked among other about his trial on mononucleosis and ME where adolescents were followed up for 6 month after the infection. He said that how you experience your symptoms in the beginning, how sensitive you are for light and sound for instance, predicts how tired you are after six months.
And more important; how anxious you are. If you worry a lot when you have mononucleosis, you will become more tired after six months. And also how well you remember. If you have a good memory, you will be more tired. He believes this corresponds with fatigue being an alarm caught in a jam. If you worry a lot, you will feel more fatigue. You will worry it won't pass, then start to expect it won't pass.
Criteria and prognosis
He believes fatigue is fatigue. It makes no sense to try splitting the long lasting fatigues into a lot of sub groups based on diagnoses. He prefers simple diagnostic criteria and criticises the Canadian criteria.
He believes that if you have a long term fatigue consequential for daily activities which can't be explained by other current physiological or psychological illnesses, then you have an unexplained fatigue or what is called CFS/ME. A lot of British researchers agree with him.
It’s important to offer empathy, hope and explanations. It’s a serious condition and there’s no solutions as simply thinking oneself better. But one can recover.
Many children and adolescents, in fact most of them, recover. It's important to tell them that, considering the importance of expectations.
Treatments, PACE and Lightning Process
Cognitive behaviour therapy is not just about dealing with a situation. With psychotherapy you can change the brain’s chemistry and function. Therefore cognitive therapy is just as good treatment as drugs.
Fatigue is real and not imaginary, even if it can’t be measured.
It’s important to underline that talking about body, mind and social structures is science and no capitulation for alternative medicine. In a biopsychosocial context, dividing treatment and coping is meaningless. Coping is treatment. Psychotherapy has biological consequenses and vice versa.
Cognitive therapy is the only thing that has been properly documented scientifically.
Many know of the PACE trial from 2011. A big British study that clearly showed cognitive behavioural therapy was better than other treatments. The PACE trial has been much critisised. Completely unreasonably and it has been absolved legally, ethically. It’s a great study. Published in the Lancet and still standing as an important study in this field.
He then went on to praise the FITNET study.
The LP study shows the same. LP is a phenomenon with cognitive techniques and other things, as positive psychology, etc. It is based in a bit alternative tradition, but has gradually gotten a pretty good academic, theoretical basis and has proven empirically to be useful. One of the things that can make Lightning Process very useful is that it makes patients experience that they can do something without becoming tired. It’s a learning-psychological effect in being tricked into do an activity and experience it as positive and suddenly no longer thinking about actually not being able to do it due to negative expectations. All of a sudden you’ve done it after all, and by that learned something different.
These patients deteriorate by advice as going for a run. Many will do that, because they are conscientious but then they just become worse. Then the reaction often is the opposite to lay oneself flat down and not daring to do anything, and obviously no one will get better by such approach.
