The Norwegian news site Nettavisen had an
article about Long Covid yesterday titled: "Long covid": normal bodily conditions may be interpreted as symptoms
The article is behind paywall, so here's a summary:
Researchers say that media articles, negative messages from the doctor and discussions among post covid sick people on social media can be an important cause of the condition, due to the nocebo effect.
PhD student Mesier Hojjat Daniali co-authored a study from 2021 showing that the more people believe they had Covid, the more they felt symptoms. Also that the more anxiety people had before assessment, the more and stronger symptoms they got.
Another study referred to is from JAMA psychiatry and shows that worrying about covid-19, anxiety, stress, depression and loneliness increased the probability for experiencing self reported post covid ailments with 50% compared with people without these stress factors.
A third study referred to in the article showed that worry over Covid was a more important cause of insomnia than the virus infection itself. Insomnia is one of the 200 symptoms tied to "long-covid".
Daniali concludes that the cause of "long covid" can be explained as a combination of biological, psychological and social factors.
The Norwegian Covid Association is in the article described as "exclusively referring to research that supports the hypothesis that physiological conditions in the body caused by the infection covid is the cause of "long covid"".
Professor in psychology (and LP researcher) Silje Reme says the research is pointing more towards psychological and social factors as explanations for Long Covid than biological factors. Biology, as for instance individual vulnerabilities, due to genes or childhood trauma, can influence how sick you get from covid-19.
Professor Egil Fors agree and says the conditions for long covid are:
- genes
- life experiences as bullying and trauma in childhood
- a trigger, for instance a virus infection with covid
- maintaining factors, as though patterns or economical circumstances
Then senior doctor and professor Preben Aavitsland from the Norwegian Institute of Public Health says the same goes for borrelia, and that there's no such thing as a tick epidemic and chronic borrelia. The contagion comes from internet, not the woods.
Professor Reme says that increased attention to symptoms and pain create symptom network in the brain, just like highways with their main task being to focus on the symptoms.
Professor Fors says in order to get better you have to do some changes, not just wait for improvement. You have to work with "yellow flags" as:
- catastrophising as in thinking that pain is harmful or dangerous and that it increases with activities
- misinterpretation and increased awareness towards bodily symptoms
- talking about one's problems
- not being physically active and getting a lot of rest
- bad sleep
- having small economic gain of returning to work
- having night work and little autonomy at work
- having a poor social network
- having an overprotective spouse
These yellow flags maintain chronic pain in many different conditions because they raise the stress activation in the body, which can increase the pain intensity. It can be fibromyalgia, chronic borrelia, chronic back pain, and "long covid".
And then the article ends with Professor in psychology Gerd Kvale who has developed a quick CBT for anxiety and OCD which also works for Long Covid. The subtitle is: A cure that works.
