Exactly.
You get all this sort of overt nonsense from so called medical professionals as soon as you leave the door open to some psychological influence on a neurological disease. Nonsense like blaming the family for the disease, or blaming the patient for allowing his state of mind to somehow create the disease.
These medical professionals that believe this nonsense are still living in the dark ages.
Now, I am prepared to accept that factors such as psychological stress might conceivably play a role in disease etiology (but for
physiological reasons, such as the fact that stress may increase viral reactivation). However, stress is a relatively clearcut concept.
Whereas psychologists that hold somatoform views on disease think that your beliefs and values can cause illness, which is really a form of mumbo-jumbo
magical thinking rather than science. And this is why they then start blaming the patient, and the blaming the family for the disease, because they have these magical thinking ideas that mere belief can create a disease.
So in practice, it is better not to leave the door open to psychological / psychosocial factors in your theory of a neurological disease, because in practice, when you do leave the door open (as Yunus unfortunately did with CSS), the psycho-quacks come out of the woodwork.
