I have come across this statement. I wonder if it would cause some people to be misdiagnosed?
bbc.co.uk/news/health-29718618
The doctor on the link states:
Dr Brian Hope: "I don't think for one minute ..[people] would make a false diagnosis in order to earn £55"
More to the point, I think the fact that if a patient was given a diagnosis of dementia by a GP how would that affect the person and their family if a mistake was made? The patient could just have a problem due to T3 deficiency.
Mind you. thousands who have a dysfunctional thyroid gland may remain undiagnosed and of that we are sure.
