Dr Charles Shepherd, a world renowned expert on ME/CFS, is the honorary medical advisor to the ME association - the health charity that advocates for people affected by the illness.
He says his view is that Long Covid is an ‘umbrella diagnosis’ which covers ‘a very wide range of clinical presentations’. At one end of the spectrum, he says, are people who have been in hospital with severe lung or heart complications from which they have not recovered and now have persisting symptoms to do with the heart and lungs - such as breathlessness and chest pain.
“At the other end of the spectrum are people who caught Covid, were managed at home and may not have been that ill, and have gone on to develop a fairly short lived post viral fatigue syndrome from which they have improved or recovered, or have developed an ME/CFS like illness from which they are not recovering,” he adds. “There are others who have both components, or have developed a post Covid psychiatric illness.”
Dr Shepherd, who developed ME after catching chickenpox from one of his hospital patients around 40 years ago, goes on to say that he provided Paul with some ‘information and guidance’ on how to manage his activity during the early stages of his illness, ‘which he found helpful’. Paul wrote about this in one of his
early BMJ blogs on the subject.
“As with a proportion of people with Long Covid he has eventually improved and recovered,” Dr Shepherd adds. “But I don't believe that one person's experience of what works and what does not work can be translated to everyone with a diagnosis of Long Covid.
“As far as ME/CFS is concerned, the idea that this is a psychosomatic illness that is perpetuated by abnormal illness beliefs and behaviours has been rejected by NICE, MRC, DHSC and most medical opinion. And I don't believe that this sort of psychosomatic model of causation applies to Long Covid either.”
