So one would expect the Ministry of Defence to deny the existence of Gulf Way syndrome and it does best fosamax 70mg womens health organization, operating on the simple basis of “no bug discount 70 mg fosamax with mastercard menstruation quran, no dosh”. They not only have to survive their disease: they must also fight for elementary decency. His name is Professor Simon Wessely, consultant psychiatrist at the School of Medicine, King’s College, London. It concluded — surprise, surprise — that there is no such thing as Gulf Way syndrome. Similar points are reflected in the many online comments posted to the New Scientist. I empathise with anyone who has genuinely suffered this condition, especially when they have not had good treatment from their own doctors” “To the Editor: It remains a mystery as to why you bother including the unsubstantiated opinion provided by Dr Simon Wessely. He continues to profit from the prescription of cognitive therapy for this serious illness, despite the fact 205 that the majority of patients fail to benefit from such interventions. By any other model, insistence upon cognitive therapy as the default model for treatment should constitute malpractice” “I saw on my doctor’s notes that the symptoms were all in my ‘mind’. If they dismissed cancer this way the overpaid morons would be sued for malpractice; “Those physicians may have some red‐faced explaining to do if this research pans out” “ ’Red‐faced’ – no, they should be sued for negligence. Sophia Mirza is only one such victim, most others just sank without trace as it was ‘inconvenient’ and their death or suicides were ‘all their own fault as it was all in their heads’. Why was he so happy to ignore biomedical research which demonstrated that this disease was not a mental illness? The problem was that no‐one would fund them and allow then to continue their work. Cue great neglect, suffering, exploitation, wasted generations and premature deaths. Just as with past outrages against multiple sclerosis (and) Parkinsons, will they hell” (http://www. Didn’t he read the news – 500 blood samples form London are being tested and the figures are holding up…I have spent my entire adult life with this disease and I would like to have some illness‐free years before I die. Money put into the research has been very limited, mostly due to the political connections of Wessely, his partner and the labour party. Unfortunately there are a great many people like him who have held back the frontiers of modern research by dismissing the findings and instead promoting psychological causes” “Mr Wessely’s views. It was a truly terrible time, trying to cope with a life‐altering disability and an employer who did not care”. Viruses are an attribution free from blame…there’s no blame, no shame and no stigma…. And (mocking) here is the virus research doctor himself to protect us from that shame…. This was based on a study of just 28 participants, one of whom (psychoanalyst Susan Simon) talked of suing Straus for medical malpractice; in 1993 she was killed instantly when a truck collided with her motorised scooter on a New York city street. One comment about Johnson’s article on Straus may be pertinent: 207 “Just because one is blessed with a keen mind and is granted a position of importance, it very obviously does not preclude the psychopaths, the bigots, the narrow minded or just plain xenophobic from taking control of areas of public office that have great bearing upon everyone’s lives. And by that I mean that people such as Straus should step out of the way when they have no answer. This view has received great support from the Government and from the Army, both here and in America. It has also been enthusiastically promoted by insurance companies and the Department for Work and Pensions. Millions of public research funds have gone into the pockets of psychiatrists following the Wessely school of thought. The result: seriously ill patients have been denied recognition and treatment, disability benefits and dignity. Stigmatised by Wessely and his followers as malingerers, hypochondriacs, or simply ‘mad’, sufferers of chronic physical illnesses have been left untreated for years, sometimes ending up paralysed, amnesic or even dying. Providing no evidence base for his conclusions, Wessely nevertheless rides roughshod over published medical studies linking vaccine damage, chemical exposure etc with Gulf War Illness (and) toxic chemical exposure (and) viruses with fatiguing illnesses.
