My husband has Parkinsons disease and I found it all very depressing. What is the point of being able to smell Parkinsons? It does not make the diagnoisis any quicker...my husband had all the typical symptons and he was not diagnoised for over 5 years. He was given excuse after excuse for his symptoms, frozen shoulder, trapped nerves, the list was endless...it was when I insisted he saw a specialist ( as I work with parkinsons disease patients) that he was referred....within 10minutes of being seen he was diagnoised... If we had told our GP that my husband had a parkinsons disease "smell" he would have laughed at us as he could not reconise the typical symptoms....Parkinsons UK stated that they spend millions on research but why is it that the drug recommended for Parkinsons which is meant to be the gold star treatment has been prescribed for over 50yrs....no advance on it...I feel that programmes like this give the public the idea that there is a cure on the horizon....which people like to tell us that my husband will be cured soon....sadly IF there ever is a cure it will be years and years away.....sorry if this sounds negative but when people have to live with someone with parkinsons disease and watch their loved being overcome by this cruel disease....these programmes do nothing to highlight what really goes on and in a way they give patients and the public false hope......
