"There are few data sets available that follow PD [Parkinson's Disease] patients over a long period" comments Dr Olivier Rascol, lead investigator of the study. "These findings emphasise the importance for us, as physicians, to consider, among other aspects, the long-term implications of treatment, so that patients are provided with the best possible prognosis. The findings also support the early use of ropinirole as part of a long-term treatment strategy for PD patients." Parkinson's Disease is a complex idiopathic disease with a variety of treatment options and no single treatment solution or pathway. These new data indicate that early treatment decisions can make a difference to a patient's long-term disease management and quality of life. Professor David Brooks of Hammersmith Hospital, London, says "It is important to consider a treatment strategy that benefits patients in the long-term. The optimal treatment plan should extend the window of wellness by effective drug sequencing. This will allow people with PD to continue performing their daily activities for as long as possible without having to contend with dyskinesias at an earlier than necessary stage." Study protocol Patients who completed the 5-year comparison of ropinirole and L-dopa (Study 056, Rascol et al, 2000)[2] could enter this 5-year follow-up study (protocol 101468/170). 268 patients were randomised to the original Study 056; 130 completed the trial and 69 entered the recent study (42, ropinirole; 27, L-dopa). Of the 69 patients that entered the recent 10-year follow-up study, 46 were followed up for the entire 10 years. Main demographic variables in this subgroup were similar to those initially randomised to Study 056. Patients received investigator-selected treatment during follow-up, unrestricted by their original randomisation. Treatment efficacy and incidence of dyskinesias were assessed every 6 months using the Unified PD Rating Scale (UPDRS). Results are reported for the original randomisation groups (regardless of current therapy). Notes on study findings * These results are representative of the 69 patients who entered the follow up study ¥ This finding applies to the 46 patients who completed the 10 year follow up Parkinson's Disease incidence in the UK In the UK, one in 500 people has Parkinson\'s Disease (currently around 120,000 individuals). Each year, about 10,000 people in the UK are diagnosed and statistically slightly more men than women have the condition. It is estimated that four million people worldwide have Parkinson's Disease.[3] About dyskinesias Dyskinesias are unwanted, excessive and abnormal movements that are seen in patients with PD after a certain number of years with the very treatments that manage the disorder by increasing dopamine levels in the brain (levels of which are progressively depleting due to the nature of the disease). For these individuals, the battle against dyskinesias, though not painful, can be extremely distressing and detrimental to their quality of life. Trial investigators O.
