A number of clinical trials have already been conducted in PD with potential neuroprotective drugs but their ability to slow the disease process has been controversial since these drugs have a direct effects on the symptoms of PD itself. Hence it is difficult to say whether the beneficial effects of the drugs are due the prevention of further neuronal loss thus slowing the disease or whether they improve the patient's ability to move directly. PD progresses in most patients fairly slowly, hence we don't expect to see detectable neuroprotection following 6 months Deferiprone treatment but it will allow us to assess whether Deferiprone therapy has any direct effects on PD symptoms. Hence the second aim of this study will be to examine whether iron chelation therapy has a direct effect on PD symptomology.
