New drugs which may have the potential to stop faulty brain cells dying and slow down the progression of Parkinson's, have been identified by scientists in a pioneering study which is the first of its kind.

Experts from the world leading Sheffield Institute for Translational Neuroscience (SITraN) conducted a large scale drugs trial in the lab using skin cells from people with this progressive neurological condition which affects one in every 500 people in the UK.

The researchers tested over 2,000 compounds to find out which ones could make faulty mitochondria work normally again. Mitochondria act as the power generators in all cells of our body, including the brain. Malfunctioning mitochondria are one of the main reasons why brain cells die in Parkinson's.

One of the promising medications identified though the research is a synthetic drug called ursodeoxycholic acid (UDCA). This licenced drug has been in clinical use for several decades to treat certain forms of liver disease which means that researchers will be able to immediately start a clinical trial to test its safety and tolerability in people with Parkinson's.

This will discover the optimum dose to ensure that enough of the drug reaches the part of the brain where Parkinson's develops. Based on this information, larger randomized controlled trials can be carried out to assess the potential of UDCA to treat Parkinson's.

The extensive drug screen, which took over five years to complete, was funded by leading research charity Parkinson's UK, and was carried out in collaboration with the University of Trondheim, Norway.

Dr Oliver Bandmann, Reader in Neurology at SITraN, said: "Parkinson's is so much more than just a movement disorder. It can also lead to depression and anxiety, and a host of distressing day to day problems like bladder and bowel dysfunction.

"The best treatments currently available only improve some of the symptoms, rather than tackle the reason why Parkinson's develops in the first place, so there is a desperate need for new drug treatments which could actually slow down the disease progression".
