Reversing Parkinson's

Parkinson’s Disease is one of the major neurodegenerative conditions. Cells die, for reasons not fully understood, causing a reduction in the production of the neurotransmitter, dopamine, and a raft of physical and behavioural problems. Although effective drug treatments are available, they wear off over time and have side effects. The highly individual nature of the condition and variation in its progression also makes dosage difficult. Sue Broom reports on two new approaches that could lead to treatments for Parkinson’s. One potential therapy is to replace the dying cells with new ones. This was tried several decades ago but the results were not promising. The new Transeuro trial of cell therapy hopes to lead to better outcomes. The second approach is to use stem cells. Sue Broom talks to the doctors and patients involved in these trials.
