Relief from Parkinson Medication Side Effects

Relief from Parkinson Medication Side Effects Parkinson’s disease affects about 1 in every 100 people. Unfortunately the standard medication used to treat PD can produce serious side effects.

New research is beginning to reveal what causes the side effects.

The standard medication used to treat Parkinson’s is Levodopa, a drug that initially has major benefits but can later also produce serious side effects in the form of involuntary, jerky movements.

The jerky and unpredictable movements that form the side effects of the medication are known as dyskinesias.

It is clear that dyskinesias are caused by long-term use of Levodopa, but researchers have been divided on the exact details of the mechanisms behind them and there has been no good way to study them in laboratory animals. This is what researchers from the University of Lund have now developed.

“We use a harmless virus that introduces a small gene into the nerve cells. In a process involving several stages, the gene causes the nerve cells to stop producing dopamine, without destroying them,” explains Ayse Ulusoy.

In a patient with Parkinson’s disease, the nerve cells that produce dopamine die.

However, at the same time other cells in the brain also suffer changes. This makes it very difficult to find out which of these changes causes the dyskinesias.

In the new model system that Ayse and her colleagues have developed, the laboratory rats’ nerve cells otherwise function normally, allowing reseachers to observe what causes the dyskinesias, the unpleasant side effect of the Parkinson’s medication.

“We have seen that they are linked to the ‘fibre terminals’ on the nerve cells that should release dopamine. These new findings open up great opportunities to improve the treatment of Parkinson’s disease in the long run,” says neurologist Gurdal Sahin.

Researchers have recently published results in the journal PNAS (Proceedings of the National Academy of Sciences).

Experts believe the study will be of great international interest, because Parkinson’s disease exists around the world and the side effects of the medication have long been seen as a very serious problem.
