Non-invasive delivery of stem cells to the brain could dramatically improve the symptoms of Parkinson's disease, a study has found.
Research published in journal Rejuvenation Research delivered mesenchymal stem cells (MSCs) to the brains of rats through the nose and successfully reversed the dopamine deficiency seen in the disease.
Levels of dopamine were significantly higher in the areas of the brain which had undergone the treatment and motor functions were seen to improve by up to 68 per cent.
This comes after one expert said that there are no known drugs or lifestyle changes that can prevent the onset of Parkinson's.
Dr Kieran Breen, director of research at Parkinson's UK said that some people develop the condition due to a combination of genetics, lifestyle and environment.
"Parkinson's is a condition that probably takes many years to develop. And as we age our bodies are less resilient - cuts and bruises take longer to heal, and we are at greater risk of all kinds of health issues - cancer, heart problems [and] stroke," he said.
