Stem cell therapy for Parkinson’s disease: researching for an effective cure

Neurodegenerative diseases are characterised by the chronic and progressive loss of neurons, which in turn results in loss of cognitive and physical functions. The World Health Organization has estimated that the disability-adjusted life years lost from neurological disease was about 92 million in 2005 and has projected that this will increase to 103 million by 2030. Unfortunately, no drugs are currently available to halt the progression of these disorders and all that can be offered in the clinic are symptomatic therapies.
