Parkinson's New Zealand says a new clinical trial could result in a remarkable new type of treatment against the neurological disease
The treatment, in which pig cells are transplanted into the brains of affected people, could delay or prevent the effects of the disease by protecting brain tissue which would otherwise die.
Parkinson's New Zealand Chief Executive Deirdre O'Sullivan says people often spend time looking for a cure or preventions but this is a different approach.
"If we could slow down or even stop the development of the disease one someone has got it - that in itself is almost a cure."
Deirdre O'Sullivan says she'd love to see this trial a success and be out of a job.
