A breakthrough that led to the creation of new neurons in mice could be used to transplant brain cells in Parkinson's patients and cure them of the disease. Parkinson's disease is characterised by a loss of dopaminergic neurons in a region of the brain responsible for reward and movement - replacing those cells could help to reduce or even reverse the symptoms of the degenerative disease. A small study involving mice with Parkinson's saw those given the 'new neuron treatment' return to normal within three months and stay disease free for life. They also added it to the part of the brain that typically loses dopamine-producing neurons in Parkinson's disease. They remained completely free from symptoms of Parkinson's disease for the rest of their lives but the control group showed no improvement.
