Regrowth of dopaminergic neurons: a new treatment strategy for Parkinson’s disease?

Little is known about the molecular causes of Parkinson’s disease. However, there is evidence linking the loss of dopaminergic neurons to the tremors and motor problems that are experienced by patients with the disease. Up until now this loss has been considered irreversible, but a new study led by Brad Morrison from Boise State University (ID, USA) suggests that dopaminergic neuron regrowth may be possible. The results of the study were published recently in the journal Neuroscience Letters. Dopamine is involved with emotional response and also plays a key role in movement. The results of the study indicated that the rate...
