MODEL RELEASED. Treating Parkinson's disease. Parkinson's disease is a progressive degenerative disorder of the central nervous system, where the muscles become rigid and difficult to control. Parkinson's is thought to occur because dopamine, a neurotransmitter (signalling chemical), is unable to act on the brain cells controlling muscle movement. Apomorphine is a dopaminergic agonist, meaning that it enhances the action of dopamine in the brain and allows muscle movement to be regained. However, apomorphine is only a temporary alleviator, as the effect is short-lived and only lasts about an hour. There is no cure for Parkinson's disease.
