Parkinson's Disease is a progressive neurodegenerative disease resulting in disorder of movements, autonomous functioning and in some instances cognition. In a Parkinson's patient, dopamine which is an important neurotransmitter responsible for movement among other things, is depleted. Therapy therefore is mainly based on replacing dopamine, relieving symptoms and improving functioning status. Some dopaminergic drugs available for treatment include Levodopa, Dopamine agonists, MAO-B inhibitors, Amantadine, and COMT inhibitors. Some surgical options are also available. Unfortunately, there is still no definite cure for Parkinson's disease.
