[Dopaminergic agents, COMT inhibitors or amantadine? Proper treatment for your Parkinson patient].

Over the last six years, eight new substances for the treatment of idiopathic parkinsonism (IP) have been approved for use: four oral and one parenteral dopamine agonist (apomorphine), two COMT-inhibitors and budipine. The old drug amantadine has experienced a renaissance in the treatment of a complication occurring during long-term treatment of IP, namely levodopa-induced dyskinesia. Deep brain stimulation with programmable pulse generators and stereotactically implanted electrodes are increasingly being used in patients with severe on-off phases and levodopa dyskinesia. The treatment of Parkinson's disease unresponsive to dopaminergic substances and that associated with dementia remains problematical. In combinations of parkinsonism and dementia, the cholinesterase inhibitors are being used in particular for Lewy body dementia.
