Disclosed is a polymeric drug delivery system for delivery of any substance to the central nervous system. The delivery system is preferably implanted in the central nervous system for delivery of the drug directly to the central nervous system. These implantable devices can be used, for example, to achieve continuous delivery of dopamine, which cannot pass the blood brain barrier, directly into the brain for an extended time period. The implantable devices display controlled, 'zero-order' release kinetics, a life time of a minimum of several weeks or months even when the devices contain water soluble, low molecular weight compounds, biocompatibility, and relative non-invasiveness. The polymeric devices are applicable in the treatment of a variety of central nervous system disorders including Parkinson's disease, Alzheimer's dementia, Huntington's disease, epilepsy, trauma, stroke, depression and other types of neurological and psychiatric illnesses.
