1. A system for treating a neurodegenerative disorder resulting in degenerating neurons forming part of a central nervous system comprising in combination:
- an implantable pump;
a catheter having a proximal end coupled to said pump and a discharge portion for infusing into a predetermined infusion site in said central nervous system a therapeutic dosage of at least one drugs capable of altering the level of excitation of neurons in said brain related to a degenerating neurons;
a sensor for generating a signal related to an attribute of said nervous system which indicates the hyperexcitation of said degenerating neurons or of neurons related to said degenerating neurons; and
control means responsive to said sensor signal for regulating said therapeutic dosage.

Abstract
Techniques for infusing drugs into the brain to treat neurodegenerative disorders by system of an implantable pump and catheter. The drugs are capable of altering the level of excitation of neruons in the brain. A sensor is used to detect an attribute of the nervous system which reflects the hyperexcitation of the nerve cells projecting onto the degenerating nerve cells. A microprocessor algorithm analyzes the output from the sensor in order to regulate the amount of drug delivered to the brain.
