1. A method for assisting a user to optimize an electrode lead configuration for providing deep brain stimulation (DBS) for a patient using an electrode lead implantable in the patient's brain, wherein the electrode lead comprises a plurality of electrode contacts, the method comprising:
receiving parameters specifying a first stimulation location on the lead at which to provide stimulation, wherein the first stimulation location was previously determined using a first lead optimization algorithm,
receiving a first one or more values for one or more features extracted from recorded first evoked potentials (EPs) that were previously determined during the first lead optimization algorithm,
providing stimulation to the patient using the first stimulation location and recording second EPs evoked by the stimulation,
extracting a second one or more values for the one or more features from the second EPs, and
comparing the first and second one or more values to determine if the lead has moved since the first lead optimization algorithm was performed.
