Apparatuses and methods support multi-modal operation of a medical device system for a nervous system disorder. The medical device system comprises an implanted component and an external component and supports a first feature and a second feature that are associated with the treatment therapy. The medical device system supports both features when the implanted component and the external component are coupled. If the external component is decoupled, the implanted component continues to support the first feature. Moreover, the embodiment may support a plurality of features during a treatment interval. Another aspect of the invention allows for modularly expanding a medical device system in order to add a feature that enhances existing functionality or that provides additional functionality. In an embodiment, a module that is associated with an external component of the medical device system supports the added feature.
