1. A method of assessing efficacy of a neural modulation therapy delivered with an implanted device to a subject with a neurological or psychiatric disorder, the method comprising: monitoring the subject's response to a plurality of previously delivered neural modulation therapies with an implanted device; wirelessly transmitting data that is indicative of the subject's responses to the neural modulation therapies from the implanted device to an external device; storing the data that is indicative of the subject's responses to the neural modulation therapies in a memory external to the subject's body; storing a plurality of parameters of the neural modulation therapies in the memory external to the subject's body; and analyzing the data that is indicative of the subject's responses to the neural modulation therapies to assess an efficacy of the delivered neural modulation therapies.
