A method and system for neuromodulating vagus nerve(s) to provide therapy for neurological and neuropsychiatric disorders comprises implantable and external components. The pulsed electrical stimulation to vagus nerve(s) is used for disorders such as epilepsy, depression, anxiety disorders, neurogenic pain, compulsive eating disorders, obesity, dementia including Alzheimer's disease, and migraines. The pulsed electrical stimulation to vagus nerve(s) may be provided using one of the following stimulation systems, such as: a) an implanted stimulus-receiver with an external stimulator; b) an implanted stimulus-receiver comprising a high value capacitor for storing charge, used in conjunction with an external stimulator; c) a programmer-less implantable pulse generator (IPG) which is operable with a magnet; d) a programmable implantable pulse generator; e) a combination implantable device comprising both a stimulus-receiver and a programmable IPG; and f) an IPG comprising a rechargeable battery.
