Abstract: The present disclosure relates to apparatuses and methods for treating neurological disorders by electro-stimulation. In some embodiments, the apparatus includes a stimulation module configured to generate a stimulation signal to be sent to at least one implantable electrode, and an acquisition module configured to acquire a signal measured by the at least one implantable electrode from a patient. The acquisition module may include a front-end block configured to amplify a potential difference of input signals (V1a, V2a) received by the acquisition module and to filter a stimulus artifact by cutting off frequencies above a predefined frequency band. The front-end block may include a multi-stage fully-differential switched capacitor circuit configured for discrete-time signal processing.

Abstract: Disclosed herein are deep-brain stimulation (DBS) systems and methods for the treatment of Tourette Syndrome (TS). The DBS methods described herein comprise a stimulation paradigm that may help to reduce the frequency and/or severity of motor and vocal tics, as well as rapid and involuntary muscle motions that are characteristic of TS. One variation of a method for the treatment of TS comprises adjusting electrical stimulation to a target brain region based on changes or variations in the neural activity signals in the target brain region. One example of a method described herein comprises monitoring the power values (e.g., spectral power values) of one or more frequency bands of the acquired neural activity signals and adjusting electrical stimulation parameters based on at least one variation or change of the monitored power values.

Abstract: In some variations provided herein, a system for deep brain stimulation includes an implantable device that acquire and store neural activity signal records and apply electrical stimulation. The system further includes a personal controller device that establishes a first wireless connection to the implantable device. The personal controller device transmits power to the implantable device, and the implantable device transmits neural activity signal records to the personal controller device over the first wireless connection. The system further includes a clinician programmer device that receive the neural activity signal records from the implantable device by establishing a second wireless connection based on activation of the first wireless connection. The clinician programmer device sets one or more stimulation parameters based on the neural activity signal records.
