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.
