Introducing one or more stimulating drugs to the brain and/or applying electrical stimulation to the brain is used to treat Huntington's disease. At least one implantable system control unit (SCU) produces electrical pulses delivered via electrodes implanted in the brain and/or drug infusion pulses delivered via a catheter implanted in the brain. The stimulation is delivered to targeted brain structures to adjust the activity of those structures. In some embodiments, one or more sensed conditions are used to adjust stimulation parameters.
