The main purpose of this study is to investigate whether Deep Brain stimulation has a positive effect on the motor and cognitive symptoms in Huntingtons patients. Deep brain stimulation (DBS) is a surgery to implant a device that sends electrical signals to brain areas responsible for body movement. Electrodes are placed deep in the brain and are connected to a stimulator device. Similar to a heart pacemaker, a neurostimulator uses electric pulses to regulate brain activity. DBS treatment has been used for some people with Parkinsons disease. Both safety and efficacy will be investigated in this study with 50 participants. 25 participants will be stimulated with the DBS for the first period of 3 months and their performance on a variety of tests, will be compared with the 25 participants who don’t get any stimulation. After the first 3 months, all participants will be treated with DBS for another 3 months.

Estimated Study Completion Date: 31 December, 2022
