Global Deep Brain Stimulation Devices Market was valued at USD 950 Million in 2020 and is anticipated to grow at USD 1828 Million till 2027 recording a CAGR of 9.8.% during the forecast period 2021-2027. Deep Brain Stimulation Devices Market therapy is a surgical treatment for patients with movement and neuropsychiatric disorders. Deep brain stimulation procedure involves implantation of devices known as a neurostimulator, which sends the electrical signals through implanted electrodes to specific targets of brain. Deep brain stimulation devices are surgically implanted and battery-operated medical devices similar to heart pacemakers. It is indicated in Parkinson’s disease, essential tremor, dystonia, major depression, and obsessive-compulsive disorder. Researchers and scientists are gaining valuable insights into the mechanisms of deep brain stimulation, discovering new brain targets for existing and new indications, and refining targeting techniques and post-operative programming techniques for optimising clinical and therapeutic outcomes thanks to ongoing research and a growing number of clinical trials on DBS. A number of clinical trials have been done in recent years to evaluate the therapeutic efficacy of deep brain stimulation as a treatment option for individuals with behavioural, functional, and cognitive deficits caused by Alzheimer’s disease. Implantable electrodes that accurately assess brain activity and administer electrical stimulation to specific brain tissues are becoming more common in the treatment of a variety of neuropsychiatric illnesses and neurological diseases. Flexible thin-film electrodes have gotten a lot of interest in recent years because they reduce the rate of damage and invasiveness during implantation. Researchers are also working to improve the mechanical and electrical qualities of electrodes so that electrical impulses can be securely delivered to the brain.
