The gamma knife directs more than 200 thin beams of gamma radiation at different angles toward a single point in a person's brain. While each beam delivers a trivial amount of radiation, the spot where they converge receives enough energy to destroy that tissue, making the gamma knife a precision tool for attacking small tumors , malformed ...
Leeds Gamma Knife Centre is based in the Institute of Oncology at St James's University Hospital in Leeds, West Yorkshire, England. St. James's Institute of Oncology (Bexley Wing), a National Health Service (NHS) hospital, is the largest cancer research hospital in Europe. [ 1 ]

Obsessive–compulsive disorder (also known as OCD) is one of several anxiety disorders that affect approximately 1-3% of the general population. Subcategories for this disorder can include clinical information about the disorder, persons who are affected by it, and organizations involved in researching and advocating about obsessive–compulsive disorder.
[2] OCD is a mental disorder characterized by obsessions and/or compulsions. [3] An obsession is defined as "a recurring thought, image, or urge that the individual cannot control". [ 4 ] Compulsion can be described as a "ritualistic behavior that the person feels compelled to perform". [ 4 ]
Moreover, OCD has been associated with a malformation of the basal ganglia. [11] The function of this part of the human brain has been mapped to be composed of fiber tracks associated with numerous parallel cortico-striato-thalamocortical circuits (CSTC), which are involved in sensorimotor, motor , oculomotor as well as the cognitive processes ...
Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
