Bilateral cingulotomy
Bilateral Cingulotomy
Bilateral cingulotomy (pronunciation: bi-lat-er-al sin-gu-lo-to-my) is a form of neurosurgery that involves lesioning of the cingulate gyrus, a part of the brain's limbic system. This procedure is typically used as a last resort treatment for severe obsessive-compulsive disorder (OCD) and major depressive disorder (MDD) that have not responded to other treatments.
Etymology
The term "bilateral cingulotomy" is derived from the Latin words "bis" meaning "twice" and "latus" meaning "side", referring to the procedure being performed on both sides of the brain. "Cingulotomy" comes from the Latin "cingulum" meaning "girdle" and the Greek "tome" meaning "cutting", referring to the cutting of the cingulate gyrus.
Procedure
In a bilateral cingulotomy, a neurosurgeon creates small lesions in the patient's cingulate gyrus. This is done using a technique called stereotactic surgery, which involves the use of three-dimensional coordinates to locate the target area in the brain. The goal of the procedure is to disrupt the overactive neural pathways that are believed to contribute to the symptoms of OCD and MDD.
