what is a pallidotomy?

Answer 1

In Parkinson's disease, a part of the brain called the globus pallidus is overactive, which causes a decrease in the activity of a different part of the brain that controls movement.

In a pallidotomy, the surgeon destroys a tiny part of the globus pallidus by creating a scar. This reduces the brain activity in that area, which may help relieve movement symptoms such as tremor and stiffness (rigidity).

Answer 2

It's a surgical procedure to reduce involuntary movements or rigidity as found in Parkinsons disease.
