Freebase

  1. Pallidotomy

    Pallidotomy is a neurosurgical procedure whereby a tiny electrical probe is placed in the globus pallidus, which is then heated to 80 degrees Celsius for 60 seconds, to destroy a small area of brain cells. Pallidotomy is an alternative to deep brain stimulation for the treatment of the involuntary movements known as dyskinesias which can become a problem in people with Parkinson's disease after long-term treatment with levodopa — a condition known as levodopa-induced dyskinesia. It is also sometimes used in alternative to deep brain stimulation to treat difficult cases of essential tremor.
