title: Gamma Knife thalamotomy and pallidotomy in patients with movement disorders: preliminary results.
abstract: The Leksell Gamma Knife is a useful and safe method to perform thalamotomy and pallidotomy in selected older patients with Parkinson's disease and related movement disorders. In this preliminary report, 2 of 3 patients with severe intention tremor were relieved of their symptoms by thalamotomy, as were 4 of 7 patients with Parkinson's tremor. Four of 8 patients had significant improvement of contralateral rigidity following pallidotomy.
