Hi Jennifer, >> when he goes to the local PD support group that he seems to always be the only one in the room doing a dance. This statement made me think that this was not normal. WDYT? << The other patients with dyskinesias (for shame or other reasons) simply do not attend the meeting. Your dad chooses to go anyway. Nothing abnormal about that!! >> Would the DBS STN help with this? << Yes, because after a bilateral STN the use of levodopa can drastically be reduced, thus also reducing dyskinesias and hallucinations. >> He has already had a unilateral pallidotomy. << Also after previous pallidotomy, STN gives about the same results. Hans.
