My sister Rose is in final stage PSP and is now at risk of choking and is on a pureed diet and the nursing staff have had to remove her false teeth. Also have changed from sinemet tablet to madopar liquid and Rose remarkably has been communicating again! Able to answer us and even answered a question on a quiz show on the t.v.! Nursing home is amazed as are we, could it be the change in medication? Anyone experienced this?
