My father is diagnosed with Parkinson disease. I have added the medications which he was taking for almost 6 months. Now he is taking Syndopa plus, lonazep, excelon tablets. In spite of taking the tablets he seems to be having no improvement in his body. He feels dizziness, hands shivering, unexpected smiling etc through out the day. Can any of you suggest a good remedy for it. If taking or eating anything else will improve the condition then do suggest that also.
