My father has been suffering from Parkinson's disease since 2007. Now it has reached a maximum severe condition. He has been taking levodopa supplement (Syndopa (levodopa carbidopa: 250 25) which has been wearing off and causing side effects like Involuntary movement, occasional dementia and he is becoming weaker day by day. We have consulted numbers of doctor including Neurologist, Medicine specialist and we could not find a better alternative of the drugs. We used Tridopa 100 (another levodopa supplement) but the dosage is not working for my father. What I an interested to know if there is any better treatment of this disease? His health is deteriorating day by day. Please let me know.
