Hi! I had gone through your query and understand your concern. Parkinson’s disease is a type of movement disorder characterized by slowness of movement, shaking, stiffness, and in the later stages, loss of balance. It usually happens when nerve cells in the brain don’t produce enough of a brain chemical called dopamine. Parkinson s disease (PD) is a chronic and progressive movement disorder, meaning that symptoms continue and worsen over time. Syndopa is a combination of levodopa and carbidopa (the equivalent of Sinemet in the US) and comes in various doses of the two constituents. Typically this medication will replenish the deficient dopamine stores in the brain and result in less rigidity, less tremor and improvement in ability to move and walk. Yes she has to continue this medication for a long time. Rasagiline is a medicine that is used to slow disease progression and to help Sinemet work better but I suggest you to consult a neurologist because she need to be under professional care to monitor the disease progression. He will give you the right advises related to the treatment (drugs and appropriate dosage considering the severity of clinical findings) Hope I was able to help you. Take care. Dr.Rovena
