Hi Harebell,
Some neurologists give up too quickly. I realise several neurological conditions are hard to treat, and the drugs are only effective for a short period Very disheartening for any medic....It would not have been my choice.They have a thankless task, no glamour, low status ( compare Surgeons )
When it comes to the choice of what to give the patient, well, every consultant seems to have certain preferences. A Parkinson nurse told me she could recognise which consultant treated a particular patient from the list of drugs the patient had been prescribed.
However, even though this disease has been around for a while, you can not but wonder why after so much effort, time and money (look at the amount the PDS has poured into trying to find a cure) has been put into research the most effective treatment,, the one and only LEVODOPA (available in three main products,:(Sinemet, (Stalevo=Sinemet + Entacapone) and Madopar) has now been around for over half a century. When I was diagnosed in 1999 I got the impression that drugwise Parkinson patients were in for a much smoother ride thanks to some relatively new drugs, the more sophisticated newer dopamine agoniists : Mirapexin , Ropinirole and Rotigotine .All these drugs can have nasty side effects,, which can limit their use.
More was and is still in the pipeline, but it looks like DBS surgery is the most impressive (if it is successful) improvement in the treatment of PD. Not every patient is suitable for this treatment..
So Harebell I am afraid your long list on the internet of drugs for PD is very much a list of "more of the same". It boils down to trial and error,not all drugs give the same benefit to the same patient, some patients seem to do better on Madopar, some on Sinemet, Start with a low dose , try small amounts maybe in combination with other drugs in small doses , be patient and grateful for any improvements , Being well rested, relaxed , no stress, is very helpful. I found yoga very good for this in the early years. All the best, Kate
